The main fuse on the engine is blowing the fuse and the red wire to the fuse is obviously hot too. I checked all the wiring to the tilt button on the shift lever and can not find any chaffed wires..It must be a sensor or one of the black boxes that has gone bad...Any help would be appriciated.

Is this the in-line 20 amp, 14ga. red wire? Does it blow the instant you plug it in with the key "off" or blows when you turn it (key) to the on position?
