I was just browsing through another Ford forum where they discussed a battery problem and the radio amplifier. Is it possible gauge failure may be linked to which radio we have?
Similarly and probably remote as well ..... I was wondering if the car were to be started with the trickle charger on (I've done this a couple of times) could this result in a gauge damaging power surge?
I agree with Doc. Hopefully we are not far away from learning what SVT has discovered with the bad gauges. Kudos once again to Dave for getting us even this far!
