gravely 12-G
Hi all,
I picked up an old gravely 12-G with I think the 12 hp Kohler for free and when I got it the key didn't engage the solenoid but I figured that out, but now I can't figure out why after I turn the key to run the ignition relay disengages and the it dies. I have tried a known working key switch and it still did the same thing. I have bypassed the seat safety switch and all the other safety switches are working as they should.

does anyone have any ideas on what the problem could be?

Get a L - O - N - G jumper wire, with clips at both ends.

Connect the positive of the battery to the ignition coil.

Now crank it,, if the engine stays running, you have not found all the safety switches.
The other possibility (and this happens a LOT) is that the ignition switch is bad.

Fix it, or simply use it with the long jumper wire,,,,,,,,,,,,,,,,,,, :eek: o_O

Not sure exactly how to fix the current problem, but one thing that was weird on my 12 hp Gravely that I had you need to know.

If the points are set at the (think it was) 0.016", they will never close. Therefore, it will not run. You have to set about 0.012 to 0.014".

Does it have a mower deck on it. If so, how does it engage and disengage from the engine.

Tractor Data doesn't show the Kohler model number, can you post it here ?

Ok that's a start. This from the engine specs:
Ignition system Magneto or battery or breakerless ignition system
What electrical Ignition system does your engine have ?

It has a battery ignition, with points, and condenser.
The ignition switch eliminates power from going to the coil.

This is my 2 wheel version of the 12G,,,
