I have replaced my failed pulse pack on my 1971 125 ESL with a CDI 113-8362. I removed the clipper circuit per the installation sheet. After that I had no spark.
I went thru a long trouble shooting process. I verified 12 volts at the purple wire to the pulse pack with ignition sw in run position, but when i tried to start engine voltage would go down. A'hah you say the starter is dragging down the voltage. I tried a diode isolated connection from the starter side of start relay and motor would run only with key in start position and would stop when key returned to run. If I connected a wire from positive post of battery directly to purple wire to pulse pack engine would start and run. I opened up remote control box and jumpered between battery terminal on sw and ignition, did not fix. I did some other connection cleaning and verification to the ignition circuit also. The bottom line is that i reconnected the clipper circuit and the motor runs fine and with engine running there is 12v at the purple wire to the pulse pack. My question is this is there a jumper required after removing clipper circuit or does the purple wire to pulse pack need to go to a different terminal. There was a thread started on 07-21-15 similar to this about a 1972 100hp model100ESL72 but I never saw the resolution? There was mention of a possible OMC bulletin about clipper circuit removal but I haven't found the bulletin?
