fishy68 and redfastback:
Great info on NSS and voltage drop. I can see green corrosion around the strands where it was stripped to go into the replacement battery post clamp. That is why I told him to take it apart and wire brush it, but there is no way to clean all of the stuff between the strands in the middle of the cable which probably goes back down into the insulated part. The voltage drop is a great way to check how bad it really is.
73 red-duster - yes, we did replace the relay.
I thought about the NSS, but it is not affecting me here. I have a 68 340-S (which could be a twin to the one in redfastback's picture - we have to pm and see if they are identical). Mine is just a basic 340-S with auto and a console (same color and stripe). It wouldn't start with the key once, so I jumped the relay. I didn't notice the shifter slipped down a little and ended up chasing the car down idling in reverse. (Thanks to a lumpy cam with a low idle - I caught it before it hit something - and hoped nobody saw me). I learned that jumping the relay bypasses the NSS the hard way. I then made a mental "note to self" to check that the shifter is in park before getting out to jump the relay. Do not try this at home, and if you must, have someone inside the car to hit the brakes and put in park before disaster strikes.
