The heated windsheild is not working, when you push the switch and the timer turns off the relay as soon as you let go of the button. how long should the timer keep the relay on. is it possible the timer is bad.

 

Hi,
the timer should run for about 10 mins. Check the voltage at the input to the timer because there is a voltage sensitive relay in the cct too! If its below 11.5 v (ish) it wont let the heater work.
Hope this is of some help.
