1rst, get your hands on the schematics from http://www.elec-trak.org/.

If you open the panel for access to the open relays (this is the back of 
the
dash board, just behind the front batteries, you will see some open relays
and to the very right you will see some cards with electronics on them.
There are two cards, card # 4, and to the right of that, card #3.  Card # 3
has 3 block resistors and should have a little round "varistor" about the
size of a nickel.

What is the condition of the components on those cards?  Look very closely
at the items at card #4. (left card)  It may look ok at first glance, but
look very closely (I used reading glasses) to see if there are any cracked
components.  Also, make sure that card is seated will into the connector.

Let us know how that all looks...

I have an E-20 [model 26AE20AA, serial number DP20045] which is, as far as 
I
can tell, still has its original wiring, although it may have been tinkered
with.  When I purchased the tractor it had dead batteries but was wired 
such
that there would have been  18-volts across the lights and 24-volts across
the lift.

I have only 2 speeds, the slowest speed and what seems like the second
slowest, while the transaxle is in gear.  A check of the hood revels the
front resistor pack is heating up after a few minutes of travel.

When I operate the foot pedal by hand with the transaxle is in neutral I 
can
hear the switches close and a can hear a corresponding change in motor 
speed
for all 8 speeds.

Any thoughts as to what to check first?

Thanks,
Bill
