I presumed that all the electrics governed by the main panel are fused but on further enquiry it seems that they may have circuit breakers. Is that right? The thermostat is for the freshwater cooling system.
…..I assume your 32 is the same as mine (same year!) so the main fuses are situated alongside the batteries under the starboard saloon bench. Any extra electonics should have their individual fuses, usually in-line. The fresh water thermostat is buried in the cylinder head casting; you have to remove the heat exchanger unit to get at it. That’s a rather challenging task but do-able….. Hope this helps.
….glad to help!! I’ve owned my 32 from new in 2002 so over the years I’ve got to know every inch and every wrinkle. A great yacht, I hope you enjoy yours as much as I do mine.
