TM 10-3930-659-20 2-27. MULTIMETER (Con't). CAUTION Before  performing  a  continuity  test,  always  disconnect  the  forklift  truck  battery  ground cable   and   the   circuit   to   be   tested.      Failure   to   follow   this   caution   may   damage   the multimeter. (2) Testing for Continuity. (a) Zero multimeter [see subparagraph (1)]. (b) Connect black and red probes (8 and 9) to both terminals of circuit being tested. (c) Read digital readout (7) and interpret the results as follows: 1. If digital readout (7) indicates 0 (zero), circuit has continuity. 2.If digital readout (7) indicates resistance, circuit Is open. TA706721 2-16
