" i rebuilt a 1975 75hp johnso
" i rebuilt a 1975 75hp johnson...i was told the powerpack was kaputt...i replaced the power pack with a new one...i only have the engine..the boat is elsewhere...i crank it (via a battery jumpered to the starter) but i get no spark...the sensors are putting out 3 VAC(cranking)..the charge coils put out 170VAC (i do not have a peak voltmeter, just a good digital)...i have looked at the diagram from my climers repair book an see that the sensor coils are tied into the powerpack different in 1974/5 than they were in 1976/7...i see they are attached in the 1976/7 way...
my questions are: 1) shouldn't the motor still produce a spark output even if the electrical connections to the boat are not attached...according to the wiring diagram it appears the key just grounds out the powerpack to shut off the motor...
did OMC make different powerpacks for the 74/5 and the 76/7 model years?...the guy i bought mine from just gave me what i thought was the correct one... "
