Default Re: Dual horns - Wiring

The points should be firmly mounted as the coil is. The armature is the inner shaft that moves inside the electromagnet.

It looks like yours are missing the nuts & locknuts that open the points. Check this cut away. It looks similar to yours but has a different projecter cone.

Here is a GM type but there are similarities with all vibrator types.
