    What is this 12mm long 2mm dia glass tube with a coil inside? SOLVED It's a transponder

    You're right. Googling "transponder chip" finds the exact same thing. It's not from my own car as my key works fine. Cheers

    What is this 12mm long 2mm dia glass tube with a coil inside? SOLVED It's a transponder

    I found this on the floor and I'm concerned it might have fell off something I need. Anyone know what it is? It has a tiny coil inside wrapped around a black cylinder.

    Single phase motor reverse rotation

    Single phase motor reverse rotation

    UPDATE. I just sorted the problem of blowing fuses and the motor is rotating in the direction I want. I fitted new bearings to the motor a couple of days ago and noticed straight away that the motor was more stiff to turn and wouldn't turn freely if twisted by hand. I thought that was just the...
