oops, thought i was in the 60 thread.
60s dont have that ground wire on the coil/ignitor, and it has a huge effect on starting. I had intermittent starts with hangs, slow turnovers, and dim headlights. That ground cleanup, and an added wire from ignitor to ground has solved all those problems for 8 months now.
Dont know if the neg switched ground circuit is the culprit, or if it is the distruibutor pickup that doesnt trip the coil collapse, and boosts resistance in the circuit so high it doesn't leave enough for that monster starter cable.
Just saying, if starter problems, clean any coil/ignitor grounds first. If headlights dimming, try the same, and add that wire to ground to body.
Thanks for pointing out they added that on the newer Toys.
