Cooling Fan Inop...

Postby spookytooth » Thu Apr 18, 2013 7:48 pm



I've got a 79 'Wing that has been a winter project cafe racer. The engine runs good (probably needs the carbs gone through) but I started it up and let it run for about twenty minutes today. The temp gauge went to the hot side but the cooling fan never kicked on. I'm wondering just how important the cooling fan is on a bike that will never be ridden in stop and go traffic... The fan should never run when the bike is running down the road, right?

Just curious for input...

The fan should kick in about 195°
Normally a 35 mph air flow is barely enough to keeping cooled off.
Make a effort to get it working.
The fan gets it's power through a 10 amp fuse and The thermo switch completes The circuit to ground.

You should absolutely have that fan working. Turn your ignition switch on. Pull your wire from your fan thermo. switch and short it to ground. The fan should start immediately. If it doesn't, trace the problem back. If it does, replace your fan switch. Your fan should kick in when the needle is about half, to three-quarters, up your temp. gauge.

I had the same problem on my 75. I just wired a handlebar mounted switch in parallel with the fan switch and turned it on when my ankles got hot.
Good Luck with it.

I was thinking this since a replacement switch costs four times that of a new fan. The temp gauge works and seems pretty accurate so I'll just keep an eye on it and turn the fan on if it starts getting hot...

Thanks for the input.
