Refrig. won't work on 12V or AC

[mccammonds]

The Frig. works good on propane but will not work on 12V or AC

Does anyone know of a source for an original coach  wiring diagram for my 1975 521F?

Without the schematic available the basic questions need to have been answered.  The simple ones are, is the unit plugged in?  Is the switch set to electric?  If all these have been satisfied, then you might want to look at the switch itself.

Thanks for the input.   We've been on the road for four days and just arrived at our lot in Benson, AZ.  Will get the meter out and start running the voltages down.  We just bought this rig and we're on our maiden trip so to speak.  So far I've heard no noises that alarmed me.  But with a 32 year old rig anything can happen.   Wanted to take it across the border at Algodones to have the AC charged with R12 but our paper work is not complete as far as tagging it.

Wow!  Pretty adventurous!  Our maiden voyage will be a whopping 80 miles from the house!  Good luck and keep us informed on what you find.

Checked the 12v and AC into the terminal blocks and through the switch.
On the left side of the Heater coil I have voltage.  But,  No continuity across the heater filaments when I opened the circuit.
Does any one know if they still sell heater elements for a Dometic RM 66??

Not to change the subject, but as far as the AC goes, just add or change to 134  I do it all the time in my shop with no problems. All that retro fit stuff is probably developed to sell parts. Mine works great.

If you have the same model as mine RM66 the switch is inside down at the bottom panel.
It it the one that says   GAS  turn it and it says 12v turn it and it says elec.
