Kenlowe fan wiring

macmattom · Postby **macmattom** » 05 Jun 2009 16:03

I have replaced my fan with a Kenlowe unit and was wondering if I need to wire the control unit in with a relay, or can it go directly to the battery?

Also, I'm not sure of the current these things draw, so does anybody know the rating of fuse I should use, which I will place in the +ve line from the battery to the control unit (unless any of you know differently!).

Is it worth wiring in an over-ride switch in the cockpit?

A simple wiring diagram would be really appreciated.

Cheers,

Mac

Yes,

Wire it to a relay with the temp sensor on the radiator, that is how the original fans were wired with A/C. I have an override switch on the side of my heater cover so I can turn the fans on at will.

Yes - you should wire it through a relay and a 20 amp fuse on the main feed to the relay (not the sensor cable!). I can't believe at the price they charge for these fans - they don't supply fuse/relay/wiring diagram etc with the fan ??

To be fair to Kenlowe, it came fitted to a car so they didn't actually charge me for this. However, the reason I wouldn't buy one direct is exactly that - they are very expensive!

This might sound really stupid, but does anybody out there have a wiring diagram to direct me how to wire the unit in? The car it came from didn't have a relay, just straight from the battery; that's why I thought it didn't need a relay.

Thanks for the advice already, please keep it coming.

Cheers,

Mac

Basic relay has 4 connections - it's an electrically operated power switch. Two of them operate the coil that works the internal switch - these should be connected to the sensor arrangements - or the 'by-pass' switch, and earth. The other two are the ones that switch the high current to the fan - so one to the fuse - and then from the fuse to the brown wire (battery +ve) somewhere convenient on the car - and the other to the fan, which will of course need to be earthed. If you get a relay - it should come with details of what the various connections are for.
Sorry - I'm useless at drawing diagrams - but I'm sure someone will be along soon who has that skill!
Here's a very useful guide I found ! http://www.r1200gs.info/howto/relay.html

I have just fitted one myself and finally got it working a treat. I will scan the diagram if you want and send it to you.
I put a 30 amp fuse in mine to be on the safe side and I am yet to fit the manual override switch, but I think it will be worth it

I have not had chance to copy my instructions, but have found this on the net. It is the same as mine, but with the exception of the manual override switch. Hope this helps:

Phil, thanks very much for the link. I now just have to find a diagram for wiring the fan in through a relay - I have found one on the net that says terminal 85 goes to earth but the one I have bought has a wiring diagram on the back which shows terminal 86 going to earth!!! Confused, I am.

Cheers again,

Mac

Hey Mac, hope this helps a little. It's how Dad wired mine.

Be aware that 'Phil' said he wired his fan directly into the radio feed! This is not wise - the ignition switch will not stand the load for long. The main power should come directly from the battery +ve (brown wire) - and only the signal wire for the relay should go through Ign - to prevent the fan running when the Ign is OFF!

Where on this post does it say that???!!!

Hi Andy, no malice intended. If I had known the owner I would have given credit where it's due. I just new Dad used this to wire mine and thought it would help Mac.

All the best

Phil - to quote from your thread about wiring up your fan - " Finally got around to finishing all the wires today to my new fan and got it working all good. In the end I have tapped into the ignition wire that feeds the radio and feeding the cable through the bulkhead with the main wires (loom)". 
Despite advice to use a relay, brown wire feed, fuse etc - you decided the radio feed was the one to use ! It is likely to fry the ignition switch - which was never designed for those loads. I gave up offering advice in your thread because you seemed to just ignore anything that was said - despite it being offered with best intentions.
