yz426 rebel 250 chopper battery help

Recommended Posts

Ok so i put a yz426 engine into a rebel 250 frame. I put in a wr450 stator and did the pink wire mod (not sure on the color). So i rode it around just fine for a couple months with no battery and now my fans for my radiator and my headlight burnt out. So i figured maybe it got messed up because of the wrong voltage. By the way the stator wire is ran through the rebel regtifier thing to give my dc power. So since i blew up the lights and fan I decided to add a small 12 volt dc scooter battery. So I hooked up the + on the lights to the batt but the new lights did not work till i disconnected the grounds from the frame and hooked them up to the negetive on the battery. So now the way i have it ran is negatves to batt and positive from the rectifier is a T to the lights and one to the batt. So now the lights work but if i disconnect the batt positive the lights wont work with the bike running. So i think maybe i have to take one of the grounds off the frame and hook it to the battery negative so that the lights will work if the batt is dead but i dont know what one. Oh and by the way, does anyone know where to get a fan for my radiator? I used to small computer server fans but i figure there must be one meant for a bike somewhere.l_4410e0950e284668af6e53dd79f0899b.jpg

i thought about that, but frm what i am reading on here. it is not good to mount the ac ground and dc ground both to the frame. I think i just need to figure out what wire is the ground wire to the lighting coil and hook that to the battery so that way the entire lighting system is on a floating ground. I will try to get a video for you once i get the light thing figured out.

Hey I have a rebel 250 also and that looks like a cool project. How hard was it to mod the frame and exaust and where did you mount the rads

I did not mod the frame. I built a bracket to hold the radiator. and i used the stock header and conected bendy tube with a car mufler tip

ok does anyone know how to tell if power is ac or dc. cause when i hook a volt meter to a car batt it says 24ac in ac setting. Cause when i measure the power from the lighting coil at idle i dont know if i am gettng 12ac or 6volt dc.

I only have a wr stator. It is a yz motor, that is why i am using some rebel parts.

I do have a wr426 stator, not sure why i said 450. But i just have to get the light stator ground off the frame and to the battery. So i will be trying to figure out where the stator ground is today.

ok so here is the deal. I remember doing the pink wire mod to get the lights to work without the battery. But now I want a battery and best i Can tell is that the pink wire is the ground wire for the lighting coil. So right now the pink wire coming out of the stator is cut and the pink wire that runs to where ever, cdi i guess is grounded to the frame. So i am thinking that maybe the pink wire that is cut maybe should go to the ground on my battery for the battery to charge. Does anyone know if that is right?

Ok you have a wr426 right? There is no battery for that motor. So are you using both the WR and Rebel wiring harness' together some how?
