So I have a 91 dodge w150 and I've been trying to get it to start. The starter relay at the time had 12v bat and 12v ignition. The other wire coming in is neutral switch wire. Well no luck so I just bypassed the relay with screwdriver and it will kick p Over but not fire....well after hours of trying now I got big problem. The only time I got 12v ignition power is with headlight switch on or horn button pressed...my buddy was laughing at this...could the ignition switch gone bad?
I got it narrowed down to ignition switch circuit. I got 12v to switch but soon as I turn key forward I got nothing coming from yellow wire and I lose 12v battery red....strange
