Follow these steps:
Check V as per Power Output Evaluation (Section 7) and record in the log.

Compare measured voltage with required V
proceed as follows:
a) If measured voltage is more than 0.2 V above required V
The fuel pressure must be reduced. Proceed with Routine Service, Section 9.1.3.
Remember to adjust the fuel pressure during restart or before leaving the site.
See Adjustment (Section 8).
b) If measured voltage is within 0.2 V of required V
The TEG is functioning well and requires only a routine check. Proceed with
Routine Service.
c) If measured voltage is more than 0.2 V below required V
The cause must be determined. Refer to the last entry in the TEG Performance
Log. In the log, check if the TEG was left operating at the correct V
