Phantom draw

I have a 2003 30' Georgetown MH

I just checked my house battery for any amp draws. I discovered with my voltage meter that I am using 0.7 amps, whether I have the power shutoff switch on or off.

Is this amp draw normal ?
If not how can it be drawing anything if I have the power shutoff switch on.

I don't know what is normal, but on another post, some said that Motor homes have a gas detector, and an "auto gas shut-off" valve that draw power all the time. These are wired in a way that they bypass the disconnect switch. If you have an electric awning, this may also bypass the disconnect switch. You could always hook up your ammeter and start pulling fuses to you find it, or them.

Phantom Draws

So the gas detector has a draw even when the disconnect switch is turned off.

I can't even tell if the gas detector is working, Right now it is set to off. It is interesting that when it is at the off position it also indicates that it is also in the "test" position.

I wished I knew how this detector is supposed to work, because putting it at test/off position does nothing.

The MH never came with a manual or instructions for it.

RDjensen, The gas detector is wired directly to your battery so regardless of the disconnect it is always on. Your power steps (if so equipped) are also wired direclty to the batteries. However in my testing the detector is only good for about .1 amps of draw, your meter probably another .1. I have noticed an amperage draw of up to .7 or .9 in the past when the rig is at rest but it is intermitant and so far unexplainable. Usually mine will settle down to about .1 draw with the disconnect off.

My battery switch was installed by me and it disconnects the
battery from everything period.

As suggested-- try pulling fuses until you have them all out.
Do you still have the phantom draw?

.7 amps is a big drain and 24/7 won't take long to suck your batteries
dead. Last resort is add your own disconnect at the batteries.
But I have a trailer and my LP tanks are outside and shut off
at the valves when it's in storage so no worries about a gas leak.

My biggest phantom draw was my onboard power center charger
itself. Donno if yours is disconnected by your battery switch or not.

Good Luck!

Phantom Draw

Thanks a lot for your responses.

If my gas meter should only use .1 amp then I still have .6 draining from somewhere else. Like KyDan said it won't take long to drain my two six volt batteries.

I can try taking out the fuses, but wouldn't everything with a fuse go through the disconnect switch?

On the Georgetown there are fuses under the step and some in the back of the bedroom. Should I check them all?

You bet. Dan has a good plan, start pulling fuses one at a time. I would start with the ones in the back of the motorhome. The ones under your step should be for the slides and you will have separate ones for the LPG detector and steps which are inline types on the power cord for each item.

Let us know what you find. I'm curious.
