The Ford solenoid takes much less current than a starter trigger...

I get a weak click with a hot engine, followed by the screeching/grinding but no engagement (not always). I was going to mention the hot engine variable... I was wondering about the start trigger wire supplying enough amps to the pull-in windings. I have a dc solid state relay (ssr) that I can use to switch the current ( I measured 11 amps) and just use the starter trigger as a low level signal. That should improve the hot start issue.
To improve the pull-in / motor start timing issue I fabricated a .090" stainless shim that slips into the nylon link:

I am also making a new 2/O cable from the front battery post (battery moved to trunk) to the starter to minimize voltage sag under load.
