went to my dads again today, his 2n won't turn over again, thinking it was one of three things, starter, cutout relay or push
button not grounding to complete loop. all check out in working order, his freshly charged battery showed 6.25 as soon as i push starter button is drops immediately to 4 volts and obviously won't turn over, i brought a backup 6v battery freshly charged and tractor fired right up.
questions...
he uses a battery tender to maintain battery charge, could he have over charged his batteries?
he's 82, if reversed the clamps could that have ruined the battery and caused the battery to be charged but not hold a charge
later?
the one wire genny at 1/2 throttle shows on analog meter 6.5 volts, could that eventually drain battery, is that enough? i know it
should show 7.4, even after playing with hi/lo adjustment on genny
at this point i can't get his tractor to fail
any input would be great
 
" his freshly charged battery showed 6.25 "

You need to have it load tested; 6.22v is 75% charged.

" he uses a battery tender to maintain battery charge, could he have over charged his batteries?"

If it really is a float charger in working order and not a trickle charger, no.

" if reversed the clamps could that have ruined the battery and caused the battery to be charged but not hold a charge
later?"

Do you mean he changed the polarity, ie, hooked it up negative ground?


" i know it should show 7.4"

That's right. And if it isn't, you are not charging the battery.

Did you try jumpering the two wires on the cutout with your
battery in it to see what it reads across the battery terminals then?
 
yes, if you hook up battery tender red to neg and black to pos. what would the results be?
not sure he did this but can't believe the battery went that dead that quick,
also, on this cutout relay, if it is not working correctly and the points are permanently closed maybe causing drain on battery could i check it for continuity by testing each terminal on the cutout?
thanks bruce
 
you mean check current from cutout input terminal by jumping input terminal directly to battery? and then test output terminal to battery?

thanks lawson
 
You're looking for 7.4V across the battery terminals.
If you hook your meter up to measure that, you said you got
about 6.5V. Now that you've got it hooked up and showing 6.5V
with the tractor running, connect the two cutout terminals together
by touch a piece of wire between them. Does the voltage reading
go up to around 7.4V when you do that? It should.

Don't leave that jumper wire on there.
The cutout is basically a switch. It connects the two terminals
when running and disconnects them when not running so the
battery doesn't get drained while setting.
