A family member recently purchased a 1995 Cat 315C Excavator to do work on their hobby farm.
The machine has a monitor that has gauges for fuel level and engine temp and oil pressure as well
as a few other things it monitors. It also controls several other functions on the machine. They bought it
knowing there was a problem with the monitor. The unit does not power up when the key it turned on.
Today I took the monitor off and disassembled and inspected it and could not see what the problem was.
The voltage regulator is outputting 5V.
Any help sorting this out would be greatly appreciated!
The numbers off the ICs are:
IC1: 4K1RJ HD63BO1YOP
IC3: 9427H 74HC04AP
IC4: HD74HC74P
IC5 PA2004C 9441EH004
IC6 3773P 9428 M89GT
IC8 SN75176BP 40A59TJ
Thanks In Advance!!
