Need to convert 24V DC to 12V DC for fridge igniter

I am installing a new dometic rm2510 in my 78 safari. The fridge requires 12v dc in order to run the auto-igniter for gas operation. I was just getting ready to hook up the Airstreams pre-wired red/white dc wires and decided to check the voltage first. It turns out they are 24v.

What is the best way reduce or split the voltage to 12 volts for the fridge igniter?

Your batteries are probably hooked up incorrectly. There is nothing that I know of in an Airstream which requires 24V.

You should get your manual out and make sure the trailer is supposed to be wired as 24V instead of 12V. I've had RVs since the 70's and have never seen a 24V setup. It is possible that whoever connected the batteries put them in series instead of parallel (assuming they are 12v batteries).

Yes definately something wrong no airstream was ever made to run on 24VDC.
Are you running on batteries now or on shore power. The PO may have messed with the power converter.

thank for the feedback..I rechecked the voltage based responses. ID10T error and 1 too many new castles. I had the polarity reversed on my voltage meter and it was reading the
-VDC LED.

Thanks

I've made lots of ID 10 T errors myself and I don't need newcastles to do them. Glad to know somebody else speaks techie.

You know, a true ID10T would never have posed the question.

Glad you're with us.
