I bought this Excavator and was told the Hydraulic Temp. Sensor was bad. I replaced it, no change. After running a short while it jumps up to High Hyd. Temp, getting alarms. also the fuel gage seemingly randomly goes to low fuel alarm and different levels, up to full, back to empty. Since I had both issues I decided to change the MCU. Nothing Changed, Problem hasn't changed. Must be a connector/wiring issue somewhere ?
