check the ground first and foremost.
if all the signal and ground wires are not corroded or broken, then contact North Hollywood speedometer and clock. they'll do a rebuild for about 200 bucks, with new glass and chrome bezel, and a reconditioned needle. sjd

Check the points
This started happening to mine. The problem was a that the points had been gradually moving closer together and sparking(maybe because the cam on the distributor didn't have any grease and had been wearing the points). I found out when finally the car stopped when the points stopped opening. I realised the problem and set the point gap roughly and we got going again, with a steady RPM reading!
Your points could be too close and have been sparking or the condenser might be on its way out. Try checking the points gap / filing the points flat / changing the condensor or all of the above. Hope this helps. |

You are right! My points were closing gradually and when I reset them all was fine. I'm not sure why but the points seem to gradually close often. Its almost as if the screw that holds them cannot be tightened enough. I have ordered an Ignitor from Pertronix in hopes of eliminating future problems.
thanks again. |

Wow! I actually got one right! I think it was the plastic bit that runs on the cam wearing down that made my points close up - I've put more grease on now.
Doesn't the elimination of future problems take the fun out of it! You can always look good in front of the wife if there's a problem with the points and you fix it en route! |
