k my tech dont work just my bat and gas gauge. tryed swappen my gauge with another one, same thing. guy before my did a swap and i am guessing messed up some place and i got no clue were to start with this one. any ideas?
also i have one of those after market RPM gauges how do i hook it up for the time being?

 

Check that the tach wire from the distributor is still connected. If it is, check for a broken wire.

 

Exactly what Kev said....

 

ya i checked today and its hooked up fine wire looks good. i think to fix my gauge problem is gunna be really hard. thinking about just hooking up all after market. anyone got anymore ideas on what to look for in order to get my gauges working? the Ks on the speedo dont even work, cant keep track of oil changes
