Force 90ph alternator..."P" Type??

[malcolm.fraser]

Hi all,

I have a Force 90hp Model 908E92C.

It apparently has the Thunderbolt CDI ignition and I am now putting a new 2 battery (Start-House) system in. Looking at installing a smart regulator for the battery charging but can't seem to find out if the alternator on these models is a "P" Type (where a positive voltage is applied to the alternator field coils).

Anybody got any ideas or experience on this??

The engines are all negative ground. The alternator stator has no impressed voltage applied. Rotating magnets inside the perimeter of the flywheel induce a voltage in the stationary stator. Dirt simple. The stator will deliver about 16 volts AC and a regulator/ rectifier will reduce it to about 14 VDC
