1990 ADRIA OPTIMA ELECTRICS

[DARRAN_5114918]

I HAVE JUST PURCHASED A 1990 ADRIA OPTIMA.WHEN NEW IT HAD NO ON BOARD BATTERY AND HAD A SINGLE SOCKET TO CONNECT TO THE CAR FOR TOWING LIGHTS AND CARAVAN POWER,THE PIN ON THE SEVEN PIN SOCKET WHICH IS NOW USED FOR FOG LIGHTS WAS ORIGINALLY USED FOR A 12V FEED FROM THE CAR TO POWER THE INTERNAL 12V SYSTEM INCLUDING THE FRIDGE THE ONLY OTHER SOURCE OF 12V POWER WAS WHEN CONNECTED TO 240V HOOK UP A TRANSFORMER/RECTIFIER IS POWERED UP AND SWITHCHES A RELAY WHICH DISCONNECTS THE 12V FEED FROM THE CAR AND USES THE TRANSFORMER/RECTIFIER 12V TO POWER THE 12V SYSTEMS..HOWEVER IT HAS BEEN ALTERED SO THAT THE 12V FEED WHICH ORIGINALLY CAME FROM THE CAR BATTERY HAS BEEN DISCONNECTED FROM THE 7 PIN SOCKET AND CONNECTED TO AN ON BOARD BATTERY WITH A 20A IN LINE FUSE ON THE POSOTIVE TERMINAL. DOES THIS SOUND LIKE AN OK UPGRADE?. ALSO THE CARAVAN BATTERY NEGATIVE IS GROUNDED TO THE CHASSIS AND THE EARTH FROM THE 240V AC SYSTEM IS EARTHED TO THE CHASSIS IS IT OK TO HAVE BOTH SYSTEMS GROUNDED TO THE CHASSIS.ANY ADVICE WOULD BE WELCOME.

The Blue wire in 1990 should have been for the fog lights from the off and Adria's had the second 12s socket long before this time anyway.

The big problem you have is these vans were imported and then converted over here by sub-contractors! This makes it impossible to know what was done to your particular van.

From Adria's I have seen of the time, I am surprised you have not mentioned how bad some of the wiring is..Spaggetti springs to mind!!

Sorry not much help I'm afraid but can you switch your 'caps lock' off next time, its a devils job to read and considered shouting on the net!!

Thanks for your input garry ,sorry about the caps lock.looks like my van was purchased and used abroad before coming to this country as i have all the original paperwork and booklets including the sales recipt when new but they are all in french.i have the original wiring digram which does show only one 7 pin socket and the caravan 12v feed was originaly taken from pin 2.
