RE: [DML] Re: Flickering Tach

["DMC Joe" <dmcjoe@xxxxxxx>]

In addition to what Harold mentioned, another cause of this condition could
be an electrical ground problem. A method to test this would be to see if
the flickering changes with voltage load. In other words is there increased
flickering as more electrical items are turned on. If this is the case than
you should check all of the system main grounds. Start with the front frame
extension ground located at the LH horn bracket, if that doesn't correct the
problem check the main frame ground at the RH trailing arm bushing bracket,
the auxiliary frame ground at the RR frame member, and the engine block
ground at the RH motor mount. There are several other ground connections
that may cause your tach flickering but the ones I named are the most
common.

Happy Holiday's,

Sounds like you just verified  the problem is not the Tach. Have you checked
fuse 1 for good contact? Also, be sure the ground wire to the ECU is in
place and making proper connection. When is the last time you did a tune-up?
A faulty or used up Dist cap and/or rotor could be at fault. Plug wires?
