Caravan 12v fridge power solution followup

Hi Bonz. No problem with polarity as I had traced the wires from the plug at the front. It had me buggered why I had power to the Setec with the vehicle ignition on. Turns out that was the onboard battery charge wire from the Prado and the fridge wires had been wrapped in with it. With all the other wiring down in the cavity it was impossible to see. Cheers, Bob

Well done to track it down, sometimes the simplest things are overlooked cause they are too far off the beam

Interesting observation Re: the wire colours. I also have a jayco and noticed the same thing. I am lucky to have a brother whom studied electrical engineering and circuitry for many a year and so was able to ask him over the phone LAUNCESTON-WANGARATTA, and he soon set me straight. Why, oh why do they do this, as I am sure many a handyman has been fooled by the same. Why not leave the wires RED and BLACK so no confusion can Reign over the masses. Incidently, whilst on the jayco circuit and fuse boxes. Some of them can not be repaired if the diodes and resistors blow, as the components are not available as spare parts. A whole new fuse box and connectors has to be purchased. In Jayco poptop trailer vans the fuse box is located under the seat, and if you remove the plastic grill, you will see all the fuses lined up, so if any circuit is not working, check these fuses one by one and you will possibly find a blown fuse is your problem. If this doesn't work, check inside your cupboards and you will find inside one of them a fuse trip switch, similar to your house fuse, which may have tripped. Switch it off and then back on, then all should be fine and dandy. Cheers, Cashman,

Have to agree with you there Guy. As you can see the fridge wires are red + and Black - and then the harness wires that join to them are pink + and white - The Setec has one Black wire which is + The rest are white and some are + and some are - Sure makes it hard to trace circuits. Cheers,Bob
