Generator light on ... alternator is charging...

[alan m deluccio]

Greetings,

The 100 amp alternator on my 78 Royale is putting out 13+v, and yet the GEN light on the dash is on. The belt is tight and the connections are clean.
Has anyone had this problem? Is there a relay or??? that might be faulty ... and Where might it be located? Any help would be greatly appreciated of
course.

Thanks,

When you say 'on,' do you mean bright or dim amount of light? Different answers.

I have/had been using an APC. The light came on while it was installed. I removed it ... tightened and cleaned everything, but when removing the APC
the tab/clip on the connector on the side that connects to the alt broke off, so I have not reinstalled it.

The steering boot(s) also need replacement. There are 2 types offered at Applied. The Al Ferrara's Steering Boot Kit and the GM16-STBOOT. Does anyone
have experience with these 2 kits? Is one an easier install than the other. I changed mine out about 10 years ago and it was a pain.

Output of the alternator should be around 14.7 volts if you are reading it at the alternator or at the center post of the isolator. If read after the
isolator it should be 13.8 to 14.2 vDC.

Sign of your alternator going out. My indicator was glowing dim even with the APC cable installed . Alternator finaly died R&R'd and no more glow.

> The GEN light is DIM ...not Bright

A quick and easy check before you get too involved:
If you read down low enough on the gmcmotorhome.info links people have posted, you'll see a blurb about checking the dash lights fuse on the panel in
the glove box. Mine was blown and replacing it was the cure for me when my light did that.
