STE/ICE TROUBLESHOOTING (SIMPLIFIED
TEST EQUIPMENT FOR INTERNAL COMBUSTION ENGINES)
● General
a. This section is applicable only if STE/ICE is available. This section contains information and tests which may be used
with STE/ICE to locate malfunctions that may develop in the vehicle hull. The tests can be used during trou-
bleshooting or after replacing parts to isolate malfunctions, and to make sure that proper repairs have been made.
b. STE/ICE is used primarily with the vehicle electrical system. These tests cannot cover all possible troubles which may
occur. To obtain the maximum number of observed symptoms of the malfunction, question the vehicle crew.
● STE/ICE
Tests and Set-Up Procedures.
a. The STE/ICE testing capability that may be applied to the launcher are tests No. 51, 0-4000 PSIG Pressure Test
and No. 89, DC Voltage Teat.
b. STE/ICE set up and confidencc test (Tests No. 66/60) must be performed prior to performing any tests.
● STE/ICE
Description and Operation.
a. General. The following describes the operation of the STE/ICE system and contains detailed operating procedures.
It is used to test the serviceability of vehicles and to perform primary fault detection and isolation. After the technician
has identified a faulty part or subsystem, he is referred to a paragraph number for replacement or repair procedures for
individual parts.
b. Description and Operation. STE/ICE is used in this technical manual as a measuring device for DC voltage. STE/ICE
is portable and operates on either 12 or 24 volt vehicle batteries or equivalent power source. The STE/ICE system
consists of a vehicle test meter (VTM), a transducer kit (TK), four electrical cables, a transit case, and technical publi-
cations. Only the VTM and cables W2 and W5 are required for STE/ICE tests in this manual.
