When installing an electronic ignition, you remove the resistor wire as
the new module runs at 12volts all the time. That may also be part of
your problem as most electronic modules go "off line" at 9.5 volts or
lower.

RFI interference from the trim motor can also affect the ignition module,
either thru the air or thru the boat wiring.


Thanks for the response. The electronic ignition is wired to the
accessory side of the ignition switch and then to the negative coil lead;
the coil is wired to the electronic ignition and tachometer on the
negative lead, and the positive lead is wired to the alternator (voltage
regulator) though a 2 ohm resistance wire and a shunt line (no resistance)
to the starter solenoid (I assume to supply full voltage to the coil while
the starter is engaged).

If anybody is following my exploits... it turned out the tach was shorting
once it read above a certain rpm it would cut out and miss like crazy. Once
I cut tach wire it ran like a dream...

Thanks to all who responded to my posts. I was sure we where going to have
to change out this engine but with a little work and a lot of questions it
is running very well now.

thanks again
