I recently checked my cutout (repro, but not an electronic one) for gap, clean points etc. No probs. Yesterday, after a longish trip involving a lot of stop-starting, I lost charge to the battery. today (i) I checked ammeter and generator: no problems (ii) I checked cutout by putting a current through it as per Paul Moeller's book, using a battery and also a 6v charger. The points chattered rapidly like an electric bell hammer but would not close. I wondered if the magnet was not pulling strongly enough so I held the points closed momentarily. Chattering continued. Finally, I replaced the cutout and all is now back to normal. But the faulty cutout was pretty new. Does anyone know what causes this behaviour?
