Hello! So we've had the bus ('75 camper) a few weeks now but haven't been able to enjoy it with COVID and everything. I tried to take it around the block last week but the battery was too flat to turn it. I jump started, drove around for 10 minutes and parked up. Next day the battery was flat again. It has a cutoff switch/key thing connected to the positive terminal and it had been turned off since it was last run, however it also has a lifestyle battery connected via a battery isolator that doesn't go through the switch. The isolator should have kept the main battery from being drained and nothing else was connected. Do I have an old dud battery, or is the isolator failing and draining the starter battery? The other question: Should I be downshifting in to first to round corners? In all the cars I've driven, first gear is really only for starting from pretty much stopped, but the bus under-reved and coughs and splutters when Im at cornering speed in 2nd. Is there something wrong with the bus or just my driving?!
