Instrument panel switches

New here. I just purchased a 79 42LRC that has been remolded and has several pull switches that do not seem to do anything. One in particular says Fuel Pumps. The motors are Perkins 6.354 with an electrical stop solenoids. There is a shut off button for each engine that when pushed activates the solenoids and shuts off the motor. What is the use of the Fuel Shut off pull switch? It is an electrical type switch and not a mechanical linked switch. Also there are a couple on the fly bridge as well that do not seem to do anything (one does activate the anchor light, and the other the instrument lights only) there are still two others that do nothing or are labeled.

Thanks in advance

Welcome aboard. You will probably have to trace the wires and see where they go. Could be a PO added them so the function could be questionable.

Certainly not unusual to have new systems installed in a 40yo vessel but still have the old ones there because they were a PITA to remove.

Time to get out the 'multi-meter' search for voltage at the switch.
With the engine running and you shut the switch off, does the engine continue to run?
If the engine continues to run, maybe time to get out the 'fox and hound'?

Fuel cutoff switches that don't go to the injector pumps as stop buttons could be for fuel lift pumps or fuel line feeds that have solenoids versus valves at the tanks if there is no anti siphon devices installed.

My LRC has silver pull knobs to operate the wipers. Could some of your switches be for the same? Especially if the wiper motors are Inop - the switches would appear to do nothing.

Have you tried pulling the switches while someone listens in the engine room to see if they hear anything or if anything happens/changes?

Any chance you can ask the PO?
