7V Regulator Melting

Post by LouGrab » Fri May 11, 2018 11:39 am



Fixing up my 82 and replacing parts that are probably going to fail while I'm in there. So I got the gauge regulator off this site and it seemed to be working before I started test drives. It made it through 1 before it died. Looked into it and it is getting hot and turning the black stuff inside to goo. The goo oozes out of the casing and the electronics are loose inside.

Wondering if this was a defective unit or a wiring issue.

Thanks,
Louis

I was just about to order one of those units for a 1980 GL1100.

If the gauges operate normally it could hardly be anything else but the regulator itself.

We have had this happen once before (out of thousands sold), and it was a user who installed the regulator incorrectly, and was shorting the output to ground. It indicates that the regulator is being overloaded, and it is getting so hot that it is melting the potting material.

It means that there is either a short, or a wiring problem, and too much current is being drawn. Under normal operation, the current being drawn is much less than 1 amp. If the regulator is installed correctly, then your fuel or temp meters are drawing so much current that it is melting the regulator potting, then you definitely have a problem. Fix the problem with the meter/sensor, and the regulator will operate normally.

Thank you much, that was it. Hooked it into a better ground and the gauges perked back up.
