model 86
 

Hi again...
I'm pretty sure that my 86 isn't charging. Is there anything to check before I start swapping parts out?
The engine starts fine with the starter/generator so that means it is good right? if it works as a motor it will charge right?

Also on another note... I'm hoping to use this tractor to till my garden in the spring. What all will I need to get a tiller on it? Is the 8hp Kohler enough to run one?

First....do you have ....
 

A voltmeter...even a $4.99 cheapie will work.

yes i have a voltmeter

Check across the battery terminals with the motor running full speed and let us know the reading.

If you haven't already down load and print these manuals. They will have almost all of the answers to your questions in them:

Measure across the output of the S/G to ground....what do you see there?

ok... sorry too be so long in responding...
sitting static the battery has 13.6 volts, running wot it has 12.8 volts and checking at the generator wire i dont seem to be getting any voltage...
i took everything apart and cleaned the connections and re assembled.. but it diddnt help.

86 not charging...
 

ok my 86 isnt charging and it seems to be the generator... are they hard to overhaul? is it usually just cleaning the armature enough to get them going again? or do i have to send it out?

i too have an 86 that had a bad s/g. it spun, but put out nothing as far as charging. i opted to take it apart and clean the armature, and all points of contact. it was very rusty in there from sitting out in the elements. take your time if this is the route you choose. a fine wire brush, perhaps the kind you'd use in cleaning the nozzle of a spray gun, electrical contact cleaner, an air hose, and a good set of eyeballs. make sure the "a" and "f" terminals are not broke.
this took me about 2hrs. to clean and reassemble. you may need an extra pair of hands. the s/g has been performing flawlessly since then. also make sure your belt is tight enough, any slippage will prevent a low or false reading on the meter. this is what i did on mine. there may be some things i overlooked. i'm sure others will respond. good luck. keep us posted.

Careful that you don't damage the insulation on the windings on the armature and case as you clean, especially if you clean them with a wire brush. A little surface rust inside the case doesn't hurt anything, as long as the armature spins freely. What needs to be clean is on the armature where the brushes run. I'd clean that part with a emory cloth (not too heavy grit, though). I'd also clean up any rust stains on the bearing shafts with fine emory cloth.
