Do not hipot (or merger) the control. Unless the
terminals of each semiconductor and card are
connected together, the control may be damaged.
Refer to control manufacturer before hipotting.
Use a lead-acid battery with the voltage and
ampere hour rating specified for the vehicle. Follow
normal battery maintenance procedures,
recharging before 80 percent discharged and with
periodic equalizing charges.
6. Trouble-shooting Instructions
Trouble-shooting the EV100 LX/LXT control should be quick
and easy by following the instructions outlined in the following
status code instruction sheets.
If mis-operation of the vehicle occurs, a status code will be
displayed on the Dash Display for vehicle equipped with a
Dash Display or by plugging a Handset into the logic card’s
plug “Y” location and then reading the status code.
With the status code number, follow the procedures outlined
in the status code instruction sheets to determine the
problem.
Checking and replacement of components are also outlined
in sections of this instruction book. Please refer to these
sections as needed.
The same device designations have been maintained on
different controls but the wire numbers may vary. Refer to the
elementary and wiring diagrams for your specific control. The
wire numbers shown on the elementary diagram will have
identical numbers on the corresponding wiring diagrams for a
specific truck, but these numbers may be different from the
numbers referenced in this publication.
NOTE! Due to the interaction of the logic card with
all vehicle functions, almost any status code
or control fault could be caused by the logic
card. After all other status code procedures
have been followed and no problem is found,
the logic card should then be replaced as the
last option to correct the problem.
