1198 cooling fan constantly runs even when cold?

[james81273]

anyone had any issue with the cooling fan constantly running when the battery is re-connected? The bike is stone cold (not used for 24 hours) but as soon as the battery is connected it starts straight away...and the battery is drained after a short while because of this.

weird? No fault codes either on the dash.

forget it just reconnected the battery after a nights charge and although the fan kicked into life it stopped as i was tightening the terminals. Arrhh the charm of a new bike..hmm

Hi All,

Found this post by searching t'internet!

Have got exactly the same issue after replacing my rad on my 1198!
When I connect everything back up my fans are permanently on even with ignition off!
Any ideas?!
It maybe shorting somewhere but have only disconnected the fan connectors etc!

Be worth checking the Fan relay, it may have packed up

Sorted it by connecting everything up with fan fuse removed, fired it up and let it get to 108C then put fan fuse back in (wouldn't go past 62-64C with fuse in)
Bike cooled down and fan switched off when it got back below 100C. Think it needed to complete a cooling cycle to reset the fan relay as it had gone over 100C previously when I holed the rad.

More likely the relay has dried out as they are prone to moisture and Verdi Gris.

They cost £1.99 off eBay. It is the first of the two relays on the side of the battery box. Buy 2 relays and replace both, better still buy 3 and put a spare in the tool box.
