Q: Can I hook this High Voltage Cable Tester E5 up to a external battery and ground the (-) side of the battery to the engine if using on a non-power aircraft? Cub, Champ etc.
The power source does not have to be the aircraft battery. 12/24 volts are required to test, but it can be from an alternate power source
