I learnt how to use the multimeter a little better over the last few days, in series between the NEG battery post and the NEG wire I was getting ~.02A drain.

Frustrated and resigned to the fact that it needs more attention, I proceeded to disconnect every wire in the bucket one at a time while watching the meter and found one red/yellow wire that lowered the 'leakage' from .02A to .01A when unplugged.

Then disconnected *every* other wire on the bike while watching the meter and found the only thing that got it to 0.0A was disconnecting the fuse box. I'm beginning to think a little 'leakage' may be 'normal'

I'm in the process of checking all the wiring to the handlebar switches and gauges, found a few dodgy wires. I still have to get inside the alternator to check it.

The up-side, I'm getting very good at dis- and re- assembling a 33 year old Yamaha. And my fancy new Regulator/Rectifier arrived yesterday, but I'm going to try to get everything sorted before I install it though.

I really appreciate the help, and kind words.

You guys have been more help than the 2 stroke forum, stands to reason I suppose, V-Stromers are generally good people!

I have a UK RD400F with a similar problem to yours,bike starts and runs okay but blows the 10A brown wire fuse when I turn on the ignition.This means I have no oil/neutral light or horn/indicators.Did you find the cause of your problem,cheers

I bought one in 1977 and sold it in 2008 to make room for the Strom. I loved that bike.
