Put a new motor in the AH, (glad I carry a spare) and decided to add a disconnect to the thermostats. Those wires are a *** to pull back into the case. While I was at it put a disconnect on the red wire that goes to the terminal block. It is hard to get the spade connector back on without the screw falling out. Future servicing will be to unplug two plugs, fuel lines and loosen the J bolts and pull it out.
Another thank you to Rudy for giving me some help on testing the motor while still attached. Turned out to be a flat spot on the motor.
