Remember this only works up to the first 6v motor on a frame....1965 MY August 64 to August 65...the 12v armature will not fit that SWF motor...
That 6v motor has a different cast face and the armature is shorter.
See my post about having a 6v 65MY motor built by wiperman in USA.

I did this conversion on my swf wiper motor. It was so easy to do it was untrue.
It will be strange to not have my wipers whizzing around at warp factor 5 anymore though!

Check the wiper motor gearbox. If you didn't service that at the same time as changing the armature, you might be lucky and your problem might just be due to the grease turning to gunk inside. Mine had gone crusty. Could be jamming one of the gears. Take photos before you touch anything in there though - the gears just pull of the spindles, so you'll need something to remind you of where they go.

Also, check the teeth of those gears. They're only plastic. If the motor jammed under load it might have stripped or chipped teeth.

I've just done mine on a 65 and had to change over the centre pin. It was an easy job and now it fits and runs a treat

Had a look and all is ok in the gears, I'm blowing a fuse everytime I turn it on :( Again got it working but as some as you disingadge the wiper arms it stops working again.

Just a thought, did you run a cable from the case to earth?

am update regarding the 1965 wiper motor. As previously pointed out the new 12V armatures do not fit the one year only wiper motor.

There is another solution. Get hold of a 1968 beetle armature part number 113 955 813E. its 12V and slips right in. I must thank Don West for sourcing one for me. He also points out that the new 12v armatures have the wrong gauge wire and therefore don't spin at the correct speed and also run slightly hot!
