Re: (ET) HELP

Thanks to Tom Kuffa I was able to swap out the broken bakelite 1A 
contactor.  Put a new 20amp fuse in the block, engaged the power switch, 
put the transmission in neutral and pushed the pedal down slowly.  The 
motor started right up in position one.  Continued pushing and the fuse 
opened with a flash.  Rechecked my install against the schematic and 
everything appears OK.  Put in another fuse... Same thing.  The fuse opens 
in the second speed microswitch.

Being as I had cooked the terminal off the heavy 1A power wire could I 
have arc/fused/damaged something else that would cause this short?

What are the recommended troubleshooting steps?

Thanks in advance,

Bob Klein

If this is the 1A, you could just wire both of the big wires to one of 
the studs, which would basically bypass the thing. Not perfect, but will 
get the tractor running.
