Re: Scott's 1972 Chevy K-20. A place to start.

Ok... color me perplexed right now...

So, after diagnosing some issues, I realize that I had mis-wired my FSS. Wanting to do it properly this time, I went ahead and got a relay, setting it up as directed in the diagram below:


When set up, I don't have any issues with the relay pulling the FSS, and the regular power holding it up. However, I have found that when it is working through the relay that there isn't enough juice going through the relay to actually crank the starter. To be certain, I changed the 85/86 and ran both combinations. In both situations, when I start the engine, I can hear the FSS pull, and it'll hold until I shut the engine off. And in both cases, the starter won't crank.

When I go back through and bypass the relay for the starter, it kicks over with no issues. The relay is 12-14v & 30 Amps, so I'm thinking that it should be strong enough...

Any thoughts?

The only other idea I have is to go back and hard-tie the pull line directly to the starter.

(Oh, and for the stupid trick of the evening, the cause of me going back to this is that I found I had my pull and hold lines backwards.)
