Help with electrical please

[zulu52]

Hello,
I have a 2008 Northstar Arrow 8.5.
The last time I had it out was for a 6200 mile trip in 42 days.
Everything worked fine.
That was 10 months ago.

I was just checking things out today and am having trouble. I consider myself a pretty good do it your selfer.

Except for anything electrical. My downfall.

I am plugged into shore power full time at home. I check the battery for water often.
Today I had no power and a very weak battery.
Finally figured out it was the socket. Plugged into a different socket with a 100' #10 extension cord. I know 100' is pretty long.

Now the A/C comes on and is running well.
Refrigerator flashes on and shuts off.
Happijacks won't work at all.
Microwave works.

Every time there is a voltage change, like turning on a light, the gas alarm sounds, then goes off. Propane has been shut off for 10 months.

I don't have any idea how to even trouble shoot this.
Any ideas?
Thanks,
Zulu

I would start by putting a charger on the battery- my money is on bad converter, as most modern converters would power the rig even with a bad battery.

It sounds like your battery and/or +12V converter is out.

Propane alarm always make beep when voltage goes low.
100' #16 cord might be good for charger, fridge and lights, but don't run AC and micro on it.
To run those you'd need #10 cord, or shorter one.
Jacks take lot of current.
I can run single one on converter power, but when I try 4- the breaker goes off and I have to wait for it to reset. Meaning for camper loading, I need good battery regardless shore power.
Bottom line, you need good battery to start.

There is voltage drop in a 100 foot run even with 10 gauge wire.
Sometimes batteries do not do well on a charger for long periods without any discharge.

take the battery to have it load tested at any auto store.

And don't run the A/C on a 100' extension cord.
