It's a pull-start with a simple rectifier (4 diodes). All the diodes have been checked...forward and reverse bias. The alternator winding checks out OK, with no shorts to ground. When the engine is started, the battery voltage increases by maybe .01 volts even if the engine is "raced". I used Ancor marine cable between the engine and the battery. I used Ancor adhesive-lined heat-shrink terminals. Is this likely a high-resistance somewhere in the wiring? It's in a sailboat with perhaps 20' of cable between the rectifier and the battery. Oh yeah, I am an Electrical Engineer!
