Thanks in advance for your help! I have a 1996 Volvo Penta 5.7L carbureted gas motor (GL PLKD). I was having issues with my ignition modules going bad so started checking for bad ground and/or alternator overcharging. Grounds were all good but the alternator was charging 15.5V at the battery at 1300 rpm so I replaced it. However, the new alternator is charging at the exact same rate. So now I am wondering what could cause this? On my diagram, I have hooked up 4 wires (orange power to B, black ground to E, tach purple white to P, and ignition purple to EXC. There is also a jumper wire that links EXC to S (shown in red in my diagram). Is this jumper wire correct? What does it do? Might there be some other cause for the overcharging? Thanks!
