    2000 JLG 450A "no forward only reverse"

    I was able to fix this today with the help of some telephone support from a real jlg expert. The solution came after ruling out a bad drive solenoid. On my lift the solenoid has 4 wires going into it 2 for fwd and 2 for rev. Since reverse worked i was able to switch the wires and confirm that...

    2005 genie s80 basket control problems

    after reading your posts a couple more times, I do think checking your main ground cable in the lower box is a good idea. Once again I am not sure about the version of your lifts manual, but there is a Brown Ground wire Location "c7-3" that I would look at first. I just fixed a JLG lift that had...

    2005 genie s80 basket control problems

    I have cleaned a bunch of the wires in the basket before not a fun job. If you have wires that needed cleaning, chances are the screw terminal they are in is even worse so keep in mind when checking the lower box. Usually the lower box is in 3x better condition than the top. Do you have the...

    Genie Z 45/25 using on slopes

    well on the JLG units it is usually a 3 wire system. The only thing I have done is disconnect the sensor and on the engine side of that plug you can install a 4inch piece of jumper wire. its easy on the jlg because that side of the fitting is female so a small u shaped scrap of 14gauage wire...

    2005 genie s80 basket control problems

    Its important to make sure they are clean, but also that they are good grounds. On most of these lifts the grounds all go to 1 point int he basket and then run down to the main ground control box on 1 thicker ground wire. I have seen that wire corrode at the base box a lot in the main board. I...

    JLG 450a has no drive power

    check your grounds in the basket control box. See if you have +volts on any of the ground wires when the machine is in the run position (pull red button out but no engine running) if you see any voltage on the ground check your ground wire conenction in the lower control box. i believe they are...

    2005 genie s80 basket control problems

    Have you checked the grounds in the basket? I use a power probe because you can see if the grounds are bad. Most of my weird issues have been improper grounds.

    Genie Z 45/25 using on slopes

    it is sensitive. If that genie has a 3 wire tilt sensor you can jumper it to move the lift for travel, but it is not recommended to use the lift for any work without that sensor engaged.

    2000 JLG 450A "no forward only reverse"

    Everything works on this lift except moving forward. I have checked the EDC on the drive pump and that is working. the manual lever moves freely back and forth also. The drive control stick in the basket is only 3 months old and worked great. I checked the wires in the basket on the #10 circuit...

    2000 JLG 450A

    Butch, thank you for your help any and all help is definitely appreciated. I did see the JLG analyzers on ebay and reached out to them to see if my model qualifies. I have watched a few videos and the ability to see if the connections are OPEN or CLOSED makes the tool pay for itself very...

    2000 JLG 450A

    Hello Team, I just received a nice 450A today. I was able to unload it from the delivery truck but after an hour a few of the functions stopped working. I read through a bunch of threads and thought my issue was different enough to ask on its own thread. I will document all fixes to hopefully...
