NOTE
a.
Main bus voltage should move up from +/- 12.5V to above 13V
when the engine RPM is held above/at 2500 RPM for more than
5 seconds. This is the indication that Alternator B has been
brought online by the ECU.
b.
When the oil is below 50 °C, the oil filter is bypassed due to the
increased viscosity of the oil. Significant throttle settings must not
be used during this period, as it may cause damage.
