2005 Camelot, 12V goes out intermittently, ??? CHANGE OUT INVERTER ???
 
Hi All,

we have a 2005 Monaco Camelot.

The 12V system is going out intermittently (complete loss of 12V power, AC is fine). We are plugged in continuously for many months.

When I checked this morning, the 12V was out. Several hours later it healed itself, and turned back on, all by itself. It is on right now.

Over the past few weeks, I started to notice that the water pump was turned off, which it does when the power goes out, and then turns back on (the water pump stays off). So my initial reaction is, it is getting worse. TIME TO FIX IT.

So, I'm thinking of just changing out the Xantrex RV2012 Inverter/Charger.

But, As I have learned over and over, best to get forum advise.

So, if changing it out is best, Change it out with what make/model Inverter/Charter (I like to do it myself).

So, if no change out, what next ????

!!! Thanks In Advance !!!!

Most likely Bigboy solenoid.

Donít know if I would go there first. Loose wires, thermal cycling on a relay and if itís like mine there are at least a couple of relays involved in the 12 volt system. If you can get a schematic of that system it would help. 1 troubleshooting approach is if you find a component that you suspect and you know it should be closed then jump around it and see if the problem clears. Replacing a inverter would be the expensive way to troubleshoot

so, the Bigboy solenoid is separate unit located in the side electrical compartment, and not a part of the Xantrex RV2012 Inverter/Charger ???

We, of course, have a manual perko switch to turn off the 12V system (duh).

I would like to fix this before it fails for good, as we are currently located in an area with minimal local parts, so everything is likely internet order.

I have had to replace Inverter/Charger's before in other rv's. Just seems like a 16 year old Inverter/Charger has lived it's useful life, but perhaps not.

I'd check the perko, battery disconnect switch ("salesman" switch--sorry Twinboats, I couldn't resist), and battery connections before I threw $1500-2000 at a inverter/charger.

Not the big boy, that jumps between the house and chassis battery.

Your 12 volt power is going on and off, that's not the inverter/charger. If it was that, the batteries would slowly go dead, not switch off then on in short order.

Have you checked your batteries? Water levels etc. Some converters need the batteries to be good to work right.

They don't call the Perko switch a " Salesmen switch ". Perko switchs are manual turn, master battery disconnect switchs.

What's called the "Salesman switch " is the small switch near the door that operates the battery disconnect latching relay.

See what happens when you use names of things not labeled as such.

The latching relay may be failing. You need to be there when the power goes out and switch that battery disconnect switch, near the entrance, off and on, to see if it gets the power back on. Then suspect the latching relay.

I wasn't very clear but I was also poking at you. I have a rotary dial battery cut off switch by the batteries, not Perko brand, but same concept. Mine failed years ago and I replaced both the chassis and house battery switch. If he has a battery disconnect switch up by front door, it very well could be the relay that is controlled by that switch failing or being intermittent, but that has nothing to do with the Perko switch.

and I do agree with you about not using the term "Salesman switch". It's misleading for many.

Bob&Sofi --

Does your coach have the Multiplex Lighting System -- If so, your problem may be in that system -- It`s very complicated -- Open your AC load center & see if there`s a flat piece of plastic, about 4 inches long, laying horizontal under the breakers with black wires going to it -- That could be where your problem lies -- Bill Willard

Find the house battery disconnect relay. Move big cables to same lug to bypass temporarily ,see if solves issue.
