gee, i stand corrected then, my post was for an older model apparently.
thanks for sorting that out Fish ;o)

William,

The parking brakes may be released for towing by connecting the two brake release
connectors located near the right front fender beside
the brake diode assembly on the wiring harness. Connecting the connectors energizes the brake coil, releasing the friction disk. The following procedures detail
the removal and installation procedures for the parking
brakes.
Now this is if you have battery power. Without voltage you would need to unbolt brake assembly. The next year they installed a red handle just under the floor plate with a cable release. You can check just incase this was installed. Good Luck

THANKS!
This is what I was hoping to adjust. I've noticed while driving it for a little while the gauge doesn't seem to move much. If I turn it off rest for a second turn it back on then I've lost a very large percent of the dash gauge battery amount.

So unrelated to the batteries, I have a question about the parking brake. Is there a way to disable the parking brake to move the truck if the batteries are completely dead? While the truck is running, I can hear the parking brake disengage via the plates at the motors. But I can't find any information about a "towing mode".

TIA!!!!

William,

The BDI adjustment is correct. Explanation of adjustment is listed below. The decrement time is used when the lift barely stops. The lift is constantly used non stop. I would not worry about that setting.

BDI Adjustment (Later Models)
(Range - First Digit 1-5)(Range - Second Digit 3-7)
This parameter setting allows for adjustment to improve the accuracy of the battery discharge indicator in the dash display.
This first digit adjusts the charged setting. Increasing the setting will increase the battery voltage or specific gravity required for the indicator to show full. If the indicator consistently reads low with fully charged batteries, decrease this setting.
The second digit adjusts the discharged setting. Increasing the setting will increase the battery voltage or specific gravity level required for the indicator to show empty. If the indicator consistently shows lift interrupt too soon, decrease this setting.
A setting of 35 is the recommended starting point for flooded batteries. A setting of 37 is the recommended starting point for maintenance-free batteries. Further adjustments may be used to fine-tune the BDI accuracy.

Okay, I was able to connect the truck to the PC using the ETACC software!!

So programming through the dash, my current settings for the battery is:

BDI adjustment = 35
BDI decrement time = 15

Here is where I am not sure what to set the values too.

Not sure if I mentioned it, but I have flooded cell batteries.

TIA!!

if you are programming the controller settings in the traction controllers both of them have to be set to the same identical settings (except for function 15 and 17).
here are the ones i show for this truck model with the SR/SP traction controller (standard settings).
-Columns- -First number is function number, second is function description, third is minimum suggested setting number for left and right controllers, fourth is factory default settings, (note: those that have different numbers ie:81/121), are a range that can be set on both controllers because remember, both have to be set identical unless it specifies differently),fifth is max settings.

NOTE: Left and right controller functions must be programmed to identical values, except for Function 15 and
Function 17.

There are 3 ways you can program these:
1-use the Yale Software and plug in to the DB9 connector behind the display
2-use the GE Handset and plug straight into the controller
3-use GE Sentry on a laptop w/correct cable and usb adapter and plug straight into the controller. (left is primary, right is secondary/slave).
Primary first, then secondary.
If you do it in the wrong order the settings will not save and revert back to previous ones.
ALWAYS recheck your settings after completing to insure they take, and are saved into controller memory.
When completing programming, shut off machine, press horn button to drain power from system, then power back on and recheck settings.

Unfortunately I'll have to wait till Tuesday to check it out. That's the next day I go to the warehouse.

But I will post the current numbers when I get there.

Thanks again!!

William,

Run the lift until it reaches 80% discharged, take a specific gravity reading. Charge the battery until fully charged and take another reading. Battery AMP hour 600 set to 17, 700 to 18, 800 to 19 and so on. This is for new batteries. With the readings you get you can raise or lower as needed to extend run time. You can also turn on the extended shift function which lets the lift operate at a economy mode without wearing down the battery. Be careful not to make big changes as it can drain the battery. What are the numbers now? There are two listings, one for early and late models. Thanks.

WOW, thanks! Little older than I was told. LOL

I was able to navigate the menus, and most of it was straightforward. My issue is when it comes to the BDI setting, I am unsure what the numbers indicate. Or which direction they need to go (up or down)

End goal is to get a little more run time. Someone else mentioned on FA to change the setting to get a little more out of it. But was not clear on what to change it to. I cannot afford $5-8K for a newer battery set. I only paid $800 for the lift. It does run "ok" just want to make it a little better.

THANKS FOR ALL YOUR HELP!!!

William,

After looking up your lift, the year is 2007. The tool required to connect with a computer is ETACC. You would use the same cable. You should be able to complete the battery adjustments through the display. I am attaching a list of steps that you may have already done.
The technician can scroll through the menu using the
up [1] or down [2] arrows and select the desired function
by pressing the [4] button. Each menu selection has a
list of submenu functions. The submenus are viewed
and items selected by scrolling through the menu in the
same manner as described above.
To exit a selected function and return to the previous
function, press the [3] button. Pressing the [3] button
multiple times will return the technician to the operator's
driving mode. Try this and let me know. Thanks.

Thanks for the reply!

-Yes it mounts in the dash.
-Yes it has the 3 pin triangle connector under the dash.
-Maybe the year is not correct. Just went by what the guy told me.

SN: F807N05205E

So I went ahead and bought a CANBUS to USB device from Ebay, it came with the triangle connector. Loaded the drivers, set up the connection in the app on the PC. Ran a test with the app that came with the unit. Sent some radon data, while the unit was NOT connected to anything. The LED lights came on so I assume it "works".

I got my hands on a Yale PC tool 4.88. When I try and connect the lift to the PC it will not connect. My CANBUS unit is listed in the drop-down for Vendor and Device. But no matter what Unit Code I select it will not connect.

So I found out the 207 is "lift disabled". I wanted the CANBUS to access the battery setting and see the password for the in-dash programming. Searched the web high and low to get the OEM default pass for the dash. Turns out it is 55555. So I turned off the 207 in the settings.

But now, I still do not comprehend the Battery setting. And I cannot find ANY info on it anywhere. And I still have no connection via CANBUS.

Please let me know if you have any advice for me on this!

William,

From what I can see your lift does not have CANBUS. They used an interface module to communicate between controllers. The dash you received, it mounts in the dash, correct? I believe the model after yours had CANBUS installed with a connection under the dash. The connector was rectangle with three wires, yellow, green and black. Serial number would help. Thanks.
