Hey I have a 1980 Gold Wing, 47,000 miles. Off of cold start, the amp meter reads output at around 13.75 volts, Then after running down the road for about 4 minutes, the output goes down to a little under 12 volts. ?Is this a stator problem or is it possible a diode in the regulator stops working once it is warmed up. ? Is it possible the stator is not working on all outputs legs. Any help would be greatly appreciated.

Thank's RT

RT, it could be a sign of a bad stator, or resistance in the wiring, or a rectifier going out, or ?..


You didn't give the engineRPM's that you were getting low voltage at but low at base idle is NORMAL.. If your your voltage is under 13 going down the road at speed then you definitely have some charging issues..

Start by verifying the battery is full of water ( a low battery can cause some strange readings)..

Then put a voltmeter DIRECTLY on the battery posts & monitor the ACTUAL battery's voltage (if your present meter is monitoring at the fuse box or away from the battery it could be showing the wire harness voltage & that could be skewed from wire or ign switch resistance..

If your voltage is actually that low at the battery then you really need to run a stator test using a small volt meter.

Look closely at the 3 yellow wire connector (just in front of the battery), if it's burnt, discolored, or the wire terminals are discolored-- Then cut it out, then cut the wires back to CLEAN wire the solder the wires directly together & cover individually with heat shrink tubing.

A simple rule is,"Resistance increases heat, Heat increases resistance." Using this as simple truth, I would strongly suspect a marginal connection somewhere. If your charging begins at 13.75, your stator is PROBABLY good. Clean and inspect every connection. Hardwire you stator. Do as Twisty suggests. It also is a good idea to check every ground connection as they can also cause high resistance failures. Good luck and let us know how it goes.
