A Must Have For Battery Voltage Checks/Electrical Tests/Home Repairs

Recommended Posts

DVM Clamp Meter

AstroAI Digital Clamp Meter, TRMS 6000 Counts Multimeter Volt Meter with Manual and Auto Ranging; Measures Voltage Tester, Current, Resistance, Continuity, Frequency; Tests Diodes, Temperature


Any decent clamp meter will work.

Clamp it around your negative battery cable, have someone start the truck. Log the amp draw. Easy way to check a starters condition. Do it at the same temperature for most accurate data.


I have one of these for ease of use. Very accurate.

INNOVA 3721 Battery and Charging System Monitor


Plug this into your power plug and monitor your battery.
