30amp service not charging battery

Hello everyone. Thanks so much for all your help so far. We have worked out a few of our trailer issues - hot water heater replaced, all leaks repaired and we are out on our first adventure. We have a 1990 T-2363. An ongoing issue we are having is that our 12volt system is not charging from the 30 amp. We did check the fuse at the front of the trailer, but still draining. We end up hooking up our battery charger to keep it powered - fine while we have campsite power and room to haul it - but we will be in places where we won't have this option. Do any of you have any ideas on what the source of our trouble is?

I would check where the battery wire goes into the converter. Make sure the connection is tight. There could also be a circuit breaker somewhere in the line, that is no longer functioning.

If you have a volt meter, set it to 12v and check the wire from the converter, where it goes out to the battery. With the 30AMP unplugged, you should see battery voltage there. If not, there is a loose/corroded connection somewhere between there and the battery.

Hi Shelley,

Tell us more about the draining. Does this happen when the camper is in storage or when you are plugged in at the campsite?

On your older model unless some one added it, there is no dissconnect switch up by the battery. When you return from camping and store the camper, you need to unhook the negative cable from the battery to stop the draining from things in the camper that are still using power. The LP gas detector is always on. Some times folks leave the tv attenna power booster on and then there is the radio if your has one. Unless you pull the fuses inside from the battery charge line, the camper will drain the battery.

Now if this is when you are plugged into shore power and it still drains, then your on board convertor may not be working or the power is not getting to the battery.

Like EMD_Driver stated, if you have a 12 volt meter, a battery that is charging should be above 13.2 volts, more like in the 13.65 range. If it is only reading 12.5 or 12.0 then the battery is not being charged and you need to start backtrccking as to how the power is not getting to the battery.

Hope this helps

John
