I have a question for all of you that have done the alltrax conversion on
your tractors. I am almost finished with the E20 conversion and am
wondering if any of you have kept the CB-3 breaker in your conversions?
The CB-3 is an internal breaker in the main motor that has the two leads
#5 & #25 coming out of the motor connector plug along with the field wires
#62 & #36 on the motor. If you have kept this internal breaker, how did
you end up wiring it? I believe that the Alltrax schematic doesn't show
it, nor does the controller seem to need it to function. I'm just leery
of snipping too many wires that are not required for this installation to
function.
Thanks,

I said to wire it in series with the Brake Switch (also the Seat Sw. &
Key SW.).
look at the wiring diagram for the Alltrax. You will see the SEAT SW.,
KEY SW., & BRAKE SW. are wired to the MAIN CONTACTOR. Turning off any of
these will turn off the power to the Alltrax unit. If the tractor is
moving it will just coast to a stop, NO FIELD POWER, NO PLUG BRAKING, &
NO STRESS TO THE MOTOR OR CONTROLLER. I Put the Over Temperature Sw. their
because there is no over temp safety in the Alltrax unit. So why not use
it? besides it is close to the brake switch and was wired to it before.
He did not ask about regen, series motors or 375 volt circuits in cars.
Some times you guys get so tecked up that you just confuse the people
asking the question.
I am sorry if I offended anyone, that is not what I am trying to do here.
Thank you
