Need to replace a 8EM2008NA

Need to replace a 8EM2008NA on a 1989 Cummins 6BT in a marine application. The 8MR2301LS has a Packard Connector and a number of wires on the rear. The 8EM2008NA only has two wires going into it. One is the positive output and the other presumably is the exciter lead(stator terminal?). The 8MR2301LS has a Packard Connector and a number of wires on the rear.

Where do I connect the two existing wires on the boat on the rear of the 8MR2301LS?

Thanks

Alt. Amperage too high

I recently replaced a 55 amp alt with a 90 amp Leece Neville. I have replaced batteries and checked all wiring connections and replace some older wiring with like gauge. Problem is the amperage output on the meter (-60 +60) is pegged to the b+ side. Any ideas as to what to look for or where?
I appreciate any help or assistance with this.

Alternators

Have a older prestolite alternator 1993 ? Connections on it are : Bat. excitation and I believe S . The boat and motor manual show bat , solenoid and ground wires . Alternator is being repaired right now . What would be the correct wiring diagram ?
thx
