Fuel Pump Operation Indicator Light
This MS25041-4 series mil-spec indicator installs in the panel at any location convenient and viewable in scan for the pilot. Its purpose is a tell-tale for the fuel pump “on” operation. Operation of the bulb-test function is activated by depressing the lens; dimming by twisting the lens clockwise.
Added wiring consists of a circuit to the existing 5-amp indicator lights’ circuit breaker and a ground circuit for the bulb-test function; and a circuit to the fuel pump toggle switch. Kit contents include complete requirements for the installation: the MS25041-4 indicator properly assembled with MS22759/16-20 Tefzel wire marked per your airframe specification using the Kingsley hot-stamp process. Marked wire for the added circuits, terminals, bulb, nylon cable ties for security, instructions and schematic are also included. Expect an experienced installer to do the installation in 1 to 1-1/2 hours.
