measure the voltage.
Electric characteristic
Voltage ranging between 14.0 and 15.0V at 5000 rpm.
Maximum current output check.
- With engine off and panel set to "ON" turn on the lights and let the battery voltage set to 12V.
- Connect ammeter pliers to the 2 recharge positive poles in output from the regulator.
- Keep the lights on and start the engine, bring it to normal speed and read the values on the ammeter.
With an efficient battery a value must be detected: > 20A
