I have a 99 Country Coach, 98 Prevost XL, and begun to get erratic gauge readingstoday. The 24 volts would go down to 20Vfor a while and bounce around before returning to normal and doing the sameagain. The front and rear air pressuregauges would read normal and occasionally bounce to zero for a few secondsbefore returning to normal.
I checked the 24V at the battery jumper connections and thevoltage was as expected at just above 27V. So, I’m confident the problem is most likely a poor connection in thecommunications bus to the gauges. BTW, Ihave a Country Coach with a glass display. I doubt it’s the computer that drives the display given all other gaugesperform normally.
Any thoughts on which connectors to start with? Any thoughts on my logic being flawed? I’m in Minot, ND so getting commercial helpis not going to happen here. They have a Detroit Diesel shop, but it doesn’t doservice; they only sell parts.
Thanks,
Gil
