This tool is good. The better way is with an actual load. A carbon pile resistive load test at 100Amps+
*please do not use your tongue, those are for tiny 9V variety.
Be sure to use it correctly, if hooked up over loose or corroded battery clamps, or connection to alternator is corroded, etc, the results won't be accurate. Well they will be as far as what the electrical system is doing but you won't be able to determine if your battery or alternator is bad.
Good heavy duty clamps. When I use a carbon pile load. I disconnect the ground cable. I don't want to overload the alternator. I want to test the battery in an isolated state.
For testing the alternator (with battery connected) I use a DC AMP clamp on meter, slowing adding loads...lights, A/C, Rap music at 11, etc... ......while reading your voltage on a separate DMM. Last test was 90+ Amps at ~13.1VDC
