Re: (ET) E12 Stuck in Reverse/B145 traction motor overheating

[RJ Kanary <rjkanary nauticom net>]

I'm lost. [ Not all that difficult to do.  :) ] The  model number you 
have provided doesn't fit with the information in the Homeowner's 
Service Manual.

By way of review:

E-12 models AA & BA are the E-12 S

Basically a neutered E-15 AA to HA with three armature controlled speeds 
only, electronic controls and the problematic field reversing scheme for 
directional control. Has smaller traction motor, smaller tires and only 
one drive belt.Possesses three armature controlled speeds in Reverse.

E-12 models CA to HA.

Uses armature contactor reversing scheme.  Has three armature resistor 
controlled traction motor speeds. Possesses only two armature controlled 
speeds in Reverse.Has a centrifugal switch in the traction motor to 
delay the closing of armature resistor contactor 2A to delay third 
speed. This can be bypassed by pushing the Power Pulse button on the 
dashboard.Appears in two chassis types, short wheelbase for the front 
mount mower, long wheelbase for the mid mount mower.


Based on these descriptions, which one do you have ? <VBG>
