Tractor loses speedo, tach, temp gauge, oil pressure guage at diffenert intervals.
Ground fuse to ECM was blown and replaced. All grounds were cleaned and are in working order.
Seems like when truck is first started it has none of the listed gauges operating but the gauges come on sometimes after about 10 minutes of operation. Computer behind dash that operates gauges tested okay. |

If you monitor the ecm with insite, and it displays the proper gauge readings, that narrows it down to the truck side. I'm not well versed on Stars, but I would guess that this a datalink driven cluster, therefore a pair of twisted wires would deliver this info from the ecm to the dash cluster, check the integrity of these circuits to eliminate the harness as the problem (do you have a wiring diagram?). |
