Strip the ends of the housing and both end plates where they touch each other, down to bare metal. NEVER paint components before assembly- - - -it's just cosmetics and a quick spritz with a rattle can after everything is bolted together is all you need. No wonder it won't work- - - -you've insulated all the parts from each other. The total resistance in a good starter circuit is less than 1/10 Ohm- - - - -almost a dead short.

Cringe and wail in fear, Eloi- - - - -we Morlocks are on the hunt!
There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self. - Ernest Hemingway
