180 fisherman with 235 ??

[phatdaddy]

take a 6 gallon portable tank and hook it to the motor
run WOT
if it runs out of gas in 15 minutes or less, its a 235.

as far as wiring, like ferm said, i'd cut it all out(except engine) and start over. when your through it will be a mess, but it will be your mess.
