Just removed the SI board from a recently purchased '89. The batteries I've seen in illustrations all look like typical AA batteries you'd put into your flashlight, remote control, etc. Not these...they are about half as long, made by Sanyo, with a name of 'laser' n them. The two batteries are held together with what appears to be epoxy. Also, there's a fluorescent orange sticker on the board reminding me to put a three post jumper in the lower (ON) position.
Anyone know the vintage of these boards? I don't want to replace the batteries if not needed.
Oh, the brass nut beneath the fuel gauge was missing. Could this be the cause of the gauge 'jumping' when in the 3/4 full position? Also 'jumps' if I press lightly on the plastic cluster case. Will replace, anyway.
