I received the fuses finally.
None of the three were blown.
I did replace them but there was no change.
The readings for N1, N2, and T1 remain essentially the same.
If your voltage readings to neutral are still as indicated in your previous post:
T1 = 3.6
N1 = 106
N2 = 122
it sure appears that the T1 and N1 fuses are blown. Another possibility is that the N1 leg is open upstream, but this would result in roughly half of the circuits in the house without power and 240-volt loads (stove, water heater, air conditioning) not working at all.
With your voltmeter on AC volts and the transfer switch in the normal utility position measure across each fuse, one probe on each side of the fuse. If the fuses are good you should see zero volts or certainly much less than one volt.
Also check N1, N2, T1 from the top side of the fuse, the side not connected to the generator, to neutral. Also measure from these points to ground. All of these measurements and those from the bottom of the fuses should be approximately 120 volts AC.
Look at the small wires coming to the top of the fuseholders to make sure that they are tight. If you aren't comfortable working on this, call your local dealer or an electrician. With the low voltage on T1 the battery in the generator will drain in a day or two and if left in this condition for a lengthy period it will be damaged.
Also if possible inspect the wiring between the switch and the generator for damage or water intrusion.
