for 914-6. just got tach back from palo alto speedo, which repaired tach after arching coil smoked it. New coil now and car works fine. Tach works correctly up to 4,000 RPMs. Then needle falls back and flutters. Do you think the problem is with the tach or something with the car? palo alto speedo will surely look at it again, but thought i'd query this group first before the hassle of removing and mailing again.

Not sure if it applies, but I had a similar problem on my 72 4 cyl--turns out I had the black/violet and red/white wires swapped on the tach terminals.

That said, I'd call PAS before doing anything and see what they say . . . .

Hope this helps,

does the engine cut out when the tack does. i know my 67 mustang wont run with the factory tach disconected. (possibly tach. completes the curcuit on 914's too)

happens on our jeep, but its casue the tac is old, and the car has does bounce around alot (dirt trails, what can i say)

it is probably some connection on the speedo is screwing up
