Step 1 – Check the Connections
Loose wirings or improper terminal connections are the most common reasons behind the starter generator not charging the battery.Also, you should conduct a thorough check of the terminal connections of the starter generator with other parts.

Step 2 –Short the Green Wire Manually
If you’ve checked all the wires and they’re connected as intended, then it is time to manually short the green wire to ground. This is done to conduct the full field test. The full field test determines if the starter generator is working fine in terms of the voltage generated at the battery terminal.

Step 3 –Apply Full-Field Current
After shorting the green wire to ground, you need to apply full-field current to shoot up the battery voltage to 15-16 volts.
You have to ensure that the full field current is applied only for the time taken to record the full-field voltage because the high voltage is enough to damage the battery.
If the voltage is 15 or 16 volts, the problem is with the voltage regulator. If not, the starter generator is faulty.
