Neptune coil wanted.Model 10A4 CT

Postby gizmoh » Thu Sep 13, 2018 9:35 pm

I bought this little Neptune opposed twin and I believe it needs a coil.Tested the condenser and cleaned the points without success.Next I installed on of those "atomic" red modules with the same success.Tried power testing the coil but it would not fire the Merc-tronic.Mag.Model 72F.Any help or advise would be appreciated.I can be contacted at (860) 941-7755 or ken1401732@aol.com.

Eisemann Model 72 Magneto was used on several brands of outboards both prewar and postwar.
Kiekhaefer (Mercury) used Model 72H. Some parts may vary but coils may interchange.
Sometimes old rusty stuck have surprises inside.

The Eisemann Model 72 F for an opposed twin likely has a different cam and flywheel than
an Eisemann Model 72 H which is for alternate twin Mercury and Wizards but the Coils would
likely be same.
I asked and electrical engineer about rust on laminates and was told it would not be a problem
How is magnet strength? Some prewar magnetos could benefit from a recharge.
The magneto in photo was on STUCK and then some WD4S. I believe several brands used
variations of Eisemann 72 magneto. I think there may be a cross list of part numbers
of Eisemann 72 magnetos similar to onees I have seen for Bendix and Repco Phelon
which would verify parts changed and parts in common various versions.
