regulator/rectifier

Postby jasonm » Sun Aug 28, 2016 11:29 am



I'm testing my charging system on my 1982 gl1100 interstate. I'm by no means an electrician but im checking the rectifier. The wires right before the plug are getting pretty hot is that normal or is the rectifier shot? I'm still trying to understand what my manual is trying to tell me by testing the wires. voltage to battery is good its at 14.6v ,buts it later on the battery seems to loose its charge any help would be appreciated thx

ok i tested the diodes goin from green and checkin yellows was .513-.486-.496
checkin red to yellows were .513-.512-.512

So with the 2 below .5xx is this a junk rectifier? and if so is that what would cause my wires to get hot before the plug on my rectifier?

The rectifier runs hot around 165 degrees F.
Try hooking up a multimeter to your charged battery and start it while checking your voltage drop. It shouldn't drop below 11 - 11.5 v. while cranking. Anything less will point to a fried battery.
