Well,
Headed down to the shed and the old girl last weekend, with the many aims of fitting the destination blind in the vain attempt to make the bus more presentable, give her a bit of a clean out and test out my newly acquired sander and angle grinder!
First job of all was fitting that new blind, which still needs doing as I need to find a set of 31" long rollers to fit into the destination box equipment, missing seats, missing rollers, what else will be missing when I look more closely... Well not to be put off decided that I would see if she would still turn over despite a month or two of sitting in the cold all alone, so the ageing batteries were plugged into the booster and left to charge for a couple of minutes while I fiddled on with other things such as putting a sanding sheet onto the sander! Forgot all about the kettle, could have had a nice cup of tea!
After sanding a bit more of the orange line from the paintwork, into the cab I went, switched on the mains and ignition, and was nearly blinded by the miraculously operative again warning lamps on the dashboard, a good sign of things to come I thought! Well... turned the key, which turned the engine but still not enough power to fire the engine up... but did manage to create an impressive number of sparks in the cab from the junction box beneath the handbrake lever. Wasn't as dramatic as it sounds, knocked the power off and isolated the bus, no further problem and certainly no massive fire, but another setback for the old girl, going to need to find a sparky!
SO - if anyone is experienced with electrical systems on PCV's, I really would appreciate your help in diagnosing this problem, hopefully just earthing out somewhere or a loose or corroded connection but really need an expert view!
