'85 300D RPM gauge stuck at 0
The RPM gauge in my 300D never worked since I bought it, I don't know if it is just stuck or something else.
How do I go about troubleshooting it, the 1st thing to do would be checking unplugged wires etc, where are those wires located... and does it get any input from the vacuum system ?

i have among others an 84 126. my tach sometimes also reads zero. i tap the plastic in front of the tach with my nuckle. and the bugger comes to life. for what its worth.

probably the tach sending unit. do a search. Good luck, and be prepared to be disappointed, or spend lots of $$

I've never had to fool with mine so I don't know a lot of details but the '85 MY has an electronic tach and some of the electronics are in the passenger footwell. IIRC the sensor works off the crank on the front of the engine. Others here will know more.
