Discussion: Genie Scissor Lift

What i used to do all day now takes me all day to do.

Unit is a GS- serial 543XX. Has new batteries but the BDI shows only one led light lit and blinking. Batteries are fully charged. platform console is not showing error or is the ECM. Unit will travel but really slow. Platform control raises platform normally. Have checked relay, platform com cables, key switch wiring. Thinking it is possibly the ECM. Ground control works good. Any ideas? As i have talked with couple other co-workers who have not seen this before.

yep RCA
sometimes that happens
i've ran into that once in the past...
ran me around in circles for a bit before i just took the judgement call and got another controller.

good job :o)

Update and solution. After talking with several electric techs and looking over entire wiring schems, came to conclusion that the ecu was faulty. As the unit..

1 was travelling but slowly
2 had no code showing
3 was fully charged ( new batteries)
4 tilt sensor checked ok
5 pothole switches ok
6 platform switch ok
7 wiring checked ok
8 joystick checked ok
9 platform controls worked
10 ground controls ok

After pondering over all i had checked, seems the logical solution was to stab in a new ecu.
Installed new ecu unit and unit operated ok.
Seems the bdi is controlled by ecu and internal failure does not mean it will code. Live and learn i say.

The unit was doing this before the battery change. Batteries were replaced due to not holding good charge and charging quick when charged. The customer said the old batteries were boiled dry and added water but did not help.

as long as they are all connected in series to equal 24 volts that shouldn't be the issue. Besides there is a battery wiring diagram on all genie machines.

Did this error start when the new batteries were installed? Could it be they were not connected correctly?

well the BDI indicator is controlled by the circuit board inside the platform controls. The LED's in the menbrane go straight into the circuit board, that monitors power from the battery voltage in the main control circuit and displays the indicator related to the battery voltage.

Thats the reason i asked to double check the connections in the harness connectors, one may be corroded causing an irregular voltage at the platform control box.

worse case scenario is the circuit board in the control box may be bad.

Have checked the tilt sensor also. I will recheck all connections again and do a ecm swap. I am wondering where the bdi signal is generated from? The the ecm or the pcb in platform control.

no those dashes are just meaning there are no codes present... the flashing pulse led means it is powered on and communicating.
(sorry forgot some of them display the dashes)

do you have another ecm to swap out with it?
might want to try that

did you check the level sensor?
i would go back through the connectors in the harness and make sure all the pins are connecting, it sounds like you have a bad connection if the bdi comes and goes like that.

Already tried the sb disconnect several times. The ecm is displaying 2 dashes and the blinking light. This is not shown in the repair manual code list. I checked the Dip switches and another dip switch card had been installed to rule out the card. A couple times i had the bdi to show all bars but as soon as a function was operated, the bdi went back to the one flashing led. Have already checked the pot hole switches, platform raise switch. perhaps the 2 dashes displayed holds a clue?

if you are going to post the serial number put all of it there, partial numbers mean nothing.

as for the bdi problem , try what was suggested, unplug the batteries and replug them back in.
if that does not work then look on the side of the unit where the little square window is and see what the LED code is showing.
if all is normal it should be blank with just a small dot blinking.

as for the slow travel that is because of low batteries, which we can rule out since these are new, so check all the switches on the sissor assy and pothole system. Also check the level sensor and make sure it is indicating power on and pull it over out of level and see if the led's on the bottom change, there should be a power led and also a fault led that will light up when out of level.

I had a Genie BDI that would read batteries dead and was flashing even though they weren't. The BDI was connected all the time even with key off. I disconnected the batteries by pulling the SB175 connectors and that must have reset the BDI because all was good after that.

I was thinking it might be a switch in the scissors that tells the controls that it is up, as far as the speed, but then I re-read it and don't really have a clue about the BDI.
I assume you know the Genie website has the manuals, and you have checked the dip switches in the platform control box.
