My 1990 580K P3 has charging issues. It seems slow to crank, and as of recently needs a jump start to help it out. Using a multi-meter, the battery reads 13.16 Volts when not running, and 14.08 when running. So, I think the battery is fine. I use a gauge on the alternator that shows about 50 amps going to the battery when the machine is running. My battery cables are tight and clean, the negative cable is bolted to the exhaust manifold with a “woven” cable running from there to the frame. The manifold is rusty, and the woven cable is dirty and greasy. Is it possible that the rust and grease could be the problem? I’ve included a pic of the cable. Thanks. John.
