Yes Andrea, i connected it to a fully charged 12v battery. All I got was a few sparks when I connected the positive wire to the red terminal. It spins OK by hand.

I don`t know what happened there, it disappeared before I`d finished!
Put an Ohms meter across the 2 wires. If there is continuity the motor should be OK. Check for continuity between both wires and the casing in turn, if you have then you could have a short to earth which would cause the sparks. If no continuity across the 2 wires, you have an open circuit, sticking brush maybe? I presume you earthed it? It doesn`t matter which way round you connect it, it will only spin the wrong way if incorrect.

Be brave and make a good contact! They do draw quite a current, and also have a bit of gyroscopic tendency leap out and chop fingers off. Good luck! |

I rigged the fan up via a tested push-pull switch so I know I’ve got good contacts. No sparks now. The fan works intermittently. When first switched on it spun for a few seconds then stopped. Most subsequent attempts showed no response. Occasionally a slight turn. Feels like something is binding. The fan blades are free and not touching the cowling. When I disconnect and turn the fan manually it turns a few revolutions then seems to bind. Should it always spin freely when manually rotated?

Hi Norm. the fan should turn freely by hand with no resistance. try a little WD40 down the shaft and keep turning by hand,you may be lucky

Source of problem detected! I disassembled the fan and found that one of the large outer magnets has become detached. The outer rotating ring has been scraping against it and binding. Just to be absolutely sure, I reassembled without the loose magnet and the motor spins freely.
Am I right to assume that the adhesive needed to fix the magnet back in place is not something readily available, and that I will need to get a replacement fan?

Hi Norm, good work on finding the problem, could you stick it back with two pack epoxy I would think it would stick back perfectly then retest?

Think I heard that failure in a heater fan. I would use superglue. Large area to get a good fix. Make sure you de grease and glue exactly as it separated and clamp two bits together.

Thanks for the recommendation Neil.
I've not had good experience with superglue in the past Tim - maybe I've not applied it correctly. I have had success with 2-pack epoxy though. Do you not think that would be suitable?

I have had excellent results on repairs like this using one of the Henkel 'Nural' 2 pack products. There are various types of Nural and not all variants are on sale in all EU Countries but I believe B&Q seel some and also Amazon.

I remember it was on an electric window winder. It is always worth taking these things apart as a simple fix brings them back to life again. Re epoxy JB wonder weld is probably what I would ave used but still stick (pardon the pun) by super glue if the both mating surfaces match (ie no air gaps), unless of course the original glue has failed and is or has broken away. |

Great news that you've found the cause, and why not attempt a repair given you can bench test and its not sooo critial for all I'm sure we could imagine ways it could set the car on fire. --- I always used to think of superglues for when the fractured surface would refit with no gap. However stuff like this will fill a "gap" and there's all sorts of "hacks" out there to mix with fillers like baking soda and wood dust. https://www.yandles.co.uk/zap-a-gap-cyanoacrylate-super-glue/p4109https://www.starbond.com/tutorials/fill-large-gaps-in-wood-using-super-glue/--- However for that job my instinct would be epoxy... I wonder what was used originally? |

Thanks for the input chaps. I couldn't find Nural in the UK so am going to use two-pack epoxy Araldite. Will have to be a thin layer as I've got to maintain a gap between magnets and the spinning portion of the motor. Andrew Cliffe at Omicron recommended using slow setting.
I'm fitting the rear windscreen today so will carry on with door/window seals until the epoxy arrives.
