gauge flashing - 2003-04 Mach 1 Registry Owners Club

I know that on start up the Mach gauges will "flash" peg to peg. However, mine don't do it on every start up. I don't think it hurts anything I am just curious as to why this might occur. Anyone have any idea?

sounds like you have a weak battery. it wont "flash" with a good charge.

It may not be a dead battery if for some reason you have been disconnecting your battery???? It will do it the first start even with a good battery after it has been disconnected for awhile.

If you have good connections and haven't been disconnecting --- your battery is about to die on you. Good luck.
