I've read in another P6 forum that some 3500 owners are replacing the 11AC alternator with a Lucas A 127, which is more readily available. In addition to ease of access, this alternator is purported to produce greater voltage (14 plus volts) and smoother performance. My recently rebuilt 11AC produces 13.3 volts at best. As the Lucas A 127 has an internal generator, when installing, I assume one would bypass the wiring to the external generator/regulator and simply have positive and negative leads on the alternator, but, I am out of my league here. The A 127 (LH) is said to fit into the mounting brackets without need for adjustment or alteration. One comment was to the effect that a higher gauge positive lead would be needed. Does anyone here have any further information or experience regarding this swap out?
