At least that's all my feable mind can recall at this time.

From many on this board who have actually messed around with the SI board, the SI batteries have nothing to do with these gauges. Typically, when you're having these problems, the SI is acting up, too, but that's partly coincidental. It appears that what happens is the batteries leak over other board traces and damage them. You could replace the batteries and not fix the problem. You can also remove the SI board entirely and still have the gauges work--all of them. Thus, you probably do have a trace problem back there that needs to be repaired, but you could totally remove the SI if you don't feel like messing with it.
