  • Incandescent Ignition Bulb?

    Anyone know what the Moss part number is for the ignition warning light is fir a 73 TR6? Can’t quite narrow it down with the Moss search function. Doing some dash work so I might as well replace the LED that is in there. It works, but in an odd way.

    It's this one

    It has the standard E10 base if you want to source it locally.

      Thanks. That’s an E10 bulb, correct?

        Yes, I must have been editing with that when you were asking.

          Ok, thanks, found some in my box of bulbs. Now, does anyone have a clever idea for getting the thumb nuts back on the oil gauge without dropping them into the black hole known as behind the dash?

            That's a good one.
            Remove the driver seat (2 nuts & 2 bolts), lie on your back with legs stretched out & head in footwell, have a trouble light on the gauge backside, take some deep breaths and wiggle your arm into position with the nuts.
            You could remove the front screws from the wood dash, and tilt it backwards, but it's tricky getting those screws back in place.

          I'm not that knowledgeable about the LED's, but doesn't the filament bulb provide sensing for the alternator?
          It provides the 12v to the alternator when the key is in run, which allows the alternator to charge.
          Or, am imistaken-Again? I made many changes, and used a 560 ohm resistor in that circuit for just that purpose.

            Yes it does. With the LED bulb I had to rev the engine to about 2300 rpms to get the light to go out and the charging system working.(which apparently it did as the battery is four years old and has never been on an external charger). So I’m going back to incandescent, though the LED was very bright.

              • That may be next. Somehow I got the nuts and bracket off thru the ashtray, and I still have numerous lacerations on the back of my hand and fingers as evidence.
