MinuteMan Plus saves you hours when you’re testing batteries, starters, alternators, regulators, and charging systems.


  • Special AGM test options for accurately diagnosing AGM and spiral (six-pack style) batteries.

  • Can switch between English and Spanish languages with a menu-based selection.

Battery Testing

The way it has been:Your customer brings in a dead battery and you have to charge it up to test it. Then, if it’s a keeper, you have to recharge it. Hardly efficient use of your valuable time. With MinuteMan Plus on the job, you can test discharged batteries down to as low as two volts, and it won’t drain a charged battery you are testing.You won’t waste time charging bad batteries.

Works on all 12-volt automotive-type batteries with cold cranking amp ratings of 100–1500. This includes batteries found in motor-vehicle, marine, agricultural, forestry, and industrial applications. The tester operates from either 110 volts AC or its own internal,  rechargable 6-volt battery. Featres self-calibration, an internal battery check, and an automatic shut-down to reduce power consumption. On certain competitive, carbon-pile load battery testers, the technician must interpret the readings, then make the electrical system diagnosis. With MinuteMan Plus, all you have to do is read simple test results on the LCD display.

Starter Testing

The MinuteMan Plus display shows cranking volts and amps, and indicates either “Good Starter” or “Bad Starter.” Excessive starter current draw can indicate a defective starter. Excessive engine drag, due to tight or damaged bearings or piston drag, can also cause an abnormally high starter draw.

Charging System Testing

Checks the charging system at high rpms and at idle, and stores the data. Results show regulator volts, peak amps, and a diode condition. MinuteMan Plus utilizes waveform analysis when testing alternator diodes, which provides more accuracy than the commonly used “ripple voltage” tests.

Battery Tachometer Capability

Unique, patented direct-from-battery technology gives you tachometer readings without having to make complicated connections to the ignition system. Provides battery-sensing measurements to 4,000 rpm, with 1 rpm resolution.

MinuteMan Plus multi-application electrical system tester Includes: connector cables, internal rechargeable battery, battery charger, instructions and roll-around cart with two additional shelves for other equipment.
