1995 Chevrolet Alternator Failures
Suggested Repair
With all accessories off, disconnect the battery positive cable and connect a 12-volt test lamp between the battery positive post and that cable. A full-bright lamp indicates a short. Locate it by pulling and wiggling wires and harnesses while watching the lamp, starting in the engine compartment where some circuits may be unfused. Inspect any electrical work done after the problem began first.
Conversation Summary
The owner of a 1995 Chevrolet half-ton 4x4 has replaced the alternator three times in six months and also replaced the battery. After the latest replacement, the lights dimmed and the heater fan fluctuated within a few days. The expert suspects an unfused short and recommends a test-lamp check to confirm it, then tracing the short by moving wiring, beginning in the engine compartment and checking recent electrical work.
