    AutoTrack II

    I have AutoTrack II on my American Hill Climb 8 lane track for 20 years now and I like it ,I guess because I'm used to it but I have noticed the lap counting system has a problem counting laps on cars that the motors have more then 45 degrees timing ( they don't count ) does anyone have any ideas why ? It's always been like this but I haven't had racers with that much timing in their motors until recently so now it is a BIG problem. Thanks for any help, Dom

    Hi Dom.

    Yes, we figured out what was going on with the high-timed motors in a thread about LapMaster.

    However this surely applies to any (dead-strip based) lap counter system.
    The remedy is to insert a diode (i.e. 1N4001) in the wire coming from the deadstrip.
    The diode needs to face the correct way. If you insert it in the wire from the right side of the braid it should have the circle indication facing away from the track.
    If you insert it on the left side braid, the circle should point towards the track.

    If the diode is not enough, you might need to add a 10 uF capacitor to the wires after the diode.
    Best regards,

    Hi Carsten, Thank you very much for the fast reply, I will try the diode as soon as I get some, if I need the capacitor I would put it across the two wires coming from the dead strip but after the diode, Do I understand that correctly ? Thanks again , Dom

    Yes, that is correct.
    The capacitor also has a positive and negative side. The positive needs to connect to the wire comming from the right side of the deadstrip.
