Have a 1998 freigtliner fl70 business class with a cat 3126 engine with a six speed auto allison trans. the speedometer and tach have been check out by a calibration shop, both work and operate good. I have ran the power and ground checks with a ohms/volt meter both have good voltage and high ohms. both sensors one for the tach and one for the speedometer in the trans check out good. checked out all the grounds, cleaned all the cannon plugs,, still have intermittent operation of the tach and speedometer. does any one have a wire print for this year or have any suggestions or pont me in the right direction to fix this problem I have. thanks paul rphipockets@hotmail.com |
