Bought one of the name brand units with the extra wire...oh about 5 years ago.
Installed it......the car ran great but I got spooked by it, because a friend of mine put one in his 69 Firebird, and it died on him over 50 miles away from home coming back from a car show.
He called, and I brought him points / capacitor and tools to a Delaware town......4 hrs later he was back on the road.
One thing you can say......the likelihood of points leaving you stranded is almost nil.
These new pointless systems for old cars just make me nervous.
Great idea....but no thanks. I'll keep my points system.
I agree about the potentials of electronic failure though the new cars I have owned from the 90's and on never had an electronic module failure anymore (now that I think of it maybe because the electronics are now mounted on cooler surfaces compared to the inside of a distributor...when they were still used) .
I still use points in my boat for the reason of reliability because a sea tow is very $$$$ overall and using a boat is seasonal in NY.
I don't use my Camaros' as often as I should and when trying to start them was a challenge. Cleaning the points worked in those situations even though it took only 10 minutes. If (big if) I do go with an electronic unit, I'll certainly have a point/capacitor set in the travel tools just in case. Then again, having a mechanical anything setup (ignition, fuel pump, clutch, etc) on an antique car is part of the overall ownership, fun and pride I guess. Sort of like having a kick start Harley vs. an electric starter today.
Well..heck...Sounds like I just talked myself into staying with points!
