Multimeter Usage
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 opera-
tion and durability, Polaris recommends the Fluke Model 73
(PN 2870659), or Tektronix DMM155. See photo at right.
This instrument will provide a digital readout of the measured
value of the test being performed.

V = Volts AC - measuring alternator output
Used to measure AC voltage in an electrical system. AC volt-
age is produced from every coil on the stator plate when a
magnet is passed by it.

Method
1. Connect black lead to Com (--) meter terminal.
2. Connect red lead to V
: (+) meter terminal.
3. Turn selector dial to V
setting.
4. Connect test leads parallel with test component. The
polarity of the leads is not important.
Usage
S Test unregulated voltage output of a stator coil
S Test regulated voltage to the lights and handwarm-
