I bought a car recently with an Innovate a/f gauge, it was on the default setting, so i recalibrated it and it worked fine for a few weeks. Then i came to start the car one day and the battery had took a dump, so i bought another fired the car up and the a/f gauge wouldn't come on, so i checked for power to it and the earth, all good. Anyway i took it out and put it across a battery and still nothing so there must be a fault within the gauge. Has anyone ever had this problem or had the gauge apart and fixed it, or do i need to send it back to innovate ?
