Years ago when I bought my E15, the controller card #1 had a large mouse
nest on it. Almost all the components had corroded or missing leads on
them. With the wiring diagram in the Owner's Use and Care manual, I was
able to completely rebuild the card, adding wires or solder bridges to
jumper around rotted traces. It worked fine, and is still working.
However, I have an Alltrax controller sitting on the shelf, and if I get
the
time and energy, I will install it. The control circuits on an E-15, even
when working right, still leave a lot to be desired. My E-15 has a heavy
bucket loader assembly on it, and when moving forward may take a while to
come to a complete stop, even using the brake. If the operator selects
reverse while it is even creeping forward, it will blow a fuse.
Regeneration? Having controls that taper down and ramp up would be better
in this application. My current solution is to hit myself in the forehead
each time I forget to wait for the complete stop.
