The eTriFlex 3370 uses a TEC 2401 series microcontroller as a precharge
controller (T6) to manage the precharge function; refer to
T6: Precharge
Controller (Model 04590) (page 5–17) for T6: precharge controller operation
notes. The precharge controller is located under the hood attached to the back
of the center mounted battery assembly. Power for the precharge controller logic
circuit is available when the key switch is set to the O
N
position (switched). The
logic circuit is protected by a 3 Amp fuse. Power for the precharge controller
outputs is available when the logic relay is energized.
Note: If the precharge controller (T6) is replaced for any reason, the machine
software must be updated; contact an Authorized Toro Distributor for assistance.
Testing the T6: Precharge Controller (Model 04590)
Although there is no method to test the solid state circuitry built into the controller
directly, some aspects of the precharge controller operation are visible using the
InfoCenter Display; refer to
Using the InfoCenter Display for Troubleshooting
(page 3–39) .
1. Park the machine on a level surface, lower the cutting units and set the key
switch to the O
FF
position.
2. Set the function control switch to the N
EUTRAL
position.
3. Sit in the operator seat and set the key switch on the O
N
position.
