Its an outboard engine with remote control labeled OMC. I tried to replace the original ignition switch (pollak pat.5237133) with a Sierra mp39760. I thought it would be an easy thing to do but when i tried to start it afterwards i shorted the battery. I have been looking high and low for a wiring diagram but cant find any.
The connection points on the old key switch are labeled:
- A
- B
- C
- M
- M
- S
The connection points on the new ignition switch are labeled:
- I
- B
- C
- M
- M
- S
The colors of the wires in the remote control are:
- Red
- Purple
- Purple with white stripe
- Yellow with red stripe
- Black with white stripe
- Black with yellow stripe
The only thing i did different in the wiring is connect the one labeled "a" on the old switch, to "i" on the new one.
