solenoid acting up
Thanks Greg for the Youtube link is good, very helpful, I'll need to watch
more of them.

I have four solar panels and felt its safer for the electrical system to be
shut down for extended periods of time.

I have to trace out some wires and figure out why my clocks and AC have no
12volt.

Thanks Michael

Wanderlodges have so many different fuse/breaker panels and use a mix of
protective devises from the self resetting breakers to glass fuses. In your
bedroom panels make shure you check to see if your getting 12 volt power past
all of your breakers and fuses. Also does your coach have two 12 volt power main
shut off switchs? On my PT40 one of the main 12 volt shut off switchs is in an
overhead living room cabinet and it shuts off power to the front and rear clocks
and a few other things, you may want to also check that shut off if you have it.

solenoid acting up
Those giant solenoids will occasionally blow up inside and have a carbon track leak on the main terminals. Remove all wired from it. Check for a few hundred Ohms resistance on the coil leads. An infinite reading from the coil leads to the case and infinite from the main pins to each other, the case and coil wires. If you get a few hundred KOhms, the solenoid is leaking and will get worse or eventually catch fire. Also, Activate the solenoid and read ZERO Ohms main pin to main pin to show there is no pitting or burning on the main contact surfaces

Wayne



I may have not worded my question right---



I am having trouble with the Anti/Theft switch on my dash that controls a

solenoid/relay in the lower generator fan bay. It is a 200 Amp sp st

Cutler-Hammer solenoid that when turned off still has 3 or 4 volts running

thought it to the dash. When that happens my step extend switch light flitters

and some switch chatters and will only completely shut off when I activate another switch

like the heated mirrors that has a large draw.



When the cable is disconnected and a meter is attached the solenoid works

every time showing 12vdc and "o" or .01 vdc when off.



The solenoid either has feedback? or is broken? A friend has suggested a bad ground but do not know how to go about finding one.. I've been looking and checking for bad fuses and trying to get a understanding of schematics ----- but no luck yet



Also I seem to be missing the key for the relays in the front panel they are numbered and on my schematic but not described.



A new Cutler- Hammer solenoid is 200$ and it may not be the problem



I have 3 other components that are not working and may or may not be connected or caused by the low voltage/solenoid problem



My upper dash clock is out, my bedroom clock and I've lost 12vdc to my rear bedroom Carrier AC unit.



I think my bedroom clock and AC unit are powered from the old Dometic control wiring harness / plug. I have not found any fuses that are out. I've purchased a circuit tester but do not really know were the lines go and read that I could hurt components that are still connected or at the other end.



Thanks for your help and I apologize for not being clearer.....



Michael
