Good to know that you solved it.

[FIXED]
The solution was simple. I checked the voltage stability and it was good, so I rewired with a better quality piece of cable and soldered the connectors on the ends and heat shrinked them.
This was the solution. I think the original wire I used was either not connected well enough, was too low a quality or was getting interference.
So if anyone else gets this problem, make sure your wires are good quality and have soldered on connectors.

Original Smiths tach would behave irregularly if the connections on the coil were not perfect. Try cleaning the connectors and maybe squeeze them together some.

I have the same tach. It would behave itself for a couple of minutes, then the needle would jump all over the place. After checking and rechecking my wiring and the dip switches, I finally gave up and took the car in the an auto electronics specialist. He charged me 100 bucks to tell me my tach was broken. I returned the tach under warranty and got another one that did the same thing.
A guy at Cars & Coffee said all I needed was a tach filter [LINK]. It seems that the newer Smiths Tachs (and many others) are real fussy about the signal they receive from the coil. I installed one of these tach filters and all was well. You're welcome.

I just replaced the condensor, points, wires, arm, cap, leads, coil.
I doubt it that as the car is running super nice.

Just purchase the RVC1006 smiths 8k taco.
Wired it in as per instructions - Red/Black to - on Coil
Car starts up fine, revs up to 3000k then drops like a stone to 0 then picks back up again.
It I build the revs slowly it does the same thing.
Its a negative ground, points, 1962 A Series with an MG 1098 engine.
I have the DipSwitches on the back set to 2 PPR
On On Off Off Off Off Off On
As per instructions.
Here is a link to the instructions :

Any advice?
Thanks
