Hi Michael,
Thanks for your thoughts. Sorry to hear about the problem you had but
glad its resolved.
You may have it that its the motor brushes.
How difficult is it to check this?
I guess I can get the motor off easy enough.
Any tips on getting to the brushes?
Thanks,
Zack

Richard,
I had an E-15 that bucked, it was a battery intercell connector.
(internal part of the battery) The headlights would blink and the charger
would surge. Finally found it when the battery exploded. Cracked the
battery case at the top seam. I broke open the battery top and found the
broken intercell connector. It was a bad lead casting, alot of little
beads, not a block of solid metal. I also had help and a ton of safety
equipment, aprons, face mask, rubber gloves, glass trays. Problem did
not return after the battery was replaced.
I would also check the motor brushes, they maybe at end of life. Worn
out.
Good luck Mike DeLiso
Thanks guys but its not the belt.
The power use gauge fluctuates in perfect harmony with the bucking of
the tractor.
Opened up the behind the dash where the fuses are but found no card(s)
on my E12. Either I'm looking in the wrong place or there are no
cards.
Does anyone have an E12 service manual and/or any ideas on where to go
from here?
Is it a bad connection somewhere in the field weakening circuit or
possibly something else?
Thanks for any specific suggestions I might be able to follow and try
out.

You will need the service manual from Bill Gunn or ask on the mail
group. My E12 has no circuit cards. If I get a chance I will look in the
service manual and try to figure something out for you. I need to fix My
E12 as I blew a diode (again) that's in the reversing circuit. The
tractor only runs in reverse right now. The E12 is my back up tractor
and I have not needed it this summer. I use the batteries in it as a
backup for the UPS system for the house. I have a cord and connector
system to connect between the tractor and the UPS battery bank. They all
use the same golf cart batteries so it's a good match.
With out the service drawing it's hard to figure anything out about the
wiring on the tractors. Even with the drawings it's still hard!

Hi Dwight,
Thanks for the response. I am a novice at this having just gotten the
E12 in June and have little background experience.
Anyway, went out and tested it and yes, the load meter bobs up and down
corresponding to the movement of the tractor.
Was able to look under and see that the drive motor pulley was clear of
the wiring, so that, at least, eliminates that.
As to field voltage, I went to the "Home Owner's Service Manual" that
came with the tractor and tried to find info on field weakening. Found
some info for the E12S that shows a card #1 and a FW connection. But
when I opened my E12, I couldn't find the card #1. Doesn't look like the
E12 has such a card or its located some place else.
Can you give me any specifics on where to look for a loose connection?
I think the reverse relay should be on the back of the dash panel on the
left side (away from the speed control). What do I do with this reverse
relay when I find it?
Don't be afraid to insult my intelligence by being overly specific.
ASSUME THAT I KNOW NOTHING.
Thanks very much,
Richard "Zack" Zachary

Zack,
What is the reading on the load meter? Is it going up and down with
the
jerks? It may be a wiring problem or a contactor/relay problem. I
wonder
if your field voltage is steady. The reversing relay may be the place
to
start. Also is the motor drive pulley wearing through the wiring
harness under the frame?

My tractor bucks some. That is, the ride is herky-jerky. It seems
worse in reverse than forward.
Is there some adjustment I can make?
Did I tighten the drive belt too much maybe?
Thanks for any advice you may be able to give.
