Yes, I've experienced this also. It affected both my gas and temp
gauges. They keep reading higher until I thought I was overheating.
Actually its happened twice. Each time replacing the "vibrator" also
referred to as the "voltage stabilizer" in both Haynes and Bentley. You
pull off your instrument panel cover, release all the light and flasher
units from the panel and then disconnect the wiring harness and the
speedo cable. You can now completely remove the instrument panel as a
unit. The stabilizer is on the back, it is a thin black square about
1/4" x 1/4: with 3 little prongs that plug into the ribbonlike circuit
board. There is a little screw which holds the unit to the board. You
have to carefully bend the prongs with needle nose pliers to fit them
in. I paid $7.25 for this unit. I don't know why I had to do it twice,
but it did work each time perfectly. The second time took only about 1
hr total. There are pictures of this in both of the above manuals. Not
hard to do at all, definitly a money saver (like probably 50-$100). The
water light should only blink for about 3 seconds when the ignition is on
(before starting).
Hope this helps.--Charles, '83.5 Westy in Santa Cruz
