Chonic Alternator Failure

something is shorting somewhere... or spiking the alternator.

1. make sure everything is properly grounded. (alternator included, VR, engine block grounds to firewall, etc.)

2. it could be your blower motor or A/C components... even headlights.

3. check the entire system for bare wires touching ground, or corroded/tarnished connections. a tiny piece of emery cloth on connectors can do wonders.

4. headlight harness is a likely candidate also. it's very likely that the connectors need maintenance badly. again clean all of those connectors as best as you can.
