Bis wiring to the fast idle solenoid
« on: July 21, 2018, 07:57:30 PM »
Hi all

I’ve found why the first stage of the radiator fan isn’t working - the 3 cables to the fast idle solenoid have snapped off. This must have happened years ago before I bought it as the fuse is missing too. No wonder it was getting a bit warm!

I think that the black and brown should be connected to the same terminal on the solenoid, the light blue/red to the other.

Can anyone confirm that is correct.

Cheers

Thanks but I’ve got that already. I’d really like a photo of one in situ.....

I took the plunge and joined the grey and brown cables together onto one terminal of the fast idle solenoid and the blue/red to the other.
Now, for the first time since we bought it in 2000, we have functioning 2 stage cooling. Not that we got to stage 2 in today’s 20 mile test, but we know we have previously albeit only briefly.

Can’t believe that all this time all it needed was cables connecting and a fuse installed!

I’ve even managed to turn down the idle speed - the fast idle solenoid works.

Yay, today is a good day.

I am replacing my idle solenoid. One of the terminals protruding from the solenoid broke and is stuck inside one of the connectors. The fan is still working, but presumably just using one speed.

Yes. Without the fast idle solenoid connected you'll only get second stage cooling that kicks in at over 100°c water temperature. Best get a new solenoid.
