ELECTRICAL GENERAL MAINTENANCE INSTRUCTIONS - CONTINUED
MULTIMETER USAGE - CONTINUED
Before performing a continuity test, always turn master battery switch to OFF position and disconnect cir-
cuit to be tested. Failure to follow this caution may damage multimeter.
Testing for Shorts. A short (or short circuit) occurs when two circuits that should not be connected have metal-to-
metal contact with each other. A short also occurs when a circuit that should not touch ground has metal-to-metal
contact with ground.
Connect black probe (49) to one circuit and red probe (50) to either a ground or another circuit.
Read digital readout (42) and interpret results as follows:
(a) If digital readout indicates 0 (zero), circuits are shorted or circuit is grounded if testing to ground.
(b) If digital readout does not indicate 0 (zero), circuits are not shorted.
(c) If digital readout jumps or flickers, circuits are shorted or grounded intermittently.
