Waring lights blink

[Anchor]

All the warning light occasionally blink (speedo gauge). They just come on for 1/2 a sec and then go out. Looks like some type of short. Anyone had this problem or have any suggestions before I start in on it?

Thank you in advance.

When were your plug wires changed, it sounds like the beginning of the "christmas tree effect" ...seasonally appriopriate anyhow

check out plug wires ..with engine running ..see if there is arcing...helps if you spray a mist of water on them before starting engine..

Could be that simple and is pretty common

The wire have not been changed. I will check for any arching.

Thanks

Common problem, as mentioned, probably due to defective coil/plug wire isolation.
