Excellent, will get the meter out, just wasn't sure where it was located. That is prob's knackered as well, especially if its showing 0% Unless the software doesn't recognise it :) check the connection you may be in luck ! ignition "on" engine "off" should read less than 0.70 volts, as you open close throttle it will rise to max 4.0/4.5 volts carnt find ohm's resistance values, but should remain stable ;)
