Perkins 4-108M Switch details

[pbanderson]

I am trying to replace my engine switch and Perkins is less than helpful and don't make a replacement. The wires are a mess and I don't know where they terminate. Does anyone have a wiring/terminal diagram for the 4-108m ignition switch.

no, I don't know, but I have the same question. My ignition switch on the same motor on my sailboat has quit working and i need to install a new ignition switch, that comes with no schematic or instructions.

Ahh! I see I'm not the only one frustrated by Perkins wiring!

I've found that the engine owner's and workshop manuals are not quite exact in this area, since it's obvious that my instrument panel is generally different than those shown in the diagrams.

Which switch do you have? Is it the four position (Off, Run, Preheat, Start) switch, or a two position (Off, Run) with separate starter and kill buttons?
