(see WP 0193 00).
5.
Reconnect wire 33 to engine oil temperature gage and gage panel to bulkhead wiring harness to gage
panel. Install ground strap (5), two lockwashers (4), two screws (3), gage panel (6), three lockwashers
(2), and three screws (1). Open air inlet doors (TM 9-2350-256-10). Disconnect bulkhead to engine

MASTER switch OFF. If voltage is present, go to step 6. If voltage is not present, repair/replace wire
33 of gage panel to bulkhead wiring harness (see WP 0194 00 for dual voltage; 0195 00 for single
voltage).
6.
