Extra 20amp feed required for caravan

[flyerdave]

Hi

With my old 406 I took a separate lead straight from the battery and created a new caravan supply as the 20amp standard one was not enough to really cool down the fridge when travelling.

With this new (to me) 406 1997 1.9lxdt I am thinking of taking a supply line off the rear window heater (30amp) as an extra supply. Of course this would only draw current when the engine is running via a relay and would only cut in when a separate switch would knock out the heater.

I have some questions.

1. would this cause any problems with the electrics?

2. If answer to 1. is yes is there anywhere else on the backend of the car that i can get a 20amp supply from?

3. if answer is no, does anyone know whereabouts the connector to the heated screen is located so i can link into it?


thanks.

I dont know where the heated screen wire is but the bootlight wire if you take the +ve off it and then get the negative from the cars body ie ground it you should have a permanent 12v supply but i just am not sure if its enough amps

Does anyone know where the connection to the rear heated windscreen is?

I just don't want to have to rip the backend apart.

thanks

The wires for the rear window heater are in behind the cover for the c pillar

Thanks for the info.

Hi,
As this supply will only be available when the heated screen is on, and you will need to fit extra relays and switches, I think your original feed from the battery is the best option.
