74 cub battery issue maybe?

Postby siii8873 » Mon Dec 14, 2015 4:09 pm

I replaced my battery in my cub this spring because it was no longer startingthe cub. If I jumped it it would start. I replaced it with a blem and all was fine for a short time. Went to start it a few days ago and it needed help. Ran it for about a 1/2 hr doing some grading. Shut it off to answer a phone call and it wouldn't start. Just a click of the solenoid. I placed my charger on the battery first at 10amp manual for about 15 min then dropped it to 2amp automatic and left it on overnight, Went to start it the next day and nothing not even a click of the solenoid. Changed the battery to a spare deep cycle I had and it started right up.
Not sure what's going on here, maybe just a bad battery. I looked closely when attaching the replacement battery and didn't see any arching which could have indicated a leak to ground somewhere.

If the spare battery starts it, I'd suspect the battery. Have it tested.

put a volt meter on the tractor and make sure its charging before you blame the battery

Engine off and lights off, disconnect one battery cable. Connect multi-meter, set on amps, in series with the empty battery terminal and battery cable. If you have a parasitic amp draw it will show up with this test.

If you have a parasitic amp draw, two probable locations; regulator cut out or solenoid.

Other, previous suggestions are excellent. Probably bad battery.

Eugene, my friend has a chronic dead battery situation. I am not sure, but I think he said it was showing charge while running, but if left to sit for a few days, the battery is dead. It is 12v without a regulator, so can you explain how a solenoid can cause a parasitic amp draw? Is it internal to the coil? Or something with the wiring? Thanks for the education!

Think of a solenoid as an electromagnet, a relay, containing a coil, possibly a spring, and a plunger to activate the high amperage contact(s), battery contact to starter.

Normally the solenoid just quits, but some times worn parts wear into the coil or a weak spring fails to fully remove the plunger from the contacts.

Have your friend disconnect one battery cable and fully charge the battery. Then connect the amp meter (multi-meter) as earlier described. The disconnect one appliance at a time. When the amp draw ceases, that is the fault or area of the fault.

12 volt without regulator is probably an alternator. Alternators have a built in regulator which could also be at fault.

Edit: 2003 Ford Expedition with parasitic amp draw that would drain the battery over night. Took several hours removing one fuse at a time to locate the parasitic amp draw. Shouldn't take that long to locate the problem on a Cub.

Thanks! Good explanation...will pass it along and when I return from a dive trip (Jan 12), I will follow up.

Apologies for hijacking the thread!
