Phil, Brice:
This was from my post awhile back.
It was specifily to fix a problem where
the high beam and signal indicators lit
continiously, and dim lights
in the auto check display. After appreciating
the symptoms on and off for about a year
I was quite familiar with what was happening.
Pretty much it had to be a floating ground
because that is the only signal which touches
all the devices in question. It was obvious that
ground was not at 0 volts, and current was flowing
backwards from the way it was supposed to go.
After I took the circuit board out and traced
the ground for the devices in question, I found
one common weak point near the corner of the
spedo. It tested OK at first (hence
the intermittant nature of the probem) but by flexing
the board a bit I could force an open at that point.
There must have been another resistive path to ground
or else the display would have been totally dark.
A bypass operation was required and fixed things
nicely.
