Battery was bad so has new battery--got new battery and used the tractor for few couple of hours--disconnected one battery cable to be sure no drainage would take place..went back yesterday, connected battery cable--won"t do anything....tractor is 30 miles from me so that is the first disadvantage--anyway told my Dad to check the voltage of the battery and to check all connections at starter, solenoid, ground cable. Has new battery cables--paid outrageous price few months ago for the original type heavy positive cable and braided ground cable..What am I missing?--Thanks for any suggestions..

Was it charging while running? What was the voltage when your Dad checked it?
The tractor can't really drain the battery while its disconnected so while unlikely,
maybe it wasn't fully charged when you got it and two hours of running
without it charging ran it down.
Also possible you got a bad battery. You could put a load tester on it or have the
parts store test it.

Just a guess from you description of the cables, did you hook the battery up backwards(won t charge but will run)6V is POS ground,NEG to the starter(solenoid)

My Dad called me the other day when he was going to install the new battery..He has always known to do the pos ground thing but he wanted to be sure..so I think he does have this hooked up right--will check though-Thanks

I went last weekend and like a dummy took my digital meter so could not really check the generator output correctly but my Dad took the gen. to a local shop and they said it was good--don't know but surely they checked the output. Dad knows the guy so I think he would have done the whole test-said brushes looked good and bearings were good...like you said, maybe a bad battery or weak off the shelf--they probably don't sell too many 6 volt batteries.---anxious to see what he says the voltage checks across the battery now that it has sat just a few days disconnected..Thanks for the help-will keep you posted.

no need to take a genny in to check it.. you can motor and full field it at home easy test.

also.. ditto what royse said.. was it not charging and ran bat down running... with cable off there should be no draw..

Tom,
If the battery checks out I would recheck the contact between the new cables ends to terminals and ground. Last year I thought my connections were good but the positive ground had corroded and would not even power the lights.
Do you have a working ammeter? If so, have you noticed if it is charging? May wish to check the belt tightness too.
Hope this helps!
Mr. T. Minnesota

wouldnt taking the cable off make the gen loose its charge and need to be re excited??? so when they put the new batt in it wasnt getting any charge??

what do you think happens when you turn your tractor off?

the generator stops charging and the cutout relay opens, disconnecting armature from battery.. thus the 'cable comes off' any time the tractor is not running.

when the cutout opens, it's not hooked to the battery.

the field pieces keep a residual magnetic charge.. that is how the genny bootstraps itself up....

if the field shoes are changed or the genny is substantially repaired or dropped alot or sat for years or otherwise demagnatized.. then you need to re-flash it..

Stopped by my Dad"s place today. Connected the battery cable, put it in neutral-turned on the key and hit the starter button..Fired up like it always has..Maybe he just didn"t have the shift lever exactly where it needed to be---killed it and fired it up several times..Just hit me that I should have polarized the generator and I didn"t..reading across the battery with it running it showed only 6 volts...he said that the generator/starter shop guy did check it for proper voltage output and he said it was o.k.
