I think I will have to replace my ignition switch to see if I can get more than 9.4 volts at the + coil while cranking (key in start). Other posts indicate the switch could be the problem. I have already replaced the coil, resistor and ECU. Battery is at about 12.4 volts. I'm sure the resistor is hooked up right because in "run" I get about the correct 7.4 volts at + coil. Do I need to replace the lock cylinder at the same time or is it possible to use the old cylinder? If I can use the old cylinder, is there some trick to matching it with the new switch? Also, did 68 RRs have the switch light? I don't remember ever seeing one, but there is a hole in the dash where it would be. Thanks for any help!
