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

You might hook up a battery temporarily to see if it works better.
Maybe the polarity of the power wires is reversed at the radio.

I don't think the polarity would be reversed on three different radios. I am using the wire diagram that came with the radios. When radio hooked up in car the voltage change doesn't happen.

Try the battery then.

Have you checked your PD manual regarding whether a battery must be connected?
I've never attempted to reverse polarity on "car stereos," but every one I've seen recently has proprietary polarized connectors(including the "memory" wire) to prevent just that.
My PD-9160 and 9180 both operate all 12V appliances/lamps just fine---including my sound system, without my battery bank connected.
FWIW: Just checked my sound systems---three in three different vehicles....they all have polarized connectors (which include the memory wire), and solid black is connected to ground on all three.....two have red positive wires and one has black with a white stripe
And did you blow the inline fuse on your stereos? It sure sounds like you reversed polarity on the" memory " connection....It also sounds like your PD may be "sensing" the resulting short as a battery needing charging---but 14.4V is normally the max voltage output on mine.

You need a battery in the circuit. You converter is a battery charger, not a power supply. It sees the battery voltage and adjust the out put voltage to charge at different rates. Just go get a Walmart Everstart and put it the circuit. Bill

My converter doesn't have a battery charging circuit on it. Thats why I didn't put a battery onboard. Why doesn't the voltage change with the water pump hooked up and turned on. Why do my lights get brighter? Why only when I hook radio up? Why doesn't it blow any fuses when I hook the radio up and the lights get 16 volts thrown at them. I am using all pioneer radios and they all have red hot wires, black ground wires, and yellow memory wires. And all make the system act up when I hook up the ememory wire. just using the power wire everything is fine except radio won't turn on without memory wire hooked up and thats when the problem starts.

What is your model of PD converter? I know that the 9200 series doesn't need a battery to provide 12v to the system. Try it with a battery across the main 12V output of the converter and see if there is any difference.

The model number is about 10 numbers long .I bought it out of a wrecked 95 dutchman camper.

Did you say you installed the converter yourself? What model number is it? Is there a place to download the wiring schematics?
I've never heard of a converter which doesn't provide a 12VDC output to the battery. Could you be confusing a standard battery charging circuit with a "smart charger" circuit?
Regarding fuses not blowing... A circuit should be fused for the current carrying capacity of the wire. A 35 watt bulb supplied by 12.6 VDC draws 2.7 Amps of current. That same bulb supplied by 16.0 VDC draws only 2.2 Amps of current.
I wonder what the waveform of that 12 VDC output looks like with no load on it? If that memory wire is looking for a nice FLAT 12 volts (like a car battery) and the converter is pumping out something that ripples between 14 and 10 volts, maybe the radio is going into a funny state. You said that the memory wire has to be hooked up before it turns on... could it be power cycling very fast and confusing the converter?
