The dash lights will never be bright enough to see in the day time, even on a cloudy day. T'ain't like these new-fangled LED back-lit ottermobiles....

Speedo is still messed up internally, probably the little spring or the needle pivots; either has to come apart or be replaced. I had one do that and just replaced it. At least you know the speed cable and core are good; you ought to lube the cable core someday soon; moly cam lube is my favorite, but white lithium grease will do.

For the blinkers, do the easy thing and get a new blinker can (blinker relay) first; it shoudl be 2 prong. That would kill both front and rear blinkers. Let me ask an odd but related question: do the back up lights work (aassming you have hooked up the 3 prong connector on the side of the auto trannie or the 2 prong connector on the side if a manual trannie)? Also, does the heater blower work? I ask since the power for the blinkers, the backup lights, radio, and the heater blower all feed from the same fuse in that year.
Do you have a voltmeter or can you borrow one? That will really help.

No, the back up lights don't work. I for whatever reason, wanted to get rid of the seat belt interlock ( the new hemi really cleans up the engine area of wires, If you can get down to only what you need ) After messing with the interlock, and with winter quickly approaching, the need to get this engine running became priority. I decided the neutral safety switch ( back up light ) circuit need a bit of studying, and to be rewired correctly in the future. But first I had to have a running mule. Grounding the starter relay, I managed to get the engine running, and began tuning. As we all know, once the engine is running, it's just too hard to fight the temptation to drive, and so these issues were discovered. so this is where I am now.
Please tell me the neutral safety circuit can cause this trouble, because that whole fiasco all slipped mind. I guess that part needs a rewire similar to the Dusters before the interlock became mandatory.
Oh, by the way. ( and I'm not trying to say that anybody is wrong,,, please, The dash in my 1969 Barracuda lights up pretty good day, or night. I must've got lucky on that.
Please share additional info, thanks a lot.
