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,
If not already done, get and install an APC from Mr. ERF. Then, if that doesn't fix it, post back here. http://gmcmotorhome.info/APC.html
