HELP with Alternator/charging system question...

[LOHRTBT]

Is there anything that would keep the electrical system from charging properly?
other than the alternator, or battery?

Yes my voltage reg is in the alt... Getting mine rebuilt, in the mean time, the one that O'Reilly gave me will not charge the battery...it just runs down...we checked it with another battery to eliminate the possibility of bad batt. and the voltage is not where it should be...about 12.4 volts and when lights are turned on, down to 11 and more with the stereo...it never recovers even when the gas pedal is depressed.

We even took it back off and had them test the rebuilt unit..it tested fine...unless its just the wrong one for my truck... I dunno. Getting my chrome one rebuilt today and having it turned into a 100AMP instead of 60 so hopfully i can avoid the dead alt again in the future.

Could the 25volts the bad alt was pushing through the system for about 10 miles have damaged anything else to keep the system from working properly??? Thanks and sorry for the book but I wanted to include everything.

Oh yeah.... it did melt down the fuseable link wire that is off the firewall out of the wire harness...I replaced that too.
p.s..its a 1 wire alt. just like my chrome one.
