cummins
so just like the title says my engine dies as soon as i turn on the headlight...
after i turn the lights off its starts and runs perfect but if i turn them back on it dies again...
its a 2001 2500 5.9 cummins engine...
so far we have replaced the ignition switch and the headlight switch neither of which help at all....
only other problems we have had with it has been the a/c stopped working a week or two before this started happening....which i believe to be the fault of temp control cluster on the dash....everything seemed to work on the a/c when tested alone, meaning the blower motor and compressor both work when powered...the a/c isn't much of a problem but the engine dieing when i turn the lights on is a big problem....
any help is appreciated.....thanks guys..
