Power wheelchair, scooters troubleshooting?


Hello all,
I've searched but have found nothing posted about repairing powered scooters that are popping up everywhere.
Yesterday I repaired one (we have two in family)
It had just completely stopped working. After checking that the twin twelve volt batteries were good I just started cleaning all the wiring connections. I found a soldered wire disconnected inside the "dash" - reattached it & the scooter is working again! (yippee)
The second unit (newer & required for very disabled person) is really acting up now.
It "beeps" but won't move.
Both batteries are new and good.
It'll sometimes work after turning on & off several times.
Very inconvenient. The rider (my brother) is unable to walk or even crawl so very dependent on this as his only way to move around the house so I really need to fix.
Any ideas where / what component to look at first?

Sorry so long - thanks for any pointers! (I'm not an electronics guy but willing to learn)

Relay needs replaced. By turning it on and off you are getting an intermittent contact.

Thanks Polecat,
The scooter is a half hour away so I can't look right now...
Can I use a multimeter to confirm a bad relay?
Any idea which / where relay will be located - identifiers?
Much appreciated -

some relays are testable, you may be able to make a by pass wire, but be careful

It can be tested with a multimeter but you have to be careful not to apply a voltage to the ohm meter if you go that route and if you do the volt meter routine you need to be careful not to fry out something with the probe.

I would begin by checking out the key switch. One of the wires from it will go to the relay coil. Then you have to figure out which leads to check from there.

If you're unsure, visual inspection is best but the repair should be by a qualified person. The only thing worse than being dependent on a chair that doesn't work consistently, is being IN a chair that catches fire because of improper fixes.

What make and model? Maybe a schematic can found at the manufacturer's web site. The fact that it beeps indicates that the key switch is energizing at least part of it. Isolating the actual fault would require being able to identify all the components and wires from the battery to the drive motor(s).

Hey, g'morning & thanks for the input.

Didn't have a chance to stop by yesterday & it doesn't look like I'll make it there today either.
While I'm not a "qualified" scooter repair person, I'm pretty handy...
Agreed that starting w/ a visual inspection first. Just hard to take away his only way to get around w/o a back-up handy.
I'll be careful not to fry anything and report back after digging into it a bit in next 24 - 48 hours.
At that time I'll post more make / model specifics.

Keep on fixing things, y'all!
