Hi all,
My 77 Johnson Stinger 75 was working fine all weekend, usually starts with the flick of the key cold or warm. We had been using it, and it sat for maybe 5 minutes off and then the starter would only spin but not engage the flywheel. I pull started it, drove to shore, swapped batteries and it started and ran fine once, then reverted back to not engaging. That day I did hold the starter gear up into the flywheel while my wife turned it over and it would crank and crank but not fire. I did not have a spark tester along to check.
Both batteries are charged up, battery connections have been cleaned, Bendix oiled lightly with gun oil, battery cables are new and free of corrosion, I am getting 12.25 volts at the battery and solenoid, and while cranking the starter side of solenoid is 11.94 volts-12.05 volts with the two different batteries.
The Bendix seems to move up and down freely by hand, and both the starter, solenoid, and battery cables are 2 years old with maybe 40-50 hours of use on them. I also noticed today that the electric choke does not work when I push the key in also.
The rectifier did go bad last year, and instead of buying a new one I used the one off of my dad's 1972 Evinrude 50 hp which is still on the Johnson now.
Does anyone have any insight of what else to check before buying new parts? Thanks in advance.
