Ok, so I didn't pay attention during class when they talked about electricity and this is the first time i've had this problem, so I need some help... in layman terms please! I fly a C208 (Caravan) and tonight during preflight, I noticed that the battery was dead. I think one of my loaders turned on the courtesy lights in the cargo area without me knowing this morning. Anyway, it is a 24volt, 43 amp/hour lead-acid battery. The airport manager where I fly out of offered to help. I was expecting him to roll an APU next to my plane. Instead, he brought a golf cart with two 12 volt car batteries lined up in series. I had serious doubts this would work because for an auxilary power start I need a minimum of 800 amps, with a max of 1700 amps. I was indicating 25 volts, but not sure how many amps I had available. I followed the procedure per the checklist, but the starter/generator didn't even start to turn. My question is: Is it at all possible to start a PT6A-114 that needs a minimum of 800 amps with two 12 volt car batteries in series? Is there any way to perform an Aux. Power Start without using an APU? Secondly, I am going to have the battery hooked up to a battery charger tommorow morning. There is a mechanic that is going to help me, but is there anything I should know about charging a/c batteries?
Thanks guys/gals, I really appreciate it!
