TomoHawk Posted September 5, 2004 Share #1 Posted September 5, 2004 The last time I drove my 280Z, the tacho worked, but last week I was cleaning the intake, then covered the car for a few days of rain and now the tacho quit working! I thought maybe I broke a connection or something. Does the sensor wire go from the coil to the tacho, thought the firewall by the battery? I was trying to trace the wire, but it's not easy with the covering. :hurt: BTW, where's the ballast resistor on a 78 280Z (F.I.)?thx Link to comment https://www.classiczcars.com/topic/13130-tacho-suddebly-quit/ Share on other sites More sharing options...
Zedrally Posted September 5, 2004 Share #2 Posted September 5, 2004 If you ever find out what the problem was, let us know as I have the same problem in the 77. My guess has been a dry joint or similar in the tach itself as a broken wire to the tacho would dis-able the ignition circuit.I've lived without a tach for 3 years now, so I can wait a little longer...MOM Link to comment https://www.classiczcars.com/topic/13130-tacho-suddebly-quit/#findComment-93955 Share on other sites More sharing options...
TomoHawk Posted September 6, 2004 Author Share #3 Posted September 6, 2004 I was going to agree with you straight away, but then I remembered that on the 78, there is a sensor on the speedo, not the tacho, that goes into the computer.But I think your idea is a good one; worth looking into.thx Link to comment https://www.classiczcars.com/topic/13130-tacho-suddebly-quit/#findComment-93958 Share on other sites More sharing options...
