I have a Coleman pop up. I put a converter in it, It is a progressive dynamics. I am trying to put a car stereo in it now. I have 12.6 volts at lights and water pump and the feed wires for the stereo. When I hook up power to the radio everything is fine but when I hook up the memory wire to make the radio turn on my lights get bright and the voltage through out the system goes to 16.5. The stereo plays for a little bit then starts skipping and gets real hot. I ruined one stereo by not checking into this and don't want to lose another one. I have tried 3 different stereos and they all do it. What am I missing? I do not have a battery on the trailer is this the problem?
Please help goin on a 4 day camping trip soon and want everything to work properly. Thanks

The memory wire is just to draw enough power to keep the memory live. A milli amp or so. It should operate without this wire attached and if you have no battery, you don't need it.

You really need a battery to stabilize the system. Spiking the voltage is what is burning out the stereos. A battery will calm it down.

Quite likely this IS the problem. Pull a 12 VDC battery out of your car/truck and temporarily install and see what voltage readings are.

Ther aren't any wires to hook a battery up to. This camper never had a converter in it. I am putting it in to run a water pump and the lights and stereo. When I got camper it had a 120 circuit breaker panel in it and that was it to run 2 lights. The people used it as a tent up off the ground. No gadgets at all.

Though there are a few chargers/converters that will work without a battery, having the converter feed a 12 VDC battery (even a relatively small one) is a good idea. Then wire battery to fuse and fuse to accessory.
The battery size really depends on how much you want to be able to run while not plugged into 120 VAC.

You hook the battery to the 12V wires you are now using to run your 12V appliances, stereo, lights, etc. That's how a converter charges the battery. Then hook all your 12V. stuff to the battery. As said above, borrow a battery or use one from your auto/truck and try it. I think you will see quite a difference.

If this is the wiring for the battery why does my converter have a switch to switch from converter to battery. If you just wire the wires to the battery. I am more confused now then I was when I posted this. If the switch is on for converter I didn't think I needed a battery. Every thing else works at 12.5 volts without a battery hooked up. What does the switch on the converter do? I was told by rv dealer that this model converter does not charge batteries. You flip the switch to battery to run the lights and such when you don't have electric power avail.

the red wire from your stereo is switched power, and the yellow wire is constant power for the memory. If you don't have a battery, don't hook up the yellow wire, because you can't have a memory without a battery.

If I don't hook up the yellow wire the radio doesn't even turn on let alone work. If I hook both the yellow and red wires together then hook them to my jeep battery they still only show 12.6 volt. Why does the voltage go up in my camper. Only 12.6 volt comming in till I hook up the yellow memory wire. WHY?
