What would be causing starter buttons to burn up? Got negative to ground, positive to one side of starter button and starter cable on the other side of the button. That's how it was when I got the tractor and seemed to work fine until one day it was cranking hard and seemed like either the battery was weak or the starter wasn't engaging all the way. I took the starter off and tested it with the battery charger. Bendix didn't seem to kick out all the way, so I swapped the starter with one that seemed to work alright. I put it in, tried starting it, and it didn't even wanna try. So, I ran a test light on both sides of the button. The side to the battery lit up fine, but the other side when I push the button barely lights up and makes the switch smoke. I'm obviously not getting enough power through the switches somehow. I've tried 4 different switches on it plus bench tested their resistance. Two were junk, one was sporadic and the new one was obviously good, but not letting the power completely through. Not sure what else would be the problem other than a bunch of junk switches.
