Aux. fan switch on a spf.
Does anybody know what wire to tap into for aux. fan operation on a 1721 vintage spf ? I think this would be a good thing to have on those slow moving cruises this summer. Thanks,
Glenn

My fan has a relay that works when the water temp. sensor reaches the right temp. and provides a ground to trip the relay and turn on the fan. I just put a switch in the line to provide that ground when I wanted the fan on. I hope that helps.

Hmmm, my car which was built about the same time as yours came with one. You don't have a fan switch on the dash?

No fan sw. on the dash. SPF wants you to use the fuel pump switch or use a aftermarket switch under the dash. As far as i know they did not come with a fan sw. from the factory... |
A dash mounted manual fan switch became standard item on chassis 1900 and above. The factory utilized what was the standard electric fuel pump cut-off switch location for the new manual fan switch. (note: an electric fuel pump was not supplied with a new chassis) The actual wiring for a electric fuel pump cut-off switch is still provided with the newer chassis from the factory - just no switch exists on the dash anymore. A dealer or a previous owner may have added your manual fan switch if your chassis number is under 1900.

Olthoff must have wired it when they set the car up. Thanks for the info.

Blas, On the wiring diagram it shows a brn-blu wire coming off the thermo sw. to the relay but on mine there is just a jumper between the two relays with a brn-blu wire. Any ideas on what color wire and location to tap into to complete a circuit to the fans? Thanks...#1721 |
What wiring diagram are you looking at?

Blas, I was looking at the diagram in the owners manuel that came with the car. It shows a brn-blu wire that runs from the radiator sw. to the relay but i'm not locating it at the fan relay other than a brn-blu jumper wire connected to the fan relays at the pull down fuse panel. Thanks |

Well I had time this weekend to trace the neg. relay trigger wire that i found on the pull down fuse tray. The confusion was that the diagram i had showed one relay operating both fans when in fact I had two relays,one for each fan that wasn't supposed to be there till car # 1900. It's all good now and ready to cruz if the weather ever clears...
|
Duel fan relays started on car #1288. All cars had single relays up to that point. At car 1040 the electrics moved to a drop down fuse panel from behind the dash.

You have a PM.

I can tell Blas will be a SPF concours judge someday. :)

My fan switch located in the radiator has malfunctioned and it triggers the fan ALL the time. At start-up the fan runs. I would like to replace that switch, does anyone know the part number. My toggle switch (for the fan) on the dash works fine.
Thanks, Ron

Hey Mel,
I think I found the part # 823 959 481 F radiator temperature fan switch made in Germany. I assume its for a German or European car. |
