TT Plugin Boost Switch


Recommended Posts


We have added a switch to DI9 Pin 112 and Sensor Earth Pin 27. However when switching we find in one position the system is active but in the other it flashes (switches) itself on/off continuously.

Any ideas? We have set this up on other cars before so something is amiss.

Pictures attached of our setup.

Regards, John

The next test will be to measure the voltage at the Di9 pin with a volt meter.

The Di activation voltage is 1.5V so if the measured voltage is close to this then the DI could toggle.

One option is to use a 12V in and have the internal pullup off.
