Hi,
Looking for a bit of electrical help\guidance.
I have a D14/4 fitted with a direct ignition D7 engine.
I am not sure if there is any way of using the D7 generator with the existing twin switch D14 wiring loom
i did think about trying to source a D14 engine until I saw the price!

The switches are the same, but not the wiring harness
so you could make or buy a D7 wiring harness use the H/Light sw for lights
and perhaps use the ignition sw as a engine on/off switch

Hi again
Thanks for all the information.
From an internet search it would appear that a D7 twin switch loom is readily available.
I assume that a 1704 geny is a rarer item. Is there a source you could recommend who could supply.
Thanks again

i was out looking for geny parts over the W/end , A MAGNET ROTOR is MUCH rerer than stators your rotor MUST NOT tuch the staytor legs so chec the gap between the two the rotor must have A/C D/C on it , , im hoping to WIND up some new coil soon so i can upgrade the D 3 s 1450 spec to a 1704 if needs be ,,

This is the current arrangement that is fitted
I assume that this is the standard set up for a D7
i am struggling to identify 1 stator from another

The stator type is engraved (lightly) to the left of the SERIAL NO, lower right of the casting. Yours looks to be 178#. You are also missing the lubricating felt for the cam.
