Check wires! Mine somehow shorted out. The wiring harness for the engine goes behind and between the alternator and starter. I think there was a clip holding it up away from the heat because I found some plastic pieces broken back there same color/size as others. No idea what it was supposed to look like before. Anyway that part of the harness’s wires melted causing a short to either the starter or alternator. I'm still trying to figure out which one. Not easy to access! Hope this helps a little.
