Model Installation and Operation Manual
A Digital Multi-Meter (DMM)with a diode scale is preferred. You should have a RED lead
in the positive (+) input and a BLACK lead in the negative (-) input.
Different meters give different readings on diode tests. KNOW YOUR METER !! Some
meters read backwards due to battery polarity. Test YOUR meter on a known good diode
bridge before performing tests so that you know how your meter will act.
Refer to page 32 for the drive power schematic and semi-conductor diagrams.
If the transistor module is to be tested in circuit, make sure power has been off long
enough for the capacitor banks to completely discharge.
The procedure is the same for in circuit or out of circuit testing. If a component tests bad
in
circuit, it must be tested again after it is removed because of the possibility of alternate
paths when the component is in circuit.
