Dennis,
Sounds like you need to get yourself an HSM. Has everything you need to know in it, and then some. I believe it is available for download at either Elec-Trak site and Geo's My Elec-Traks site. Or, I have 3 or 4 spares I could sell you.
From left to right (if sitting on the seat) on the relays : RTN, 2AH, RTN R, CC
3 Contactors L - R : Forward, PTO, Reverse
Plastic Solenoids : 1A, 2A
RJ is right, the loss of upper speeds indicates the 2AH circuit has failed. Although, the loss of forward altogether indicates the RTN circuit may have a problem. I would start by checking the F/R switch, then the RTN relay. Each one you can check with a meter after disconnecting the wires. The RTN relay you can check the NC contacts and then physically push down on the fingers to check the NO contacts.
Was the CC light coming on when you reach the 2nd speed?
Hope that helps.
Chad Bush

RJ;
Thanks for the response.
I'm pretty sure it has (2) of the plastic type relays. Is this the 2AH ?
To help me, do you know the Label Names for all of these relays.
(4) of the reed type.
(3) of the Metal Silver Contactors
(2) of the plastic type.
I need to do some more investigation over the weekend.
Thanks;
Dennis

The loss of upper speeds, and the use of the Cruise/Power Pulse button
leads me to believe there is an issue in the 2AH relay and /or wiring.
Is there any indication of current draw when Forward
motion is attempted? If so, there is likely a field/wiring issue. If
not, do you hear the armature reversing contactor pull in? If you do,
and no current draw is evidenced, suspect a failed set of high current
contacts in one of those.
This tractor uses the single coil,plastic reversing
contactors, does it not ?
