I have the rad fan of my car set up so it can be switched on if in traffic-jam and the coolant temp starts rising
on the rad, the wire I can cut in to (easy option) is a negative feed and where I have the on/off switch there is a posative feed so I use a relay to swap the posative trigger in to a negative trigger, thats all OK and works fine, like this:
so no problem with this setup, but would like to improve on it
my next step/plan is to insert a delay off relay between the on/off switch and the negative output relay, so once I press the switch (on the time delay relay) it will feed the fan for the set duration then cut the power, this way I can power the rad fan of the car and can forget about having to switch it off very time I power the fan manually
will my setup in this diagram work, the way shown?
or if you can point me in the right direction, where I'm going wrong please?
Power from the battery is already fused from the fuse box but haven't shown it on the diagram (error)
many thanks
