15.5V can be accepted as within normal commercial tolerances, as the electrical manual allows 16V. There should be no reason why 15.5V DC should cause the trouble lights in question to illuminate.
The pilot voltage sensing wire referred to connects directly at the distribution box and is shown as "S" (sensing circuit) in the wiring diagram. It does not physically run to the ignition switch. The diagram is a only a schematic, and in any event this circuit should not cause the problem.

John I don't have to guess who, the wording says it all.
15.5 volts is not accepted as normal. No lead acid battery likes to be charged above 14.8 volts. The 16 volts that your
accredited electrical engineer has read in the manual, is referring to the the failsafe 16 volt zener diode that is connected in the regulator circuit to prevent the voltage rising above 16 volts, to protect the cars electrical components, in the event that it no longer can read the battery voltage.
It is the black/red wire in the plug on the side of the alt that reads the battery voltage. If the ignition is on there should be battery voltage on the wire.
