Ignition / electrical issue

Recommended Posts

Hi all,

Bought a 2007 WR450F a couple months ago. Electric start was working fine, and worked for a few weeks without issue. Recently the red ignition button light stopped glowing when clicking the On/Off button and readying to start. I kick started to get it home without problem, and kicked to start a few time after that without problem. When I got around to looking into it, the battery read at 11V. I replaced the battery and a blown 10A fuse on the positive (right hand) side. Also noticed that the 90 degree inlet on the carb was leaking, so I replaced the 3 O-rings (# 3TJ-14564-40-00) to stop the leak.

Upon starting, the bike idled fine, and ran great for about a half mile before dying. Again, red ignition button light stopped glowing. My *assumption* is that the fuse blew again, but I cannot yet confirm. I was on my way to work, so I haven't had time to look into it yet. I'm fairly strong mechanically, but don't know much about electrical. My guess is that this is not an easy fix-- maybe a short, and I'm looking for advice on where to start.

I appreciate the help guys!

You need to:

Clean the harness connections at the stator, all grounds, and at the harness under the left side plate

Get a factory service manual and perform the tests on the Stator and Rectifier, to see if they are failing

 

Usually, it's just a corroded ground wire somewhere...
