Re: (ET) Dead E-15
Right - there should be no electrical connections to chassis. There are
a few common places that it can occur, over time with wear and tear; the
mower deck, the wires going past the drive pulley, the lift motor ( I
think), where else?
If it only happens in one place it's generally not too big a deal, but
if you get two --- strange things start to happen, so it's good to check
for chassis connections every now and then and fix them. I guess since
most voltmeters today are very sensitive we should also differentiate
between high and low resistance chassis 'shorts'. A high resistance
'short' could be some carbon dust in the motor and won't cause a big
problem, but a real short (like a pinched wire) is a problem. A 36V
light bulb would handy to gauge the problem.

measure a voltage to the chassis, you have a problem somewhere.
Hopefully someone will correct me if I'm off base (not unusual)

Check that the lights work
Critical path for all the symptoms you describe:
1. CB1 (as already suggested)
2. Check the fuses (firewall, under the hood) - pull them and check for
If these are good the 'fuel' gauge should function
If the gauge works but still no go:
1. Check that the leads didn't come off the seat switch and brake switch
2. Be sure the brake is off!
You should also investigate the chassis ground:
1. Check for voltage to ground with deck unplugged
