Electrical Testing
Digital Multitester - The Fluke 73
The easiest and most accurate method for testing
modern electrical components is with a digital
multitester. Any good quality multitester will work.
However, due to ease of operation and durability, Polaris
recommends the Fluke Model 73 (see photo). This
instrument will provide a digital readout value on the test
being performed. Listed below are the dial symbols, their
meaning and what the dial setting can be used for.
J»J|k2870659 ^
Off= Instrument Off
V^"=Volts AC - measuring alternator output
V— =Volts DC - measuring battery voltage, volt drop, etc.
300mv— =Milli Volts DC - measuring small DC voltages
Q=0hms, resistance - measuring component resistance values - testing coils, wiring, etc.
->h=Diode check - checking the condition of rectifier diodes; cannot be used for testing except when the diodes
are out of circuit
A^= Amps AC - not used
A— = Amps DC - used to check battery charge rate, system draws, etc.
NOTE: When using the Amp settings, the red test lead must be moved to the 10A (unfused) socket on the front
of the instrument.
Charging System Testing (Unregulated Voltage)
1. Remove electrical box cover for component access.
2. Turn multitester dial to Volts AC ( ^ ) position.
3. Disconnect alternator-to-main harness connector at electrical box. Connect one of the tester leads to the
yellow alternator wire and the other lead to the red/purple alternator wire.
4. Start engine. While observing voltage reading, increase engine speed to about 3000 RPM. Readings should
be above 20 VAC. If output is low, test stator coils with an ohmmeter. Refer to the wiring diagrams for
connections and resistance specifications.
Do not run engine out of the water for more than 15 seconds as severe engine damage may result from
overheating.
