Electrical gremlin exorcized

[67since67]

This is for you Mitch...I will very much abbreviate the diagnosis trail.

In 2020 I finished up what amounted to an on-frame restoration on my '67 L34/M21 El Camino. With it's Southern CA heritage the bottom side is so clean I didn't feel the need to pull the body.

With some driving an issue developed where it would occasionally shut off and instantly restart with a twist of the key. Then it became more frequent but still elusive. Process of elimination ruled out the coil and distributor. Suspected were the ignition switch, the resistance wire in the new AAW engine harness, and fuse block connections. Then it lost ignition and fried the engine harness. Now diagnosis can get serious. Pulling the yellow wire off the outside post of the starter solenoid revealed that that post is grounded.

Opening the solenoid showed that the tang off the outer post was installed on the wrong side, back side of the contact disk and making intermittent grounding of the ignition circuit. When I would engage the starter the ground was interrupted and it would fire right up.

So a new solenoid on the original starter and a new AAW engine harness, problem solved. - Bill W
