Help house battery draw down

[Tightline]

2017 Grayhawk 31ds. Purchased from Northside re on June 9th. Been planning trip out west for several months. Leaving Monday morning. Just found out I have a drain on house battery . When fridge is on over night not plugged into power, house battery voltage will drop where fridge will code low voltage before the next morning and be shut off. Have pulled every fuse on house and still have slight draw on negative post of battery on test light. Have traced it to equalizer system short. Don't know how to check wires or system for short. Has anyone had this issue, or any advice. Again leaving this Monday morning. Call or text because I will be trying to figure this thing out. 606-316-9900 Thanks for any help

No, just norcold gas,or elec

Automatic levers?
I believe I read somewhere that the circuit board is active all the time?

Fridge on GAS?

Has your battery ever been discharged to a very low voltage before? Like below 10.5VDC? Or totally DEAD ("0"VDC)?

Thanks Grumpy, if I understand the control for leveler sis on chassis circuit not house? When remove neg lead on house battery and hook up test light only thing up is leveler panel and it beeps and power light and all four lights indicating jack are down flash only when ground is touched with test light showing very dim and blinking same as control lights.

Do you have a volt/ohm meter that you can use?

One thing i did was to add one of these 400AMP AC or DC clamp-on AMP METER to my tool box...

I use this Sears Craftsman model 82369 from AMAZON...

This is very useful for clamping around the battery cables and reading what DC current is being pulled.

From experience I know if my battery is constantly showing 6-8AMPS DC CURRENT drain is happening that my battery is not going to last very long doing this for long periods of time...

When reading the DC CURRENT draw you can then go pull each on the DC fuses one at a time and see which 12VDC circuit is the cause of this drain.

I also keep a close eye on DC Battery voltage at all times. I know when it reaches 12.0VDC charge state that it is approximately at its 50% charge state. I work very hard at not ever letting my batteries drop below this level. When I see this happen I will disconnect my batteries and wait for the opportune time to fire up my 2KW Generator and do a three hour battery charge to get my battery bank up to its 90% charge state..

This is all normal routine maintenance for us when camping off-grid somewhere. It's not much fun when you lose your batteries at 9-10PM and have to wait until 8AM the next morning to be able to use your generator to recharge the batteries.

Are you sure your House Battery is good? I have a 2017 and mine was bad from the start and had to be replaced. If there is only a very slight draw on your battery, it should not go down overnight. I'n not there and do not know all of the facts, but after what you said you have done, I would look hard at the House Battery.
