Cat 315B monitor problem

Dieselfixer · 2021-01-13 15:03

Hey All Having a problem with a315B. The monitor will work sometimes and sometimes won't. When it quits working the green & yellow light on the computer is on but when it works only the green is on. Any ideas on where to start looking for the problem? Having to use the bypass switches to move the machine. Any help is appreciated. Hope I don't have to buy a $4000 ecm or a $1800 monitor. Thanks!

    Wiring/connector issue..? Post a Serial Number. That gets you an electrical schematic.

    Hi, If both the green & yellow lights illuminate on the controller it means a communication problem between controller & monitor. It means four things can happen 1.controller is faulty or 2.monitor is faulty or 3.controller & monitor both faulty or 4.there is a wiring problem between theese two units. But as you mentioned if your problem is a momentary one most likely the problem will be a wiring or connector issue as Sir Nige mentioned.
