I just bought a 81 Ranger in neglected condition. When I tried to turn the engine over, I hooked the battery up and something popped and a wisp of smoke came from beside a blue thing on the starboard side of the engine. Come to find out my battery has reversed polarity. I have to hook it up backwards. Never heard of that before but I tested it with several meters. Anyway, the starter will spin, the bendix engages the flywheel but I am not getting any spark. Any suggestions?<br /><br />Thanks. Sorry this is so long.
