and set multimeter to read V dc.
(2) If multimeter indication is not between 14.99 and 15.01 V dc perform b below.
(3) Move positive lead from TP3 to TP4 (fig. 20) and verify multimeter indicates
between -15.2 and -14.8V dc.
(4) Move positive lead from TP4 to TP5 (fig. 20) and verify multimeter indicates
between 4.9 and 5.2 V dc for serial number 2305A to 2616A and between 5.1 and 5.2 V dc
for serial number 2618A and above.
