Hi all, hope all is well in Patrol world. I've done all soldering and cleaning contacts on the instrument cluster of my Patrol gq. The only instrument acting up is the speedo. When the car is switched off, the needle rest at 0 once started it jumps to 180 max and stuck there. Thumbs on dashboard sometimes fix it temporary. Going over bump also sometimes fix it. This doesn't happen always. I have added extra ground and tested it.
My question is, what would cause it to stuck at max: short with continues high voltage, spike from sudden short or not one of these. NOTE I am now trying to determine if my feed from sensor is the problem.
Last question, is the transmission sensor on gearbox close to emergency break or closer to gear level (manual).
The speedo sender is near the hand brake. Have a look at the wiring harness to the back of cluster as it sounds as if you are getting a spike from the voltage supply.
Will have a look at the harness thanks. Will also follow the wires from sensor to cluster and clean all plugs and connectors. I also thought it might be a spike pushing the needle beyond the upright position to drop on the wrong side. Cheers
Hi guys, still have the Intermittent problem, but I think I have the cause now. I took out the instrument cluster again, and noticed something loose inside. On opening it was a capacitor thing in a black plastic cover (see the 2 photos). Must have came loose with knocking the dash to make it work. I can't make out the writing and don't know where it should go. Do any of you have an idea where it comes or have a photo of the speedo pcb , as the value might be printed on the pcb. Should be a quick fix if I know what to buy, and where it should go. Cheers all.
Thank you very much Mudnut. This will help me heeps. I will Compare my pcb with the photos. I Could also get some writing on it - 4.19 mz so will look on the pcb where that is marked. I have posted to a new thread as well as this topic is of topic for the components. My apology if it seems as a double post, but it was not my intention. Just need to source the new 4.19 mZ component now. Cheers mate.
I apologize for the delay in posting a result here. I got 4mhz resonator from RS on Friday. Will put it in this weekend and will post the results. Cheers
