2006 WR450 with Charging Issue
Posted October 31, 2008 - 06:45 AM
1- At the battery positive and negative cables at idle, I was getting 4-6 volts
depending on rpm (no battery installed).
2- I pulled the main plug at the fuse block and noted some corrosion
at the clips and cleaned that up. The fuses checked out fine.
3- I started the bike again with the main plug at the fuse block connected, and
checked the output at the positive and negative cables and had 8-volts at idle but when rpms were raised it dropped to 5-6 volts.
By the wiring diagram the next thing down stream is the voltage regulator followed by the ac/magneto (?). The plugs to test the voltage regulator are pretty unaccessable (at 11pm).
I also tested the main on/off switch and it passed before I figured out it has nothing to
do with the charging system…duh.
I was wondering:
A) If anyone has had similar problems, and was it the voltage regulator?
Can the voltage regulator be tested when completely disconnected?
Or is my positive/negative cable test adequate?
C) Do these bikes tend to eat voltage regulators or should I be doing a strip and
search for frayed wires? I use to have a VFR that liked a voltage regulator
every other year?
As an aside, it was nice to find that it is so easy to kick over (once warm) and is an absolute hoot to ride.
Thanks for your time.
