Q: Stalling headlights blower on. 1986 Chevrolet K10

asked by on September 01, 2016

When my truck was under load with my headlights and the blower on it will stall. It lost all radio presets and everything else. I have replaced the battery, alternator, starter, ignition switch, wiring from the battery to the starter and the starter to the alternator. I have also replaced all the wiring in the air conditioner, heater, electronics, resister and relay, blower motor, and the headlight switch was replaced, too. Do you have any bright ideas or suggestions?
