My engine recently stopped when the Lucas Spade teminal connecting the dizzy to the negative side of the coil just fell off. It had lost its spring grip due to many years of heat cycling. As the loose lead was not visible (it had dropped down the side of the engine) this fault must be one of the most difficult to diagnose! Test lamps and voltmeters don't work too well when its the earth that gets disconnected everything tested healthy. I am posting this message to strongly suggest that Dizzy to Coil connections should be ring terminals a bit less convenient than spades but mostly imune to failures due to heat cycling.

Some years ago I fitted a solid state regulator to my TR3A. It was a DVR 3-P made by Dynamo Regulators Ltd. It made a great improvement immediately because there were no points to clean/adjust and my ammeter never went to charge. The needle stayed central. I was very satisfied with this for many years. I did notice that if you used the headlights ,and/or the heater fan, the ammeter would show discharge. I have been OK with this for a long time but I decided to upgrade this spring. I called the company but they now only do Motor Cycle electrical parts. I was advised to upgrade from 16 amps to 22 amps and they told to contact Electro Dynamic Solutions. Before I start with someone new I need to know if my existing dynamo will work properly with a 22 amp solid state regulator. How can I tell by looking in the engine bay , oily and dark. or are all TR dynamo made to cope. I am hoping that there are members on this forum who are better at electrics than me. Thanks Richard & B
