Ok guys this motor isn't going to win! I know someone on here can help me as I've had in the past. Ok I have a 1972 Johnson 100 hp Hydro-electric shift, model number 100ESL72. It has run on several occasions after purchasing. When I first got it the shift switch was broke (worked electrically but the little tab that rotated with the throttle lever was broke off) and couldn't get it to turn over. I did some troubleshooting and found the starter solenoid and shift blocking diode were bad. Replaced those and wired a toggle switch for the shift (per a post found on here). Got it running and took it to the lake and got out running was a little rough (carbs needed cleaning). Got that worked out and we took it out on the lake again and went about five miles from the ramp and fished for several hours went to start the motor and the starter wouldn't turn the motor over. Got towed back to the ramp. Took it home and put it on the charger and battery was dead (less than a year old). Charged the batter overnight, my step dad unhooked it at 4:30a.m. to take it back to where he worked. I got up at 6 a.m and head to the lake, get it in the water and it wouldn't turnover. Took the battery back to Wal Mart and they said it was dead and replaced it. Took it home and charged it and it started fine. Went out on the lake again 5 miles away and fished for several hours and tried to start it and nothing. Battery was dead again. Charged the battery over night again same thing step dad unhooked the charger at 4:30a.m. and I would get up at 6:00a.m. and go to the lake and nothing battery dead again. So hit the books and started troubleshooting and found I had no clipper circuit as described in book and the purple wire from the choke solenoid was connected to different spot on the terminal board, corrected that and found that the rectifier was bad, causing it to drain the battery and the white wire for the safety switch was not connected. So replaced the rectifier, shift switch, and got a clipper circuit. Everything seems to be electrically connected correct (except the shift switch was a three wire vice 5 wire so the two white wires are not connected(would like to know where should they be connected), everything test fine. Now it will not turn over at all. When testing the shift switch wasn't getting power to either the green or blue wire. Tested the purple wire (Shift blocking diode) at the switch no power, disconnected the purple wires and with switch on had battery voltage, checked he shift blocking diode and it was fine. Connected the purple wires back and changed the meter to a lower setting and got a little voltage. Checked the connections at the terminal board at #9 and had the same thing, little voltage. I also tested the shift switch while switch is in the start position and got voltage to the green wire, put switch in forward and got power to blue wire. I also got power at the white wire on the switch. So I don't have an ammeter for testing my meter is an old cheap analog meter with 10 and 250 ma settings. I tested the power pack per manual and if I did it right it maxes out my meter at 250ma. Anyone got any ideas? Trying to upload some pictures of the terminal board, rectifier, clipper circuit and col pack.
