Replaced house batteries/no power

Good news, glad things are working correctly,
Yeah we miss going to Q, that was Our only winter time camping/travelling , I'm surprised it will be happening this year, enjoy it, and have fun, be safe
I wish we could go and be there to enjoy it

Yay. Glad you guys got it working.

UPDATE: After checking everything over and over we still could not get the inverter stay running. On one final check of power hooked the ground cable up to the large bolt under the the key switch that shuts off the ground to the batteries and wham inverter turns on lights in cabinet come on etc. Yes the ground key switch was not making a good contact :S We are back and running properly and will be headed to AZ next week !!

Thank you for trying to help.
(George it's the all in one Magnum inverter. Yep I've turned on the hair dryer with a heater running at the same time LOL Pop goes the fuse) Miss seeing you in Q.

Is this an Inverter_charger combo unit, or separate stand alone inverter,
Does inverter supply 120vac to the whole RV or just a few dedicated circuits
If this a Separate inverter powering the whole RV,
Do you have any portable electric heaters plugged in, anything that could be drawing a really high amp (power watts) load on the inverter
My ,2000w inverter pure sinewave inverter, will run my MW, powerMax 75 amp converter, or a portable electric heater, but not enough batteries for a long run, voltage Drop means high amps, which heats up the DC circuit breaker , then it trips,
I only forgot and did the electric heater on inverter battery power ONE time, that was enough, I have forgot to turn off the converter power circuit several times, when switching from generator to invereter here, in this Bounder, the Safari was wired with only dedicated circuits kitchen and entertainment to inverter,
I installed this inverter, here in the Bounder, and connected it to power all outlets etc..
Power going to converter must be shut off before turning on inverter, if I forget to turn off circuit breaker for my 75 amp converter when switching from generator to inverter,
After a about 20 minutes the DC amps load feeding the inverter to . Power the converter from the inverter THE breaker will be hot and trip,

Are all connections clean and tight?

OP stated it took several minutes for the click. Perhaps something is detecting a problem and times out? I'd expect reverse polarity and shorts to be rather quick.

OP Can you determine where the click is coming from?

Pass through relay in inverter is throwing a hissy fit.

I'm guessing the inverter is hooked up backwards.

There is a better way to connect the batteries.

However, what is there ought to work.

Battery banks often have an automatic circuit breaker. They do have a finite life span. Some use a manual reset with a little button.

The diagram is correct. Now the question is did he hook 'em up properly

This is where the voltmeter (which indicates polarity) is of great value.

Hands off that's as far as I can assist.
