Question about Cars & Trucks
I have a 1984 chevy c10 5.7L with a electronic distributer and the red wire on the coil keeps arching over. I have already put 4 different coils on it thinking I was getting bad coils but I really don't think that's the problem. I noticed that the coil is supposed to have a secondary grounding strap but none of the coils came with one. could that be the problem?
The strap is necessary. It is usually not replaced, so it does not come with a new coil.

does a 85 have a ECU unit ??? sounds like it could be the switching transistor thats either under the coil or inside the distributor should look like a black plastic casing with 3/4 wires running to it then to the coil look at this first as often motor runs ,stop for a quickie somewhere and jump back in and engine will not fire up ,classic symptons

well if you have checked the spark plugs and they look good then its probly the coil If the plugs have never been replaced i would start with a tune up and see if this fixes the problem. If not there is no good way for you to test it you would need a computer to hook up to the car

Try your local library for diagrams and pictures of both engines and that way you can figure out how the wiring goes
