Had mechanic checking pressures and other things. He put his pressures gauges on and watch pressures. Tried to go incalibration mode on monitor and it would not let him. Went into rpm mode and could watch rpm go up and down. i visited with dealer today. Understand that there is 4 wires. 1 positive and 1 negative and 2 wires twisted that are the data cables believe gray. Am going to start tracing wires and cleaning grounds tomorrow They are thinking it is monitor. Problem is if they open it then it is mine even if it does not fix problem is there a place that can test the monitor? All buttons work for designated items. Thinking maybe when pushing mystery non label button and whatever corresponding button for prv calibration something may be wrong inside. Like I said was going to start testing tomorrow. How do you go into prv calibration mode for this machine so after testing I would know if I have accomplished anything. Thanks
Here is a video for how to get into the service mode in the monitor panel. Below that is a little explanation of the menu and how to work things. Computer Controller Lights Yellow Monitor signal out, data problems Red Controller bad Green All OK. Data Mode Push alarm cancel button and power mode until throttle indicator number shifts. Use power mode to cycle through the Data modes. The indicator lights on the left side of the panel will flash indicating the current mode. Power shift Engine Speed Engine coolant temperature Hydraulic oil temperature Analog/Digital conversion Real time Error codes (Each code will be displayed in order) Digital output (Use work button to set each of 21 points) Output Control Display Code To stop Data Mode Push alarm cancel till dial setting changes Error Codes Push service button and power mode button until Mode 1 indicator comes on.

John c Thanks for info by your info I have red lights which means bad monitor
Any updates ? Are there lights on controller or the ones at the top of display
Top of display. Went to Cat shop for few other problems. Cheaper for them to pickup than mechanic to come out. Got call and said after some testing put in new display problem solved.
