Relay Switch??

Don/Ed...

Do you guys have the wiring diagram for the therostatic switch with a 30A relay for a Spal fan??

I have the manual switch working fine but found a place for the thermo switch and would like to use it and have the manual one for an "override"

Thanks,
Jack

Jack, this is the way I wire the relay.

The relay terminals have #'s 30, 85, 86,and 87 stamped next to them.

#30 goes to the positive terminal on the fan. Run the other fan wire to ground.

#85 connects to wire 151 or an ignition power wire.

#86 runs to the temp sender.

#87 runs to the circuit breaker power side or direct to the battery.

To hookup the over ride switch, remove wire 161 from the switch and replace it with a ground. The other side of the switch has wire # 157 which you can hookup to terminal #86 on the relay.

Wire #151 and #157 run along the drivers side frame rail close to the upper control arm.

Thanks Don!!! That'll make it easier than the ole "Hit-n-Miss" procedure!!

I have the instruction sheet that came with it somewhere....Must be in a well guarded place cause I CAN"T FIND IT!!!!

How's CR-II coming along??

Good Luck!!

Thanks Again,
Jack

Hey Don!

Where do you like to mount the relay itself?

Thanks,

Dwain, anywhere that's good for easy access. I either mount it on the left front fender liner or under the dash on the passenger side.
