    289D Drive motor speed sensor faults 2685-8

    I did. I used one of the cab flood lights I had lying around. Regular bulb, not LED. The light was same brightness on signal wires as when I connected the light straight to battery.

    289D Drive motor speed sensor faults 2685-8

    I've had 2685, 2686, 2687 and 2688 from the beginning, so all 4 speed sensors are faulted. I disconnected the inclinometer harness at the firewall so everything running down that arm is out of the system. I've got all 4 speed sensor faults and all the associated faults that come as a result of...

    289D Drive motor speed sensor faults 2685-8

    I was finally able to get back out to the shop and build a load test light using a spare cab work light I had lying around. All wiring to speed sensors light up as do the three wires to the inclinometer. Light seems just as bright through machine harness as it does connected directly to the...

    289D Drive motor speed sensor faults 2685-8

    Here is the report. Without the inclinometer connected, I have the 3700-3 active. Connecting a jumper to ground per step 5 of the troubleshooting, the active code switches to 3700-4 telling me the sensor has failed

    289D Drive motor speed sensor faults 2685-8

    I'll have to figure out how to post up the report, never ran that one before. It's the OEM manual. 268X codes all appeared at same hour. That was over 100 hrs ago. This has been a backup machine as I worked on some emissions/engine issues. Emissions faults had highest priority so I never...

    289D Drive motor speed sensor faults 2685-8

    Just went through the 3700-3 troubleshooting again. Seems as though I had a bad ground when checking things late yesterday. Went through from start to finish and it's telling me my inclinometer is faulty. As in my original post, with that fault active, could this be driving all of my speed...

    289D Drive motor speed sensor faults 2685-8

    I have a 289D, TAW05187, that has abnormal drive motor frequency faults for all 4 speed sensors (2685, 2686, 2687, 2688). It has the intermittent fault that only shows when moving the machine. I've gone through the service manual and all the wiring checks fine according to the troubleshooting...

    Cat 289D 1.5 PSI fuel relief valve

    ET is the bane of my existance right now. Wouldn't connect for what seemed like all day. Got new drivers loaded and it all fired up. It was end of the day, so figured I'd get back to it next morning. Won't connect again. That was Thursday morning and the guys blew a seal out of a case 580 trans...

    Cat 289D 1.5 PSI fuel relief valve

    The thing is, we have good flow out of the filter head. I'm just trying to find out what issues the fuel relief valve can cause. If the HPFP is getting 12 psi instead of 1.5, what symptoms will be present? I'm not even sure that I have a fuel problem. We cleaned the dpf because it was past...

    Cat 289D 1.5 PSI fuel relief valve

    Working on our 289D, TAW05187. We have several issues but I'm thinking a lot of it is caused by a fuel issue. Currently, when we start the machine, it stumbles as if it was starving for fuel and stalls out within 5-10 seconds. Transfer pump filter and the primary filters were changed as they...

    Case TR320 Crank Sensor Troubleshooting

    I have asked for the diagram from the dealer. The service writer says he is not proficient in navigating their system to find the information that I needed and said he would have tech get in touch with me. Finally did hear from the tech with the information in my original post. Going back over...

    Case TR320 Crank Sensor Troubleshooting

    Hoping you guys can give me some assistance as local dealer has been of limited help. I've got a Case TR320 with fault codes and Stop Eng light on. Codes were for crank and cam sensors. Dealer found bad cam position and crank position sensors. They replaced those and fault would not clear...
