SI board?

[AndersLS]

Hello Forum...is it easy enough to change this board? My rev-o-meter and
and fuel-consumption meter are acting up!! is it just the batteries that need changing?

Rev counter failure is one of the possible syptoms of dud SI batteries, but there are other reasons as well. Do a forum search.
SI batteries are reasonably easy to change, if you're not completely freaked by circuit boards. Again, covered many times before, so do a search.
