so my cab collision sensor os going off. I replaced all the sensors and its still going off. I called modern machinery in washington because we do not have a komatsu dealer in alaska anymore and service guy said they had had exact issue with another pc28 and they had installed a resistor in line to fool the computer. Issue is i dont know where to put it so i need a service manual to figure out the wiring to do so. Called komatsu parts and the service manual is no longer available... anybody got one or can point me in the direction of one?
