DC electrical circuit

[PDMcCripe@...]

Greetings all,

We recently began to experience intermittent failure of the old Dometic RM 3804 refrigerator, indicative of an impending circuit board replacement or repair. However, the problem has compounded in as much as I discovered also the failure of the essential DC electrical power to the rear of the refrigerator. Replacing the power source with an external 12 vdc battery restored operation to the refrigerator. I'm unable to locate the fuse or other protective device for that circuit in either the forward electrical bay or in any overhead compartments. Does anyone have an idea where this seemingly easy-to-find item would reside in a 1991 year/model PT40?

Also, back in September and October I was searching for replacement faucet cartridges for my shower/tub. All the responses I received referred me to Moen. Moen however has denied ownership of the design I presented them in a photograph, pointing out that Moen is plastic and my cartridge is all-metal. I'm still searching. I can't declare with certainty that what I'm trying to replace was an original part and it bears no manufacturer's name or number. This particular installation is somewhat difficult to access by any approach other than destructive.

Heading for Quartzsite in a week to join the Southwest Bluebirds and will continue the search there.
