I put a diesel engine in my 2510 (it was gas originally). The starter would hardly crank at all. Figured it was because it was the gas starter so I put a rebuilt diesel starter on. Tried and still have the same issue.
When I first turn the key on, the dash warning lights come on. I push the starter button, I get a click, then the dash lights go out and then nothing. After a while it'll let me try again, but with same results. Figure its the circuit breaker tripping.
I had gotten the wires hot when I put 1 alternator wire on wrong. A few wires in the switch wiring harness looked semi-
melted. All the wiring is original anyway, figure why not and I replaced the switch harness, key switch and circuit breaker. I cleaned up the connections at all these points too.
Tried again today after replacing all that and get exact same result.
Turn on key, warning lights on, hit starter button, get a click at the starter then dash lights off and can't try anymore for a while, like the breaker tripped.
What do I check next? I'm stumped.
