3-23. STARTING CONTACTOR (cont)
To avoid excessive heating, do not energize coil for more than 2 minutes at a time.
Connect a variable dc voltage supply to coil (33). Use a multimeter and measure voltage. Check that pickup
voltage is 36 V dc maximum and dropout voltage is 3 to 16 V dc. If voltage values are not as specified loosen
jamnut (30) and adjust core stop (32) at top of coil frame (28). Tighten jamnut.
Energize and deenergize relay and check that there is no hesitation during pickup or dropout.
Set battery switch to open position. Manually operate interlock contacts. Use a multimeter and check resistance
of contacts for infinity while open and continuity while closed.
