I put my Rallye Guages in a few weeks ago, and everything was working great.   Tach worked fine, probably not as sensitive as one that has been re-built -- but it worked fine.    Out for a ride today and all of a sudden the tach goes crazy -- drops to zero then back up to 2,000 then down -- jumping up and down.   No change in the motor.... ran just fine.   I stopped for gas and re-started -- all was fine.   I guess I'll have to take it all out this Fall before I lay her up for the winter and have her rebuilt -- but does anyone have any ideas what could be causing this?    I have a MOPAR electronic ignition; tach wire mounted to the (-) side of coil.

I checked the wire at the coil.    Probably need to pull the whole guage set to figure out if the ground is loose....  Haveing just installed it -- think I'll wait until Fall (it's not THAT much fun).....

No, still haven't found the Qtr Belt Moldings.   :1zhelp:
