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.
