Bluebulldog Posted April 24, 2019 Share Posted April 24, 2019 Having issues keeping the bottom wires of the plug on the back of the dashboard making contact. ( ground, dash lights,right turn signal indicator). Intermittent dash lights,and turn signal light if you lose ground whole dashboard does funny things. Any ideas.

ivanuke Posted May 13, 2019 Share Posted May 13, 2019 (edited) What year is your CH613? I have a 2001 that the dash goes crazy and beeps with the seatbelt indicator coming on. I think there is a technical service bulletin (SB-732-005) about rerouting the grounding wire to fix this issue. If that doesnt work try unplugging the connector and clean it our with electrical contact cleaner on both the connector and the gauge cluster. Just google the service bulletin number and it should come up.

Yes I was lucky enough to have a dash cluster with a date code that did not require replacing. It was an easy fix.
