Tests batteries,alternators,
regulators, and starters. Direct-from-battery tachometer feature
gives RPM readings without complicated hookups to ignition
system. Built in ammeter/voltmeter capabilities. |
Has its own internal battery; no external power source needed.
Checks charging system at high RPMs and at idle, and stores the data. Results show regulator volts, peak amps, and diode condition. Utilizes wave form analysis when testing alternator diodes; more accurate than “ripple voltage” tests.
The OTC 3131 MinuteMan Plus
Displays cranking volts and amps, indicates
either "Good Starter" or "Bad Starter."Price
