We have 65% humidity, its not pleasant in the shade lol...There was virtually no breeze until I finished 2 hours later...It's replaced and drove the mower back home...
Did you check the coil?...Could be losing the 4 volts there...
...
that sounds quite uncomfortable out there,
the drive belts sure don't look easy to get to on them
and your 2 hours to change it just verified that for me
mine has magnetos, they are not connected to the battery system at all.
I can check for voltage drop with a volt meter, so I can tell the issue is somewhere between the battery and the starter
the issue is that it is not consistent,
and can't seem to catch the problem happening in any particular section with the meter connected.
but now I have huge battery cables that are new, and a new solenoid, so that is not the issue,
it did just occur to me that it is likely the only thing I did not replace, the cable from the solenoid to the starter. it looks good, but I guess it is next to get replaced
I got it for free because it had electrical issues.
not even sure how they ran it long enough to have so many thing broken on it, but maybe the electrical broke all at once
I am about 3 wires short of having replaced the electric entirely.
and seems to me that they were not meant to be parked out in the rain
