Hi All,
Although I have used solid state devices to address some component issues (i.e. trafficator Relay rebuilt with relays), I must contend that, for the most part, I have experienced Steve's statement of having better luck with Original Healey devices. I am still running the same Lucas fuel pump that I installed in the 1970s and should have retained my original (given to a friend and still in use today). However, I did install a TSV diode on my pump that sets a limit on transient voltage generated by its coil and gates all exceeding voltage to ground. This provides control of power passing across the points and eliminates point burn. However, since the voltage limit chosen is sufficient to burn of winter-storage developed oxidation, the points will last indefinitely without maintenance.
Again, I am not against the incorporation of modern technology but not without understanding its vulnerabilities where possible.
