Intermittent Low Air Pressure Warning Light

[Russ Knight]

Buzzer always works, light works when it feels like it.

Based on the 5-ton wiring diagram from TM 9-2320-260-20, the buzzer and light are fed from the same supply wire (#85), so if the buzzer always works but the light is intermittent, check for loose connections at the #85 supply wire to the bulb, bulb contacts or in the ground wire coming from the bulb to ground.

Thank you sir!

Let us know what you find. I'm betting on corroded bulb connections.

Bulb base looks good. I'll let you know what I find.
