Handicaplift working without ignition

[cloud7]

Looking for a wiring schematic for a 2007 blue bird vision with a catepillar c7 engine: I would like to find out how to operate the handicapp lift without using the main batteries through the ignition: Also having problems with instrument panel gauges and lighting not working

Are you planning on using separate batteries to run the lift? If so, find the positive(+) cable and negative (-) cables coming from the lift and cut and shorten them to where ever you place the new batteries. How will you charge the new batteries?

hi,
exatly this i did. i wil let him run with the home batterys.
ther are leaving just 3 kable 1 positiv 1 negativ and 1 to the switc on the door. but i still just works with ignition!!!!!!!!!!

[magnakansas]

so one big cable to negative, one big cable to positive..... there has to be some sort of control that you have to press to go up and to go down..... or other motions..... the big cables from the batteries go to an electric motor? that operates the lift? or goes to a hydraulic pump? The hand controller is _ I bet - enabled by power from the ignition. That wire, I bet a smallish one, is fed power from the ignition switch, now must be moved to the positive side of the battery like the big batterycable was moved. so the system works some thing like this -- a bit of a guess you know -- power comes from the ignition switch to the hand control, depending what is activated on the hand control, the power from the ignition is sent to a post on a relay, and that relay then connnect the big cable to the battery for up or down. along with various switches used for limits, and safeties throughout the system.

do you know how to find that little wire?

hi wiliam thanks for your answer. can you tel me exact how i can find the wire
christian
ps where i found the fuse for the instrument panel?

I would ask at your local handicap vehicle modification place,.. on my lift the tech was able to disable all interlocks in about 5 minutes,.. they would know what wire where it is and how to bypass it. there are a lot of things they can be disconnected if it is no longer a commercial vehicle( he asked me if the bus I have was a private vehicle and when I said yes he proceeded to yank interlock wires)

thanks but the bus is not on the road at the moment.i am in the middle of the conversion. and midwest busses who is closed to me is not realy helpful because they just have thomas busses.i am still sticking with this proplem.

[pbeggs]

the person you want to contact is the lift tech (what brand lift?) they are the ones who know the lift wiring and be able to tell you how to rewire it so it works all the time this is more of a lift issue than a bus issue the lift people would know the specifics of that brand lift wires no matter what vehicle it is installed in.

[magnakansas]

no, with out being able to see and test lines, I can not. I might be able to help you find it. Are you able disassemble the hand control yourself? do you know how to use a multi meter?

find a private transportation company that has a few lifts. They will have a mechanic that will be able to fix your problem. Take cash, cold beer, or a bottle of whiskey along with. Make nice with him, sounds like you will need him down the road.

When I removed my lift (to sell it) from the bus I had a positive and negative cable. that was all. I hooked it up to a spare battery to show the buyer that it worked. It was a ricon.

My lift works with no key in the bus, always on, have you tried it with the bus off?

hi guy´s,
thank´s for your posts. it s nice to hear ouer lift´s work without ignition.
but mine just work !!!!!!! when it s on. ther are 3 cables who leave 1 positiv 1 negativ and on to the switc on the door. always when i enter in the bus i take a wood bar with a screw for to start the ignition.
i cant walk i m in the wheel chair and i can´t drive to somwehre because i still seaching for a incurence. if sombady nows a solution that wod be great !!!!!!!!!

[pbeggs]

what model lift? we need more information to research the wiring of the lift to help you bypass the problem you have

[pbeggs]

step one in trying to troubleshoot this problem.

do you have a voltmeter? or even a 12 volt light with 2 wires (marker light from a car or something similar?) if you do, test the positive and negative cables at the lift to see if they have power with the key off,.. (one wire to each cable)


let me know what you find and ill walk you through this(roll actually I'm in a chair also)

hi sorry for my late answerr,
