and remove OBC.
Onboard Computer Installation
1. Install the OBC onto the component mounting plate by aligning the two holes on the OBC face plate with
two holes on component mounting plate. Slide OBC down and align heads of self-tapping screws (3) with
smaller part of two holes in OBC face plate
(Figure 12-10, Page 12-12)
. Tighten screws to 5.5 ft-lb
(7.5 N·m).
2. Connect wires
(Figure 12-9, Page 12-9)
. Make sure all connections are fully seated and boot on gray
sense lead is properly seated.
3. Install electronics module cover.
See Electronics Module Cover Installation on page 12-5.
4. Place the Tow/Run switch in the TOW position and connect the battery cables, positive (+) cable first.
Tighten battery terminals to 110 in-lb (12.4 N·m) and coat terminals with Battery Terminal Protector
Spray (CCI P/N 1014305) to minimize corrosion.
CHARGER RECEPTACLE
See General Warnings, Section 1, Page 1-1.
The charger cord, plug, and receptacle are wear items and should be inspected daily. Visually inspect them
for cracks, loose connections, and frayed wiring; they must be replaced when worn or damaged. If charger
plug or receptacle show signs of corrosion or the plug is difficult to insert or remove, the receptacle contacts
and plug terminals should be cleaned with a good electrical contact cleaner or lightly sprayed with electrical
contact cleaner. The plug should then be inserted and removed several times to ensure ease of insertion,
ease of removal, and good electrical contact.
Testing the Charger Receptacle
See Test Procedure 12, Section 11, Page 11-33.
See also the appropriate battery charger maintenance and service manual.
Charger Receptacle Inspection
Inspect the receptacle for cracks, loose connections and frayed wiring.
NOTE: Disassembly of the charger receptacle, for the purpose of removal or installation, is not recom-
mended.
