All the locks on my van are broken so I rely on the central locking via the drivers door. Its a bit of a pain and I have new barrels to fit when I find the time.
Today I went back to the van to get my phone and none of the doors unlocked. this is a problem because there is a bulkhead between the cab and the hab area. The back door does not have any means of unlocking it mechanically at all.
The drivers battery was flat…..
There was a brief oh shit!!! moment then engaged the brain. I had fitted a Battery to Battery charger behind the drivers seat a few months ago so thought I know. I will try cross linking the two + terminals and letting the leisure batteries put a bit of charge into the Engine battery. I put a bit of 6mm wire between the two terminals and kept hold of it for 5 minutes to see if it got warm and by how much. It did get a little warm so I wasn’t going to leave it there. I then got my spanner out and disconnected the engine side and attached this to the leisure side. Now this cable is 25mm and it worked fine. I started the engine using the leisure batteries and left it to run for an hour.
This was not an ideal situation but I don’t have 240V here and don’t have a 12v battery charger spare. My last one burnt out…..
I am now glad I got this fitted. I am going to put in a 100amp switch that will disconnect the engine battery from the charger and connect it to the leisure batteries for future emergencies. I will use one that has a key so I can’t leave it connected while driving. I need to think on this a little while.
I had better get the locks fixed as well while I am at it….
