With the truck running what is the voltage at the battery posts? How are the connections? Grounds?

may i ask..is it your stock dash guage thats telling you low?? or do you have some other instrument telling you that?
at Idle are your lights dim? but when you increase engine rpm the lights go bright? if your engine is idling at the proper rpm, have you changed any pullys?..the standard alternator must turn at least 1800 rpm at an idle for most of its output Re-pully ratio's

Fire prone 2G alternator? Or have you converted to a 3G?

Great Question Timber...as an electrician...i will tell you this.....when the engineers designed that connection on the 2-G...They took..at least 4 tokes too many...
I would like to add...on top of that..probably a good percentage of burn-outs are occurring from the MIS-Use of Dielectric compounds
