8. The following A.C. voltage readings will be measured on the 3 PHASE GEN IN terminals.
While the C776i is in use, perform the same A.C. voltage reading between the red and
black, red and white and black and white wires. All three voltage readings should be
approximately 90 Vac at 60 steps per minute. See Diagram 6.4.
9. If the voltage measurements are absent, disconnect the three generator leads from the
3 PHASE GEN IN terminals and repeat the measurements in step 8 directly to the generator
wires.
10. If the voltage measurements are still absent, replace the generator. If the voltage
measurements are now present, replace the lower printed circuit assembly.
11. If all of the above test have been performed and the C776i is still not functioning correctly,
call Precor technical. support.
