Troubleshooting Tips (continued)
With a nominal AC power input voltage (100, 115, or 230, depending on the country), the AC
voltages at the transformer secondary between P3-1 and P3-3 should be 41.3 Vrms.
With a cold (i.e.-room temperature) power transformer, you should expect primary and second-
ary resistances of:
For the 100 VAC version:
between P2-1 and P2-2: 41.8 Ohms
between P3-1 and P3-3: 6.9 Ohms
For the 115 VAC version:
between P2-1 and P2-2: 45.4 Ohms
between P3-1 and P3-3: 6.3 Ohms
For the 230/240 VAC version:
between P2-1 and P2-2: 195 Ohms
between P3-1 and P3-3: 7.1 Ohms
