I think My SOTF Switch is not working..Updated 2 years ago
To verify the functionality of your SOTF ( switch on the fly ) switch please try the following
1 ) View this link : https://www.fishtuning.com/troubleshootingswitches
Check to see if there is a button on the back of the switch. If so, with the key on, press the button at each position and note the results. When you press the button a small LED may light up. It should be brightest in position one (fully counter-clockwise) and dimmest or off in position five (fully clockwise). Except for some Fords which will be bright in both positions one and five. There should only be five positions. If that happens then the switch is probably installed correctly and working properly.
If you still think it's not working, or you have a switch without a button on the back, you can test the switch with a voltmeter across the wires with the key on. You can get to the wires from the back of the switch. Starting in position one you should see a voltage, most commonly 5V DC or so, and then as you go from position one to position five, the voltage should drop. If that happens then the switch is probably installed correctly and working properly. If instead of ~5V in position one, you get ~7V, you have inserted at least one of the wires in the incorrect hole. this seems to come up in LBZs and LMMs. If that's the case there is a picture lower down this page showing the correct location of the wires in the LBZ/LMM connector.
In shorter terms
Check if the light is present on the backside of the switch
Use a voltmeter and see if you change the power levels if the voltage drops. It should decrease in increments.
2. Check your connections
Make sure the connections you have made are correct. No loose cables or anything on that sort.
3. If you have checked both (1) and (2) and you have verified that the switch is NOT working based on our troubleshooting methods,
