But last night I went to give the starter a turn again after its rebuild, and unfortunately it still didn't turn.
Things noted now that are different:
-When I push the starter button, the solenoid makes a buzzing noise. Before it would only click once. Is this indicative of the solenoid being fried? I tried to just bridge them with a screwdriver and no turning of starter.
-Still haven't bought a new battery, but I used my tractor jump starter connected to the bad battery at 200A when I tried to turn the engine over and thats when the buzzing came.
Could all of this be from a bad/no ground point behind the coils? Everything else works properly (all lights).
