Her in doors bought some furniture and it is ready for collection today. I went in the garage too get the camper out which has been in hibernation since early september ...Except for 1 trip to wicks to get plaster board. I opened the door and holly stink there was a horrible pong!.... First though was that maybe i'd not emptied the waste water... But a quick sniff at the sink and that was fine. Then a quick sniff of the chemical toilet encase i'd forgot to empty it...Fine.. a quick route about but the smell was every where and really acrid. So strong I coun't really say what the smell was. Anyway it only just started. Which i thought was odd as its been on the Ctec since being parked up. Driving to work freezing to death with windows open everytime i closed my window the smell was back, and seamed to engulf me immediately.. It reminded me of my work experience placement at Pembroke petrochemical labs. A real sulfurous smell, i wan't sure if there was a whiff of burning wires in the mix. I had to stop the van and have a fresh Sniff. The smell was everywhere but i thought it was worse at the back of my seat. Envisaging finding something rotting I moved the seat forward and nothing was to be seen. But the battery was roasting hot. I disconnected it lifted it out to see it was also leaking... The condition window looked empty. This battery was the original "petrol" starter battery. When i fitted a TDI engine I also fitted a large battery in the engine bay (at the rear vw T25). So really only the rear battery was needed. But still more batteries the better in my eyes in a camper. So if you go in your garage and there is a horrendous smell don't blame it on the dog, it might be your battery!
