Voltmeter/Countdown Timer

8 . Voltmeter/Countdown Timer

The built-in voltmeter reads the voltage of the vehicle’s battery for enhanced diagnostics and troubleshooting. The voltmeter will automatically read the voltage of any battery (or battery system) when the battery clamps are connected - even if the unit is powered off. The voltmeter will read voltage between ~3V to ~30V. If the connected battery is below 3V, nothing will display. In this situation, it is likely there is a load(s) on the battery, such as, headlights or an AC fan that should be shut off before attempting to start the vehicle. While the unit is on and after a battery is detected, the voltmeter will display the 60-second timeout countdown.

Boost LED

9. Boost LED

Illuminates white when boost is active. If the unit is connected properly to a battery, the GB250 will automatically detect a battery and go into boost mode (LED flashes white when manual override feature is active).

Manual Override Button

10. Manual Override Button

To enable, push and hold for three (3) seconds. WARNING: Disables safety protection and manually forces boost "on". Only for use when a battery voltage is too low to be detected.Learn More.
