I have a 3-phase, 480V generator that is running but offline. The Voltmeter reads as follows:
1-2 = 140V
2-3 = 480V
3-1 = 140V
Shouldn't these all read 480V? The ammeter reads zero on all three phases. I noticed the voltage differences after I went to replace the "Generator Power Available" indicator bulb and it burned out the second I installed it.
