Hello,
I've a '79 TA with a 403ci. I've replaced my old speedometer by a new one which do strange things.
When i drive Under 45mph, the speedo is under the real speed. Beyond 45mph, the speedo is upper the real speed. The more I accelerate, the upper he becomes. When I drive at 70mph, it shows 80mph. the needle don't bounce but looks free, moving to right and to left when i Accelerate and decelerate fast and quickly.
And the miles counter is very fast. When I drive on 5 miles, the counter adds 30 miles...
Wires good and speedogear is the good one (regarding my wheels, the speedgear into my transmission and the ratio of rear axle).
Is my speedometer is dead ?
Is anybody has an idea about this ?
Thank you all
Chris
(sorry for my english)
