    Default Triggering circuit to ground

    Hi there,

    I know this is a strange question since the smartwire is there to provide power to a circuit on certain conditions, but I have a need to ground a circuit when it's triggered by certain conditions (GPS speed over 10kph for instance).

    What would you guys suggest as the best way to achieve this ?? I was hoping that the smartwire could trigger to ground somehow ??

    I would say the simplest way would be to use a small size 12v relay.
    Make the Smartwire switch the Solenoid, then connect then input of the relay to
    to ground so when activated you will have a ground output.

    Or a resistor and a NPN transistor if you want a tiny package.

    Thanks JMG.....yeah I figured that might be the only way, but thought I'd ask the question here for Racepak to answer in case there was some other "cleaner" way......

    I'm not sure why I expected a reply from Racepak staff but was worth a try !!

    Thanks again mate.
