1992 Eurovan camper, Rewiring to new aux battery charger.


New member
Hi, I have a 1992 eurovan camper on which the auxiliary battery charger was changed by the previous owner.

When he did this, he did not reconnect the wires that where in the six pin connector that connected to the original charger.
He just connected the new charger to the aux battery.

So one thing I see is missing because of this, is the little symbol of a two prongs electric plug is not showing up on the central console display above the mirror. It is not showing up when I plug the camper to a power outlet. Voltage on the display does go up to around 14V when connected, so It looks like it is charging the battery.

The six pins connector and all it's wires is still present next to the new charger.
Can someone tell me what is the proper wiring for everything to work with new charger?

Thanks for any help.

Did you solve the problem with the power indicator?
No, I did not solve the problem.
But everything works, except for the electric plug symbol not showing up on the display.
After doing some more research, I think you need to have the original charger to get this to work. The electronics in the charger was probably sending a signal to the console confirming that AC power was connected. Anyways, everything else is working, so it's just a display issue.

Thx for your answer.
I made some research and found this charger, https://www.fraron.de/faq/batterieladegeraete/

The wire named LED should be set to +. Original I think this wire had 2volt as output at 10mA to drive a standard LED. When there is no load (no LED connected), the voltage is probably 12V.

Just tested my old power supply, no physical damaged but no outputvoltage...
Will probably buy a new ctech charger tomorrow.

Did you get a price for that Fraron charger? I think I had seen this unit when I was trying to solve the problem last year, but it was expensive.
Also, this is a 230V unit for use Europe, I'm in Canada and we use 120V.
I also have the original charger. It had a couple of burned fuses that I replaced, but still no output voltage.
Probably some fried components on the PC board.

Hi again,
I found the price for the Fraron charger.
199.00 Euros, or around $225.00 US
And like I said, it's a 230V unit. So not good in North America.
