CORRECTIVE ACTION Continued
Steps 10 through 14 are the same for both left and right preheaters and fuel solenoids. Perform 10
through 14 as necessary for each side.
10. Remove powerplant (see WP 0098 00). Reconnect bulkhead to engine bracket and rear fuel tank
transmitter wiring harness to engine disconnect. Disconnect engine wiring harness from manifold
preheater ignition unit. Place red lead of multimeter in socket A of wire 486 and black lead to ground.
Turn MASTER switch on, push START and manifold preheat switches, and check for voltage. Turn
MASTER, START, and manifold preheat switches OFF. If voltage is present, go to step 11. If voltage
is not present, repair/replace wire 486 of engine wiring (see WP 0207 00 for dual voltage; 0208 00 for
11. Place red lead of multimeter in socket B of ground wire and black lead to ground. Check for continuity.
If continuity is present, go to step 12. If continuity is not present, repair/replace ground wire of engine
wiring harness (see WP 0207 00 for dual voltage; 0208 00 for single voltage).
