I have an old d15, I believe it’s a 1962. The positive battery post touched and grounded the engine out…burnt the ground post off. I replaced battery end but now tractor won’t stay running. Runs for 1-2 minutes then shuts off. Any suggestions????

well with a shorted out battery cable, its probably not a fuel problem.. Electrical area... Coil , capacitor, starter key/ switch, wires...... When it dies, see if you have 12v at the COIL... if you do, then the battery / switch / key / wires are probably working right...

12v power to the coil , then check the FIRE at a spark plug.. If no SPARK, then you have a coil or capacitor or burn point problem... If you have NO POWER to the coil, then look at the key switch and the wire from the key to the coil.

--------One test is to take a jumper wire from the battery to the + terminal on the coil and then start the tractor.. That bypasses the key and wire harness to guarantee you have POWER to the coil.

Like them all, but love the "B"s.

A model D-15 gas with a generator is a POSITIVE ground. So, how can the ground short out ?? Or, do you have an alternator conversion and now it is a NEGATIVE ground ??
