    battery leakage while machine off

    UPdate, problem resolved; Turns out it was the control panel run button contact . as a summary started out thinking the battery was being drained, then a weak ground, or alternator. all that ruled out and still it would not activate the panel when run was pushed so that it would start. But...

    battery leakage while machine off

    yes, that was checked earlier on, also, I ruled out the battery leaking down, as that was the thought since it took a small boost to allow run panel to light up , so that it would start. but the issue is not the battery, its something that is taking a little extra power to allow the panel in...

    battery leakage while machine off

    I agree with possibility, of course this machine does not have a key start. Just the run button. so does power go to run panel in cab first ( top right) ? and then to ecm or other panel in cab ( top left) anyone know the sequence of how the power communiates with the ecm, and the 2...

    battery leakage while machine off

    good video, glad my lift assists work, he sure struggled. when i put the ecm back in ill recheck some of the connectors, we have not seen any moisture in any we have checked, and i do keep the machine in the dry. but again , when cold then warm moist air happens it does cause condensation.

    battery leakage while machine off

    yes, have looked at every ground on machine, recleaned battery connections, and taken apart the frame to cab connection which looked perfect. taken the ecm off and connections look great, and sent ecm to isoscell and they have said it checks good.

    battery leakage while machine off

    ive ruled out the battery , put a new one in and it did not cure the problem. the old battery had a bad cell, so it was discharging and since the new battery did not correct the problem after sitting a few days, i assumed it was being discharged also. that was wrong assumption for me...

    battery leakage while machine off

    just as a follow up, finally got a independent mobile mechanic out, he could not find any issues with grounds anywhere. He called a contact who is a bobcat mechanic at dealer, neither one had ever seen a situation like this. still will not light the panel up so it can start without a small...

    battery leakage while machine off

    update, I'm waiting on a independent mobile mechanic to come help diagnose , I've taken the cover off to access the ecm , in lower left of machine, and I can see a hair line crack where board meets the outside edge of module. this ecm was put in mid 2019, ( by error, it was actually an...

    battery leakage while machine off

    def had 2 diff issues, but i think the battery drain was incorrect, I had the issue but replaced the battery, after it checked bad. but it was still not light us the control key pad , so I assumed it was draining the new battery. and it would work when a charger was applied. But, the new...

    can anyone tell me the age of the control board by the numbers ?

    battery leakage while machine off

    yes, I've cleaned and checked all the above. the multimeter shows its getting same volts at cab panel as starter. 12.8 and that's using the blk wire as ground , so its grounded to that point. it makes sense its a ground, just not sure where. or control board.

    battery leakage while machine off

    done that, but its still possible somewhere im sure. use a meter, its showing 12.8 volts at panel, using black wire at ground, so I believe its good to this point. ive called in reinforcements ( a real mechanic) before i buy a control panel.

    battery leakage while machine off

    UPDATE; I've decided that battery drain may not be an issue with the new battery, I assumed it was because I would have to hook a charger to battery to light up the run panel so it would start. previous battery would leak down, but it did show a weak cell. 1- I've checked all fuses with...
