Hi All,
Gadwhite,
Although I contend you can not go wrong with an electronic ignition conversion, they can fail. Although I have had a Crane (now Fast) electronic ignition since the late 1990s without a fault, I carry a full points ignition as a replacement...just in case Keep in mind that when an electronic ignition fails, it just stops working and the engine shuts off and does not start. Concerning, as this is, I have never experienced it and over the years have forgotten and now carry printed directions to remind me how to refit and set the points if ever needed.
CutOff Switch
Although there is no argument with any of the reasoning to replace or eliminate the boot grounding switch, I have used mine continuously since the car was NEW (nearly 54 years). Although theft security may be one aspect of its presence, I mostly use the switch when parked in the garage to isolate the battery and connecting a battery maintainer.
I must admit that back in 1970 when the Healey was used as our only family car, the engine began to stop randomly and without warning. Spending all hours one weekend looking for the fault and finally resorting to call a friend for a ride to work, my wife past by pushing my son and commented sarcastically "Did you look in the Trunk?". While blowing off her comment and packing up and very frustrated, I happened to look behind the switch as I was preparing to turn it off and noticed the white/black wire loose. Then and there I recognized that my problem was the result of a grounded coil caused by the untethered whit/black wire able to bounce around and ground through the battery frame. Problem solved but could not admit to my wife that her sarcasm proved to provide the key to inding the answer.
Although I have had no issue since, in the 1990s, listening to others present their switch issues, I easily dismantled the switch, cleaned all parts and packed it with dielectric grease before reassembly. After cleaning and lubricating, the switch operated easily and without issue. To help keep the white/black wire connected, I applied a good amount of solder to the contact end for the screw to grab and used a locking fluid to secure the small bolt.
No problems, worries since, no thoughts of elimination,
