We went after the ground first and did find some wiring that needed to freshened up so that is done.
I have a heavy cable (welding cable) going to the started.
It's going to get a heat shield today. I have the mazzaloni headers
Haven't tried the pickup idea. I'll try that today also
I know you have a big enough wire for the positive, but how big is the ground wire? That was my problem, from what Ive read, the negative needs to be as big. After I went with a bigger ground wire, mine starts right up, hot or cold.
