Coil Mounting

One thing I'm puzzled by, and other restorers of Square Fours if the AOMCC forum is anything to go by, is where the coil is mounted.

There's no definitive answer here at the moment, but this post is here to record what I have observed over the last couple of years research.

The most telling pictures are from bikes that have been dragged from barns, unrestored. Unfortunately none of the pictures clearly show the coil mounting on early bikes, only hinting at where the coil is. This post is also worth a look, as is this one.

Here we go.

  1. Perhaps there are supposed to be two mounting locations on the bike, one behind the battery for when the mudguard isn't in place and one on the mud guard for when it is in place. If you notice on the last image of the 1951 it does not have a mudguard. I'd think the people at the Ariel plant knew some individuals would remove the mud guards or they would get damaged and so they planned on more than one mounting location.
