So, it seems to me that the reason the Pro Power is shutting off during rain, snow or right after a car wash is there is a ground that is exposed to and shorting out. Does anyone have a diagram that shows the grounding location for the Pro Power harness?

I thought Ford claims it to be a “software” problem?

I believe that the ground "shorting" to the frame because of water intrusion somewhere is not what's going on. The Ground of the Pro-Power system is already connected to the truck's frame. Hence I beieve that the gound being seen is water intrusion (if it is a water problem) between the "hot wire" (red or black) and neutral (white) or ground (green). Note that the neutral and ground wires are bonded together in the PowerBoost's Propower system.

If I remember correctly, the propower is completely isolated from the chassis. No grounds or neutrals are bonded to the frame.

Either way, the only way it should short is the water getting between the hot wire and a ground.

I don't agree. From a safety standpoint it doens't make sense to completely isolate the frame from the generator. The whole purpose of the grounding is to provide an electrical path that will keep a person from electrocution when a fault occurs. Isolating the frame denies this path.

I'll let you know. It was clearly indicated in the FSM exactly how it was all wired up.

If the AC inverter was bonded to chassis ground and there was a fault that sent AC current/voltage to the DC system, that would probably be bad. To me, it would make sense to have it isolated. Especially in the event of an accident so first responders don't get electrocuted.
