Regulator/rectifier - March 21, 2010, 08:03 AM

So I was at MFI's open house yesterday and thought I would check out the deal on parts cause my battery is shot. They tested my old battery and they said it was completely gone yet it was heating up their tester. This made them suspect either the r/r or stator was bad. I'm pretty sure a possible loose connection from my LEDs that are tapped (spliced) into my tail light wire may have something to do with it, although they've never blown a fuse during the year I've had them. My question is if I correct the short from the LED wire, is the r/r likely still damaged? In you guy's humble opinions? Thanks in advance y'all for any help.

You can bench test the rectifier with a multimeter off of the bike and test the stator once you are able to start the bike with a charged battery.

Unlikely your LED's did it. You would probably see melting wire insulation before anything else if it is a bad connection.
In response to your question: Yes.
Electronics/ electrics don't heal themselves The #1 failure of any of these devices is damaged insulation. I.E: "Letting the smoke out". Weather it be from over-current, over-voltage or physical damage, electricity traveling a path where it is not supposed to is usually the culprit.
Although, Honda's have regular problems with their r/r and stats.

thanks - March 21, 2010, 10:40 AM

Thanks Thomas and evil twin for the guidance. Just blown right now wit the start of the season and possibly having to search foot after foot of wire to find where the problem lies. Hopefully it starts and ends with the regulator. Thanks fellas
