How to Test an Electric Generator
- 1). Check the generator for proper fuel levels before beginning the test. Fuel should be checked every week.
- 2). Remove the dip stick from the generator. Wipe the oil from the stick and dip it back into the crankcase. Check the oil level on the dip stick and fill with the oil specified in the owner's manual.
- 3). Check that the battery terminals are hooked up to the positive and negative line.
- 4). Disconnect the generator from the regulator that powers the home or device hooked up to the generator.
- 5). Connect a jumper cable to the DF connection on the generator. Hook the other end of the jumper cable to the frame.
- 6). Set a voltmeter to the voltage setting (ohm) and touch it to the D+ terminal.
- 7). Turn on the engine of the generator and increase the engine speed. You should read 35 volts at 3000 RPM. If not, have the generator professionally serviced.
