Out of curiosity, if an inline fuse was put on the power line for the aux water pump, sould that cause a problem?

For example, if my inline pump was disconnected (from a bad fuse connection), would that cause trouble? As I understand it, the power line for the aux pump is connected to the ACC (thus the reason for the inline fuse, so that if the pump goes bad, it doesnt fry the acc). If that had something to do with it, and then the acc forces the monovalve open, then the system has water flowing through due to the engine water pump flow, making heat. Feasible?

Ill check out the monovalve ASAP. The only thing that can be checked/replaced is the monovalve insert, sold as the /monovalve repair kit', right (the part that is under the four screws, that pulls out from the housing)? Or do I have to remove the whole assembly with heater hoses attached, etc.?

Thanks,

JMH
