Ok so no Help on this just odoer one of ebay new one so lets hope it work

 

I just picked up a 93 F2 for Free Previous owner says it needs an alternator. In my research it seems R/R are a common fault. I jumped the bike because the battery is completely flat. I took the jumper off once it started and it stalled so I put the jumper back on it and let it run for a few minutes and then pulled the jumper pack off and everything got dim. So I checked the battery and it was at like ~8-9V. Would you start with the R/R or stator/alternator?

 

Good price , sounds like the R/R to me did you check the resistance? You'll need a new batt as well

 

Pardon my ignorance, is there a way to just check the R/R to see if it's good?

I pulled the rectifier off today. I noticed on the bike plug, if you have the push tab facing up, the top right connector is all burned up. I'm guessing this could be the issue. How did it happen and how is it remedied?

+1 for the link to the Triumph site/ rectifier upgrade How-To! That's the best thing ever! I did it and it works! Found a 2008 R1 rectifier on ebay from a bike with 4k miles. Got it shipped to the house for like $82. Installed it and my 1991 f2 runs again! If I was any more excited I'd be wearing a condom!

 

Hey guys, I was just going through these problems. My R/R was overcharging and killing batteries left and right. I bought a R/R off of Ebay from Rmstator for$63 and it's heavy-duty and done the job well.

 

What is that little black circle thing mounted on the aluminum plate beside the stock RR. Did you guys remove it altogether. And how did you mount the Suzuki RR flat. Or does it need to be flat?
