CHECK CURRENT DRAW
Check current draw of hold-in winding by connecting
a variable source of voltage (in series with an
ammeter) to the switch terminal of solenoid and
ground. Ammeter should read 14.5-16.5 amps.
10
volts. To check the current draw of both mdings,
ground the solenoid motor terminal and connect a
source of voltage (in series with an ammeter) to the
switch terminal of solenoid and ground. The ammeter
should read 4147 amps. 10 volts.
CAUTION: Either of the above checks must be
completed in a minimum length of time to prevent
overheating solenoid windings. Heating will cause the

CAUTION: Terminal studs have welded lead connec-
tions; therefore be extrekly careful not to twist during
removal of nuts.
If solenoid contacts are slightly burned or ditty,
contacts should be cleaned. When contacts are badly
burned, burned parts should be replaced.
ASSEMBLE
1. When assembling cover on solenoid, make sure the
terminal studs are properly positioned in cover. The
cover gasket must be centered under cover to insure
proper sealing.
2. Secure cover with screws and install nuts on motor
and switch terminals.
CAUTION: Be sure to install all insulator washers
under attaching screws and nuts.
