labrat Posted June 19, 2007 Share Posted June 19, 2007 This isn't my Z, its my newest donor, but i have gone through 3 ignition switches today. 78 el camino. 350/th350 I took off the intake manifold to change out the lifters (had a wicked tap), so as I was putting things together and timing the motor, (stabbing dizzy) bumping the starter to turn the motor to get close to TDC, i bump three times then nothing. No fourth bump. won't do it. also have no radio, guages, b+ to dizzy, nothing that comes on with ignition. Replace ignition switch, check for shorts, figure the choke wire was loose and grounding out or something. Lights/guages come on for 5 secs then die. Buy another ignition switch, check VERY CAREFULLY for shorts in the work from where I had intake off... new ignition switch lasts 30 seconds. What is the best way to figure out which circuit is causing the problem without burning up $20.00 ignition switches that aren't that easy to swap? Could the starter solenoid possibly be shorted out, drawing too much current when I start the car, smoking the switch? same question, only electric choke on edelbrock 750cfm carb? Any thoughts, random or on topic, are appreciated. Sorry if I come through as a Quote Link to comment Share on other sites More sharing options...
