 |

Has anyone replaced the CJ stock low level fuel lights with USA style push to test lights. Looking at the back of the CJ PTT Lights is an enclosed module. Looks like a bit more complicated than re-hooking up a few wires and adding a power wire. [quote][b]

There is no provision in the stock CJ indicator lamps for a PTT circuit. I have replaced all of these lamps (with two exceptions) with standard MS PTT indicator lamps.
The exceptions are:
1. Landing gear position indicators. These are not individual lamps and a PTT circuit and button has been incorporated to test all 6 lamps in each box.
2. Low fuel indicators. The circuit design is not conducive to replacement with the MS PTT lamp. The lamps are energized by a switch in each fuel tank unit that connects the circuit to ground.
I simply added an additional ground circuit through a DPDT, momentary contact switch which allows testing of front and rear, left or right.

Walt, thanks for the info. When installing the DPDT momentary switch, I assume you spiced into the ground circuit coming from the tank at each set of lights?

Greg;
No, that would prevent operation of the lamp from the low level switch since the path to ground would be open at the PTT switch.

Hi Jon;
No diode required for the circuit I have installed. Works just fine. No effect whatsoever on normal operation.
