Installed the APC that Gene sent me but my Alt light still glows. (perhaps a little brighter than what I would call a Glow.)

I have a good Battery/Charging System Tester and it tells me that my Batteries and Charging System is working properly.
My Alternator is putting out 14.5v at 1500 RPM. I do have 2 6V Trojans as house batteries, could this be the problem?
Any ideas?

is that your reading at the alternator or off the isolator?

Yes Gene, checked the fuse, it is a Sfe 4.
Will attempt to check the voltage at the lamp.

Sorry for the delay, it is at the Battery. The Tester hooks to the Battery and reads from it.

BTW, all seems to be ok now that I removed and replaced the SFE4 Instrument fuse. It may well have been corroded after all these years and not making contact.

SFE and AGC fuseholders and fuses are notorious for that!
