I pressed the starter switch and heard only the solenoid click but no cranking. After only a few seconds the battery cable was very warm. I disconnected the + cable from the starter and attempted to jump the starter with a good battery with the negative connected to the block and the positive to the starter but got only sparks. (I switched over to 12VDC with negative ground about a decade ago and continued to use the original starter.) Does this sound like a starter failure? What should I expect during a removal and replacement? Any advice will be helpful - especially a Utube description. Thanks.
