so I'm reposting this under a new heading since I think I've zeroed in on the problem.

Thought it was the fuel pump. Turns out that when the battery is fully charged the bike runs fine, but slowly drains the battery until she dies. So, I started it up, checked the power coming out of the stator 30V across all 3 wires. Then moved on to check the DC output of the regulator/rectifier. And here's where I'm confused.

There are 4 connectors, each of these read at ~6.3V-7.8V as I revved the engine. I assumed that I should add them together (i.e. my total output is 12.6V-15.6V) which would mean it's normal. Then I found this..... http://www.inwa.net/~m3047/rect-reg/rect-reg.html which talked about half-wave vs. full wave rectifiers. It mentions that if one of the diodes goes bad, I would only be getting half the correct voltage output.

So does anyone know what the output wires of the R-R should be?

I'm really starting to hate troubleshooting electronics......

k ohms

red/white - green -> infinity

red/white - yellow -> infinity

green - red/white -> 1~20

green - yellow -> .5~10

yellow - red/white -> .5~10

yellow - green -> 10~200

I've got the same exact problem. New Rectifier comes on Monday. Ordered from Electrosport. Really slow and bad customer service. Over a week for a part to get from Oceanside CA to LA. I could've driven and picked it up. And I think shipping was like $11. Ridiculous. Hope product is better than what's happened so far... Also hope this fixes battery drain problems, will let you know.

I am having the same problem with my 89 600 F I am ordering a new Voltage Regulator/ Rectifier tomorrow and it takes 1 days to get it from the local shop. However a after market part does cost $105.00 Are these easy to instal?

pretty straight forward, pull old one out, put new one in. have to remove fuel tank (don't even have to disconnect fuel line, just move off to subframe) and airbox.
