New battery, no power?

[bloomis2925]

Spring has sprung and I put a new battery on our TT. Hooked the battery up and I have no power in the camper when on battery power. Shore power, everything works fine. Only thing that works on battery is the power tongue jack, but it is direct connect to the battery.

I checked all the fuses in the converter/ fuse panel, they are all good. Is there more fuses located anywhere else? I've crawled all over the camper looking for anything that may be the issue. I've also searched the forums, but put in "battery" and you get a lot of results.

Not sure if I am missing something simple or not.

Thanks for your help in advance!

Maybe it hasn't had enough time to recharge off the converter? You could try turning off the converter and using jumper cables off your TV to see if there are no bad connections in the A-frame area. Electrolyte level okay? You can use a voltmeter to see what the state of charge is and what voltage the converter/charger is putting out. With 120 volts to the converter turned off (at converter panel), use a voltmeter to see what voltage is showing up at the converter from the battery (take front panel off converter) - do this with no-low DC load and then turn on a bunch of DC loads.

Last year we had our battery develop a bad cell in under a year. Would not hold a charge. A battery shop diagnosed it. You could take the battery to a battery shop for testing.

If you are sure battery cables are correct (not reversed....tongue jack doesn't work backwards) then follow Battery POS cable from battery to the In-Line Fuse (or DC circuit breaker) on frame. Check for DC voltage on both sides.
Fuse/CB could be bad (some CBs have small tab on side to reset them)


IF cables hooked up backwards then 'Reverse Polarity' fuses on converter have blown Large 30A or 40A fuses
Correct battery cables (NEG to frame) then replace those fuses.

No problem with the simple suggestion! The camper does not have a main battery shut off. I installed one myself originally to keep the battery from draining in storage. I actually removed the switch to make sure that wasn't the cause of the problem trying to figure this out, but it wasn't.

You know I had this happen to me tore into many things checking, but only worked on shore. Frustrated I went onto something else, when I opened the front storage there it was, I forgot to turn on the main power. Turned it one and wala everything fine.

Have you checked the main battery shut off? Sorry to be so simple but it caught me.

OH, forgot to put camper info. 2015 North Trail 28BHS. Battery died because my trickle charger died on me over the winter and screwed the battery up. My fault for not checking on it, but it was a crazy year of kid's hockey.
