I have a 95 ford f150. I can have it running but when I turn on the headlights my truck dies. I had the battery and alternator check and they are good. Can you help
Possible cross circuit in the headlight circuit, low voltage to and or from the fuse link connections, bad grounds, just few things to check.
Clean and tighten all battery connections. Also do the negative connections on the frame and motor.
