82 250 dl tach dies when lights are on
wondering if anyone has run into this before i pull the cluster
the tach will die when lights are on, then i found its just parking lights, then i found its actually the instrument cluster lights
if u dim them all the way down tach works, as u undim the cluster the tach goes down then all the way to 0 and becomes non functional
prob low voltage on the shared bus in the cluster but figured i wud ask before i open it up and start testing it all
thanks
its a 240 not 250, 244
