Ok, that might work on old none ECU (not many electronic devices running) but on modern vehicles in last 20 yrs I think you'll find alternator is always outputting some amps as just ECU, fuel pump, (bare min to run) is 15+amps .
On OP , not sure what loads that uses with nothing running (lights, fan, radio etc )
