raditaor fan dosent work

[undercover]

 should the positive and negative show continuity on the fan

i have tried it with a full 12v battery but it dosent spin  followed the haynes manual.

the fan is off the bike so i could try this if it is possible with the NTV650  radiator fan

I must admit, I‘ve never had to tackle this problem
before but, here’s some info on how to check the fan:

The You-Tube video you've found looks pretty useful,
if you need to refurbish the brushes.

Can you turn it by hand? Mine has been seized totally solid since I bought the bike 5 years ago. Unless you are living somewhere which regularly experiences temperatures over 25C and/or you are stationary idling a lot, I can't imagine the fan being too essential. My bike only boiled over once, when I was warming it up on a very hot day for an oil change. The thermostat was also seized partly shut at that point - now fixed.
