Fridge not connecting to car battery
Hi looking for some help. I have a 2015 sprite 6td. I used my local Vauxhall dealer to fit a tow bar and 13 pin socket to my insignia. All external lights work okay but I think my fridge is not connected while plugged into the car and not sure but think the leisure battery may not be charging when connected to the car also.
I have read a few similar posts on here and I have checked the panel above the door to see if it flashes while my oh revs the car......nothing. When I put the fridge fridge onto the battery, the battery symbol on the fridge panel just continuously flashes which if I'm right there is no connection to the car battery found.
i would appreciate and help on this as I would like the fridge and charging battery working before my long journey in a few weeks to Great Yarmouth.
