electrical diagram crf230f

Asking for help because in don't know much about electrical stuff, heres my situation;

The bike is like new 2004 with under 10 - 15 hours on it.

Didn't ride it for a season and the battery went dead.

Went and bought a new battery bike ran and I took it out for the day.

2 weeks later went to start the bike, wouldn't start so I charged the battery and it started then I turned it off.

Went to start it again immediatly after I turned if and would start, checked the battery and it was good.

I replaced the main fuse and still nothing.

I bought a new starter relay, still nothing.

checked the kill switch and clutch switch and still nothing.

Any help would be great, don't no what to try next??

You need to get a test light or a meter and trace the 12V through the system to see where you are losing it. I don't have an electrical diagram, or I could give you a step by step. One quick test would be to jump the batter + directly to the starter connection to see if the starter is OK. It should turn over and possibly even start. This only tells you one thing though, whether the starter is working or not. Could be a bad connection anywhere, you just need to find it. Hope this helps.

Thanks, I did do that and the starter turned over.

The easiest thing to check then would be the start switch. Make sure that it is closing when you push it by checking OHMS across the two wires. Could be as simple as a bad start switch. Hope this helps.

When you did the thing to turn the starter over did it run? Did it sound like it wanted to run? Check for spark by taking the plug out and resting the threads on a bare metal ground. try turning it over and see if it has spark. If it does put the plug in and try starting it a few more times. If it wont fire clean the carbs and try again. If it still wont start im stumped.

do what Dylan said and check for a spark. check to see how much compression it has. Try bump starting it as well if it starts up this way then it is definitely an electrical problem and not a fuel or air problem.

How about a little clarification here. Does it turn over normally? If so, tell us in as much detail what is happening when you push the start button. I was under the impression that it would not even turn over. If it turns over then you are chasing the wrong tail with the start button and jumping to the starter. As stated above, try to bump (push) start it and see what happens. Let us know, and we will help you get this beast running again.

I have found the problem its the ignition switch. Has anyone bypassed the ignition switch? it would be nice not to use a key to turn it on.

Thanks for everyones input its very appreciated.

hold on. are you telling me the bike didnt start because you didnt turn on the key?

hold on. are you telling me the bike didnt start because you didnt turn on the key?

NO....I would never be able to return to this forum if that was the case :thumbsup: . The ignition is defective (and so soon too). I want to get rid of ther ignition switch but not sure if that would drain the battery by doing so?

I doubt it would drain the battery if you bypass the switch. My first question would be what is going through the switch? I assume it serves two purposes, kill switch and ignition enable. If these are the only two functions then you could remove the switch, and splice the ignition wires together. DO NOT SPLICE THE KILL WIRES together or you will never get the bike to start. Your best bet would be to put an Ammeter in line with the battery to see if it starts drawing current whith the ignition switch bypassed. If you could provide me with an electrical drawing for the 04 CRF230 I could tell you exactly what to do. Hope this helps.

Great thanks Josh here it is let me know, I'm not good at electrical:bonk: thankyou

It looks to me like you need to jump the black and red wires on the ignition switch together and separate the black wire with white stripe from the green one. To test this, unplug the ignition switch and connect the red and solid black wires together using a jumper wire, then try the starter switch. If it works then you can jump these two wires together permanently and leave the connector unplugged. Wrap the whole works tightly with electrical tape to keep water out and enjoy your ride.

I may be able to make it a little more clear even. If you look at the right side of this drawing, you will notice a legend of how each switch works in on and off situations. You will notice that when the ignition switch is on, the batt1 and batt2 wires are connected together and the E and IG wires are open or disconnected. This is the condition we want to get the connections into in order to be able to use the starter button. I don't see any reason that this would cause any drain on the battery, you should be good to go here, but be aware that you are losing the security of having to have the key to run the bike. I would try to make the ignition switch look like it is still in use so that it is not obvious that you no longer use the key. Let me know how it turns out, hope this helps.

Josh

Got it done, thanks for the help I'm starting to understand it more as I work with it. I left the ignition in so it looks correct I also pulled power between the bl and red to a fuse then a switch for a headlight. Kicks butt thanks!

No problem, always glad to help. Just a suggestion though, I would rather see you pull your headlight power directly from the battery. The only reason I say that is because as you have it set up right now you are going to be pulling the light current through the starter relay. This in my opinion is causing an undue strain on the relay and could cause it to fail prematurely. I would wire the light as you have only move the black wire to the negative terminal on the battery and the red wire to the positive terminal. Keeping the fuse in place. The way you have it wired now will work fine, but If it were mine I would try to move the power and ground off of the starter relay. Keep it dirty side down!!

Josh

Good idea, I have the light grounded to the front of the frame, do I need to relocate to the neg. on the battery or can I leave the ground where it is?

The frame ground will be fine, just relocate the + and you will be good to go.

      Hello all,
      I have a 2005 crf230f im wanting to modify my bike as best as possible for a sumo style bike. My first thought was an engine swap.
      Has anyone done an engine swap on this bike before? If noone has what engine would be the best fit to do so?
      The 230cc engine desnt have enough umph to really be a daily driving unless taking backstreets all the way to work so im trying to see what i can do to make it have the umph.
      Some of the mods ive done include the airbox mod, a lighting kit, sprocket change (i believe i have a 42 and 13 but cant rememebr), and a jetting mod where my dad took the stock jets and drilled it out just significantly enough to make her kick as much as she can.
      Im looking at doing handlebar risers, an airbox mod on the right side of the bike for even more airflow, cr500 shock if possible. 
      I am absolutely in love with the turning radius and nimbleness this bike has. I have ridden my dads BRP and my brothers crf450r and they just cant skirt around the world like my bike can so im trying to get the power (hopefully) of a bigger bike in the body of my bike. 
      Im not looking to have to completely tear the bike down to modify the bike, but if need i can make it happen. Before i am forced to modify the frame to accept another engine, are there any straight swaps that can happen? Are there any other performance mods that can be done to get that speed a little higher without sacrificing too much reliability?

      I have an 03 CRF150F that has a pretty bad wobble in the front wheel.  It has the OEM rim on it, 19x1.40 w/36 spokes.  For some reason, Honda is REALLY proud of their CRF150F rims, and want $125 for a new one.  However, the same size front rim from an XR/CRF100 or CRF125F are only $25-$30.  I realize that the spoke/nipple sizes are different, but is there any reason I couldn't use an XR100 rim and lace it with CRF150F spokes if I drilled the holes out larger?  Could nipple size be an issue?  Center well depth?
      I'm not looking for weight savings, or bling, just a straight wheel assembly.
      Or, if nobody knows the drop-in capability, I sure could use a lesson in spoked wheel compatability.  Does anyone know a good site for learning what features really matter when trying to swap rims?
      Thanks for the insight in advance.

      They will fit with some modification I did it on my bike 2007. The 2015 through 17 has an extra mounting hole on the tank and shroud so I cut the threads off an extra mounting screw and superglued it in that hole giving it a more authentic look. Except I didn’t use enough glue on the right side and the screw fell out. I had to use spacers on the front mount. And drill a new hole on the original tank mount but that doesn’t effect the original shrouds mounting. And a new hole on the new shroud. The new shrouds also sat correctly against the tank not affecting the seats look. Pictured is the two shrouds next to each other and the bike with the original shrouds. Also pictured is the listing for the shrouds and I only  spent $30 AUD on the OEM shrouds which were listed at $35 after my offer was accepted. They came with new hardware. And it was well worth it. I hope this post was worth the time😂.

      SOLVED*** No timing issue, just had trouble lining up TDC  Going to rebuild top end to fix low compression. Thanks for the help TT
      So I bought my 2003 crf230f a few months ago from a friend. The bike has definitely been ridden, and was blowing a little bit of smoke when I bought it so I knew the rings would be toast sooner or later. After a basic tune-up the bike ran really strong and I continued to ride it a few times a week for a couple months with no problems... Until last week when I was riding and it died on me. At the moment when the bike died, I was coasting down a hill so there was no extra stress on the engine, I just noticed the engine shut off- almost like running out of gas.
      From that moment on, the bike would not start so I towed it home and checked the essentials... Air, Fuel, Spark, Compression.
      Air- The new air filter I installed when I bought the bike was already covered in dust, so its possible the piston rings got even more dusted. I cleaned and oiled the filter anyway (the bike wouldn't start with the filter removed).
      Fuel- I recently changed my jetting to Mike Coe specs, and installed a larger pilot jet to eliminate popping on deceleration. The bike ran great with the new jetting and I know the carb is clean. I went ahead and cleaned out the gas tank and fuel lines and cleaned out the carb yet again.
      Spark- Spark plug was white due to running lean before I changed the jetting. Plug turned more of a brown color after jetting, indicating better A/F ratio. Replaced spark plug anyway and can see strong blue spark. Also, gas is making it to the plug.
      Finally did a compression test and had low compression. I adjusted the valves which were a bit out of spec, and saw no improvement. A wet compression test (one tsp oil in plug hole) showed higher compression, but still low, indicating the piston rings are toast. I ordered new rings and top end gaskets and will rebuild the top end next week.
      I was also wondering if I have a timing issue, since the engine at TDC (pic 1) shows the cam sprocket about 30 degrees (in the retarded position?) off from being horizontal with the head, as it should be according to the FSM and Clymer manuals. Also, when cranking the engine CCW by hand, the flywheel tends to spin past TDC and happens to align the cam sprocket perfectly horizontal with the head. Is my timing way off? Also, the flywheel has a || mark (pic 2) near TDC that I used to adjust the valves. Just today when I took the pictures, I noticed a |F mark (pic 4) that usually spins past quickly so I never saw it before. both marks appear close to TDC but the engine always wants to spin to the natural position (pic 5). Where is my true TDC? Manuals only show a |T mark. Are the cam sprocket lines supposed to be horizontal with the head? Maybe it jumped a tooth? I have read the cam chain tensioners are known to fail also.
      Edit: Found the T mark, updated photo near bottom of thread
      tl;dr
      Bike died on me, has low compression, going to rebuild top end. See pictures. Could this be a timing issue also? Does anyone know if the lines on the camshaft sprocket are supposed to line up with the horizontal lines on the head? Thanks in advance for the help!

      Pic 5- Engine wants to spin to this position: Cam sprocket lines horizontal with head- https://imgur.com/S3rPRgd
       
      Let me know what you guys think. Has my timing jumped? I appreciate your help!
      Cheers,
      Spencer
       
      Edit: Finally found the damn "T" mark. Always spins past so I wasn't able to see it before. Updated picture posted near bottom of thread. Timing looks fine so  just going to rebuild top end next week to restore compression
