terminals T1 (45), T2 (46), and T3 (47).
b. Check resistance between terminal N (44) and each of the
other terminals (T1, T2, and T3). If resistance between N
and any other terminal is greater than 1 ohm, replace
c. Check for continuity between terminals T1 and T2, T2 and T3,
and T1 and T3. If no continuity, replace transformer.
e. If checks in steps b and c were good, do step 6.
Disconnect main harness connector P12 from GCU. Check for continuity
If no continuity,
replace wire no.
a. If no continuity, replace indicated wire.

Note AC POWER ON indicator and set AC POWER switch off.
If AC POWER ON indicator was off (before AC POWER switch was set
to off) do step 2. If not, go to step 4.
