I turned on the A/C and the voltmeter went into the red. I checked the fuse box in the house, and the guy who put in the service to the TT used two 30 amp Square D fuses. none are tripped and I don't know why the gauge would show in the red. do you think the two fuses are going bad or just not working properly?
Based on the terms you used and your descriptions, I have to wonder if you know enough to understand exactly what is happening. Nothing wrong with not knowing about complicated issues.
