2-14. GENERAL TROUBLESHOOTING INSTRUCTIONS
The troubleshooting makes use of the Simplified Test Equipment for Internal Combustion Engines-
Reprogrammable (STE/ICE-R) and conventional methods for testing and fault isolation.
a. Simplified Test Equipment for Internal Combustion Engines - Reprogrammable (STE/ICE-R).
STE/ICE-R tests are incorporated into the standard troubleshooting test to aid in fault isolation. The STE/ICE-R acts as a
conventional digital multimeter to measure voltage, current, and resistance. It can also measure pressure, speed, compression
unbalance, engine power, and some specialized battery and starter evaluations. The STE/ICE-R is powered by the forklift
battery. The complete system includes a test meter (VTM), cables, transit case, and technical publications. The STE/ICE-R can
make TK mode measurements while connected to the batteries. STE/ICE-R tests are referenced. Certain tests require use of a
transducer from the STE/ICE-R Additional Authorized List (AAL). For STE/ICE-R Vehicle System Diagnostic Checks, refer
to Para 2-18.
b. General Electrical Troubleshooting Procedures.
Remove rings, bracelets, wristwatches, neck chains, etc., before working on any vehicle. Jewelry can
catch on equipment and cause injury, or may short across an electrical circuit and cause severe burns
or electrical shock.
damage to equipment can result.
