So I re-wired the old starter switch to make a push button start with toggle switch for the 1 mag and 1 electronic ignition. The new system works fine as far as starter and magneto/EI functionality goes but now for whatever reason the Tach no longer reads RPM on the E.I. Engine monitor. I've attached a diagram of what I have going on. I believe the two white wires (green in my graphic) are the tach wires. I think there are two because this motor is a H2AD and has the dual combined mag setup and I believe he just combined the two onto one terminal when he put in the EI but I'm not sure.
In any case, I was under the impression from an electrical standpoint that my new wiring setup is exactly the same as the functionality of the original switch. But I'm obviously missing something.
Any help is much appreciated!
