[QUOTE="kofkorn, post: 419565, member: 7076"] Based on your model number, that should be a 1977 70hp Johnson motor. Johnson didn't make a 70hp in 1970. That part is your power pack. It takes the charge from the alternator and takes the timing from the timer base and sends a electrical charge to the coil at the correct time for ignition of each cylinder. Basic rundown of positions 1) Output to cylinder 1 coil 2) Output to cylinder 2 coil 3) Output to cylinder 3 coil 4) Connection to Stator 5) Connection to Stator 6) Kill wire from ignition (grounding this wire stops output to coils) 7) 8 ) Input from Timer base Position #1 (triggers Output to coil #1) 9) Input from Timer base Position #2 (triggers Output to coil #2) 10) Input from Timer base Position #3 (triggers Output to coil #3) 11) Connection from Timer base 12) Ground Good luck!
