my car is a 90 coupe with sr swap
the original cluster is working occasionally, back lights goes on and off at times, when power goes off, speed goes off. but tach and other remains normal.
so today i swaped in an exact same cluster i got off the forum. plug everything in. all works except for the tach (rpm) guage
has anyone had this problem before? how should i fix this problem?
thanks
jack
