Press-To-Test Lamp
My Press-To-Test indicator light for my landing gear has three lugs on the
back for three separate wires. Can anyone explain the appropriate hookup for these three lugs so that I'm sure to hookup the correct wire to each of the lugs? Thanks! |

One goes to the + bus, one goes to ground, one goes to whatever switch illuminates the light. The Press to Test feature needs power to light the light. |

If the lamp assembly you are using is an MS25041 type, the solder lugs are numbered. If you have a metal airplane, or intend to use negative ground busses at various locations in the airframe, then wire the lamp assembly as follows: Lug 1: + Lug 2: to switch(es). If you are only using one gear-down indicator, wire the switches in series, with the last switch having one lug connected to ground. If you have two or three gear down indicators, connect lug 2 of each to a SPST NO switch, and the other switch lug to ground. Lug 3: to ground. The lug numbers are normally stamped on the lugs, or nearby. If you cannot read them, looking from the back, with the center lug (#1) on bottom, #2 is on the left and #3 is on the right. Hope this helps. |
