2001 IHC Dash Cluster Problem
Now I know why they call it a Cluster. International outfitted all their vehicles for several years with a smart analog dash cluster. If you have one, you may have experienced the thrill of dealing with it.
All idiot lights on the left and right sections of the dash work fine. Left and right harnesses.
Two issues - Center Harness
Fuel gauge reads full all the time. Sender in the tank or cluster?
When I start the engine, all gauges perform a single sweep and then stop working. On occasion it wakes up and I get readings. I've pulled the unit, pulled the circuit board, check all the soldier joints where the harness connector attaches to the board. They are clean, shine like new, and all have continuity. Me thinks the unit was pulled and rebuilt at some point. All the contacts are clean and covered with a non-conductive grease. The last owner of this bus who used it as the backup for his school fleet maintained it pretty well. Any ideas? Anyone have the pin-outs for harness so I can measure for voltages? Should I be looking upstream? Does this thing have a brain somewhere that drives it's tiny little CPU?
Thanks in advance.
