I own a Winnebago 2006, just purchase 2- 12 volts new batteries and connected the same way it was before (series). Try my onan 4000 generator and gave me an error 27(battery connection not 12 volts but 24). I had power inside the MH.
Changed connection to parallel, no power inside the MH. No power on my generator. I am confused if the connection should be parallel or in series. Can anyone help

They should be in parallel.

Something probably got blowed up when you connected 24 volts.

I’d check the fuseable links, breakers, fuses.

Insurance may cover it.

Connection of two 12 volt batteries in series sent 24 volts through your system. IMO you should start by checking all your fuses and breakers. Pray first.

Parallel gives you 12 volts. ++ and --

Series will give you 24 volts. May have opened a fuse or some other damage. Some items are more tolerant than others.

Did the forum drop you here when you signed up? You probably wanted "Tech Issues" or "Class A" forums.

I got a call to help a friend with electrical trouble on his RV.

He had replaced his batteries and accidentally hooked them up in series. 24v....

We had propane to replace the converter, refrigerator control board and some light bulbs.

Some things are simple for some and . ... Way too complex for others.

Batteries.. On of 'em Now I can look at an automotive type lead acid battery and tell you at a glance if it's a six or 12 volt and how to hook it up. Worked with both sixes and 12's since my teens (now lat 60s)

But ... One story here was how an RVer went to a dealer and had them put in new batteries.. WRONG.. Yup. A professional messed it up.. What more can I say.

LIkely a breaker tripped (Battery main) or the "oh-shi!!+_ fuse blue (Battery main) or the re-connect was done wrong.


Home is where I park it.
