Has anyone found that there are problems with the Bosch alternator on the 560 series engines. I recently bought a 1986 560 SEC and soon found that it was only charging at 12.7 volts with no load. Problem was a burned out diode. My 1987 560 SL appears to have the same problem, and I'm taking it off to have it repaired. Anyone with similar experiences?
1986 560SEC: 150,000 miles, runs great, but I've got to sell it (too many cars for one man)
1987 560SL: 122,000 miles, used to run poorly, now (thanks to forum), runs great!
1997 GMC Jimmy: Turned out to be a turkey.
1989 T-Bird Super Coupe: 150,000 miles, still runs great. Ford got it right.
