I have the EDIS4 setup. The RPM in my dash is not working properly. At idle sometime i have a reading and sometiime not. If i rev the engine, the RPM jump sometime but usually drop to 0. My RPM is plug to the coil using the diode bridge at the end of the EDIS4 page. If i use a test light grounded, and touch the tachometer wire, the light illuminate and the RPM start to work properly.
What's wrong?????? Bad ground???? Defective EDIS4 module???
Thanks!!!!!
