At my wits end on this.
My 1984 B6100 HST has no electrical power. No starter, no glow plugs, no hour meter, no lights, nothing at all.
I was mowing with it and one of the pullys on my deck messed up and I shut it down. 2 minutes later, I got on and...nothing happened when I hit the key.
Long story short, new battery, new ground, new ignition. Checking with a circuit tester, I have power to the starter, power to the ignition switch, power to several wires I have tested. Just nothing works. Turn the key and no starter or glow plugs. Leave the key on and no hour meter.
Please don't tell me to check the main fuse. I don't see that this model has one, unless it's built into the ignition switch.

I would greatly appreciate and ideas you may have.
Regards,
Bruce
