To check you need:
Bring the engine up to operating temperature and turn it off (coolant temperature 80-90°С).
Turn off all power consumers.
Check output voltage (400-1000 mV).
Set the transmission to neutral, apply the handbrake. Set the automatic transmission to position P.
Check ignition timing.
Remove the jumper wire to set the ignition timing.
The engine should run for a few minutes at idle speed. Compare the idle speed with the required value: 850±100 rpm.
Attention: Connect all measuring devices only with the ignition off.
