I used to control my electric fan direct by a toggle switch w/30 amp relay but wanted to alter that a bit and install a thermostatic switch with an overide toggle switch set up. I failed on both ends, scratching my head, and need some help. Here's what I've got or where I'm at:
1. Thermo switch has two male ends on it. I mounted it at the water pump and will note i used plumber tape on threads. Thermo Switch is supposed to activate fan at 185 degrees.
2. I ran relay post 85 ground wire to one prong on the thermo switch. On the second prong of the thermo switch I grounded it to the battery.
3. Get motor up to 200 degrees and the electric fan never came on.
I'm not worried about the override toggle switch at the moment as my first concern is to just get the darn thermo switch to do its job. Any ideas or advice? Did i go wrong somewhere in the above info? Need help. Thanks, Robert.
