Converted a 1995 gm pickup into a top drive last year, all worked as planned except two flaws that I need help on. 1st one should have been simple, got drawing of ignition wiring on the steering column, just like GM has done for years, Red, Pinks and purple wires going thru plug into factory column/switch. So after ignition comes out of column I took it to a continous duty solenoid 50 amp, and then back into wiring harness, I also took from +12v going into column attached to that intermitent solenoid and back to Purple wire for starter. The plan was you would have to turn key on in cab for security reasons and could start from up top or in cab. Twice in less than 2 months using it, the starter solenoid smoked and once the continous solenoid ????
