- Disconnect both leads (D+ and DF) from generator. Connect terminal DF of generator to ground (D-).
- Connect positive lead of voltmeter to large connector (D+) of generator and the negative lead to the D-terminal.
- Run generator briefly at the following speeds. The voltage supplied by the generator must be as follows:
