There are no user serviceable parts in the Curtis 1244 controller. No attempt
should be made to open, repair, or otherwise modify the controller. Doing
so may damage the controller and will void the warranty.
It is recommended that the controller be kept clean and dry that its
diagnostics history file be checked and cleared periodically.

CLEANING

Periodically cleaning the controller exterior will help protect it against corrosion
and possible electrical control problems created by dirt, grime, and chemicals
that are part of the operating environment and that normally exist in battery
powered systems.
When working around any battery powered vehicle, proper safety precau-
tions should be taken. These include, but are not limited to: proper training,
wearing eye protection, and avoiding loose clothing and jewelry.
Use the following cleaning procedure for routine maintenance. Never use a
high pressure washer to clean the controller.
1. Remove power by disconnecting the battery.
2. Discharge the capacitors in the controller by connecting a load
(such as a contactor coil or a horn) across the controller's B+ and
B- terminals.
3. Remove any dirt or corrosion from the power and signal connector
areas. The controller should be wiped clean with a moist rag. Dry
it before reconnecting the battery.
4. Make sure the connections are tight. Refer to Section 2, page 7,
for maximum tightening torque specifications for the battery and
motor connections.

DIAGNOSTIC HISTORy

The programmer can be used to access the controller's diagnostic history file,
via its Diagnostics Menu. The programmer will display all the faults that the
controller has experienced since the last time the diagnostic history file was
cleared. After a problem has been diagnosed and corrected, it is a good idea to
clear the diagnostic history file. This allows the controller to accumulate a new
file of faults. By checking the new diagnostic history file at a later date, you
can readily determine whether the problem was indeed fixed.
