When my truck is running I hear a clicking sound coming from the drivers side of the camper, is that the system recharging the house battery?

[Stan@FourWheel]

Most likely your camper batteries are really really low. Best to plug the camper in overnight. And recharge from shore power. Leaving the master kill switch pulled out (on). Otherwise the camper battery(s) might not recharge on their own.

That’s your system “trying “ to charge the house batteries.

The stock isolator can’t handle a deeply discharged house battery. Stan’s suggestion is a great short term fix. longer term is upgraded wiring between the truck and camper and a better isolator, like the Blue Sea 7622

Gracie, always good advice from the team here at WTW

To be clear here, you are hearing the battery isolator click. As Vic Harder suggests, many are improving the system.

BTW, I'm running 8 gauge to the system from the truck, do you guys not think thats enough?

[Vic Harder]

i used 2g.  That's likely overkill.  4 g has worked well for others, and is what i would use next time.  6 g should be ok, 8g seems a little thin, but check the voltage loss with the expected current dump ...

 

You MAY be totally fine w 8g and a better isolator.

It can be becuase of camper batteries being low. Try changing the camper.

I am having the same problem. I have 2 115 amp 12v batteries and a sure power 1314a battery isolator. I think it’s 6 gauge wire I ran from my battery. I am finding that when I disconnect 1 battery in my camper, the isolator works as it’s supposed to and stays connected, but when I reconnect my second battery it starts disconnecting. Anyone else have an idea?

Test your second battery it could be bad or low voltage and drawing down the first battery.
