Hey guys. I just done the kemo timer mod so i can run metal tip glow plugs safely. I got it so the light turns off after 30 seconds (very touchy adjustments). I have a couple questions for anyone else that has done it.
1. Does the time adjustment vibrate and change the timer at all?
And 2. How do i test for power at the glow plug rail. I have a test light. I dont know how to use a multimeter so hoping a test light will do but where do i connect it?

The car does start no worries but the instructions tell me to check it
