    TMZ-34 Outriggers inop

    My machine doesn’t have the fully retract sensor swiches either. Just the switches on the feet that close when the feet are fully down with weight on them. The connector pin layout is labeled if you look close. 1-12 on row one, 13-24 on row two and 25-35 0n row three. I may be off a digit on...

    TMZ-34 Outriggers inop

    You could short pins 10 and 22 together on connector P3 to bypass all the boom switches and their wiring. Those switches are all in series and must all be closed to indicate the booms are stowed. I know you said you tested the individual switches but you can quickly bypass that whole circuit by...

    TMZ-34 Outriggers inop

    The wiring for all four outrigger switches and solenoid coils runs back to one big plug that connects to the CPU board. It’s labeled P3 on the CPU board. The pin numbers are shown on the electric schematic in the service manual. I would test the switches and coil resistance from there to rule...

    TMZ-34 Outriggers inop

    It’s a head scratcher. I’m no expert but I do own the same machine. Did you check the coils at the solenoid or from the ground control board? If you test right from the ground control board it would prove out the connector and the wiring to the coils as well as the coils themselves. Did the...

    TMZ-34 Outriggers inop

    It sounds like the outrigger switches and their wiring is OK. The control board knows they are all down. I’m not sure even if the system didn’t know they were down why that would prevent them from being raised. I wish Genie had provided schematics for the blue boards. (They do have schematics...

    TMZ-34 Outriggers inop

    I’m just wondering if the control board is satisfied that the booms are stowed. Something to check very carefully are the big connectors that bring all the wiring to the back of the ground control box. I recall threads years ago on this machine about individual pins in a connector not fully...

    TMZ-34 Outriggers inop

    Hmm, did you make any headway on this? Sounds like you’ve tried the obvious stuff. There used to be issues with the membrane buttons. The machine would detect a button press if there was a bad membrane and the machine would go stupid. Did you try unplugging the platform control’s from the ground...

    TMZ-34/19 upgrade kit troubleshooting.

    I have a 2002 TMZ-34/19 and I also bought the upgrade kit. I haven’t finished installing it yet. Still reassembling mechanicals after painting and new pins/bushings. Did you get your issue resolved?

    You’re very welcome. Glad you got it resolved and have a working machine now. Happy holidays!

    Genie TMZ 34-19 Problems

    So do the outriggers lift and level the machine now? Regarding bleeding, usually running the cylinders full stroke all the way in out several times will purge the air. There are bleeders on each cylinder but usually not needed. Each cylinder has a check valve for safety, when a cylinder is...

    Genie TMZ 34-19 Problems

    Depending on the model of your control system (there were three different versions) in addition to the auto level button there would be a separate push button for each outrigger so that you can operate each one independently. I’d have to look at the schematic but I think that gets you around the...

    Genie TMZ 34-19 Problems

    When the outriggers touch the ground do you hear the motor and pump continue to run or do they stop? If the pump continues to run then it’s likely a hydraulic issue. Not enough flow and pressure to lift the machine. Check the hydraulic fluid level. Probably a good idea to change the hydraulic...

    Genie TMZ 34-19 Problems

    Carefully check all the limit switches on the booms. The outriggers will not deploy unless the machine is satisfied everything is in the “stowed” position. Also of course check the battery wiring and make sure everything is clean and tight.

    Help getting 34/19 working

    Does your machine have the little digital display on the ground control panel? It’s a three or four digit display that will show status and error codes. Some of the earlier ones didn’t have them but if yours does that could be helpful troubleshooting. Switches are a common problem on these...

    Genie 34/19 towable manlift, Low battery issue with good batteries

    GCIRON in Florida sells Genie parts online. Gciron.com. If the blue boards are no longer available you may have to go for the control system upgrade $$$ unless you can find known-good used boards. ?? Personally I’m skeptical about having them repaired by a third party. Unless they have full...

    Genie 34/19 towable manlift, Low battery issue with good batteries

    Try unplugging the platform control from the ground control box just to eliminate that as a factor. I notice error code 0003 mentions outrigger switches in addition to other faults. Have you checked those carefully? They are a common problem on that lift. Move the foot at the end of each...

    Genie 34/19 towable manlift, Low battery issue with good batteries

    OK, so confirmed you have hydraulic outriggers as opposed to the manual screw type ones. When you try to deploy the outriggers downward do they reach the ground or do you get the low voltage condition before they even touch the ground? They aren’t doing much work until they contact the ground...

    Genie 34/19 towable manlift, Low battery issue with good batteries

    Also carefully inspect all the battery cables, connections, the heavy wiring around the motor controller, the wiring on the system fuse near the controller (1500 Amps), etc. Any corrosion or loose connection will create a high resistance point that will cause a voltage drop. Often the cables...

    Genie 34/19 towable manlift, Low battery issue with good batteries

    Along the lines of what Delmer said, monitor the voltage during that few seconds when the machine is operating correctly. It is possible the motor/motor controller/pump is drawing a lot of current. That may be dropping the voltage below the controller’s acceptable threshold. Blue boards or green?

    Genie TMZ 34/19 electrical

    I have a pdf I downloaded from Genie that is “Parts and service manual supplement”, part # 104980 Rev A, November 2005. That has schematics for a relay system. I don’t know if it’s the same as yours but it would be worth a look.
