Good work, Sean. Including the failure warning may prove useful; I've had
several LOP switches quit, leading to peculiar problems. For example,
after one engine change it would run only a few yards or a few miles.
Turned out to be the boost pump, which was on the LOP switch, was
partially or completely filling the fuel accumulator dependent on how long
it took to start the engine. The high pressure pump was, at that time, not
on the LOP, only controlled by the computer. Had me baffled for a couple
of days. If I'd included a light, as you have, the failed LOP would have
been indicated instantly.
