Recently disconnected battery because my jeep wouldn't start, and after getting everything squared away and back in working order my RPMS on the tachometer have seemed to have flipped underneath the little rest for the pin. So my pin which usually measures my RPMS is stuck underneath the little resting area therefore not allowing me to see the RPM readings. How can I fix this? I noticed one time before that my gauges do a little dance when the jeep won't start.
