Hey all, thanks so much for your help so far, we're still trying to learn all the ins and outs of owning a bus.
We tipped the battery on it's side and had no leaks, I used a bit of rubber sealant around the terminal just in case. However, today we went to start our bus, and it won't turn over. The engine only gives a rev or two before going dead. When I turn the key all of the dash lights flicker which makes me think its an electrical problem. However, upon testing the battery it read 11.6 V, and we tried jumping it with a friends car to no avail.
We're considering going to buy another battery just to try it out, unless anyone here has some advice for some rookie skooliers.
