Question about RTO Mobil Line Mobility Scooter Chair Battery Charger31004

1 Answer

No output from circuit board

Replaced TR5(SCR), but it didn't come for 6 weeks. Now I don't remember how the white and the black output wires hook to the
printed circuit board.

Also, does the output need a load(the batteries), in order to show a
voltage of 24V? . (It depends on the output circuit).
If I had a schematic of the PC board, I could troubleshoot it better.

Thanks for your help,

I'm working on one of these chargers tonight. The white wire from the internal breaker is connected to terminal "PL" and the black wire to terminal "MS".

Hope this helps... Maybe you can fix my circuit board! Several fried components.

hi, the brake is controlled automatily by the controller, it stops you moving once you released the wig wag and slowed down ....

Golf Cart Wiring

James can you trace the wires back to the source? Sometimes there are 12v accessories such as a fan or radio on those that would require you to hook up the wires on the positive and negative from two connected batteries to get a 12v output. So in your video, all you would have to do is move the small black wire to the negative of one the batteries connected to the one with the yellow bungie. The red wire should be okay where it is. Trace the wires back if you can, but hopefully this helps. Good luck, sir.

Work all days yesterday, this morning went out to van, got to work and it would not move, lights come on flash but will not move

The code 6 failure code is the toggle throttle [engager] isn't in the neutral position when power is applied to the scooter. If the engager doesn't return to the neutral position as soon as you turn the key on the scooter would start to move, that woul

1. Check connections on red, white and black wires at crimps and soldered joints. (Flash Code
2. Use meter to check for:
- White & Red: 5k1 + 10%
- Red & Black: 2.5k1 (approx.)
- White & Black: 2.5k1 (approx.)
3. With meter between Red & Black, squeeze engager forward. Resistance should go from 2.5k
down to 01 smoothly.
4. With meter between White & Black, squeeze engager reverse. Resistance should go from
2.5k down to 0 1 smoothly.
5. Check voltages (with key on):
- Forward - Red- 4.5V + .1V
- Neutral - Black- 2.5V + 0.1V
- Reverse - White - .5V +.1V
If using a Test Harness - White & Red: 5k, Forward - Red & Brown: 2-5k, Reverse - White &
Brown: 2-5k.
1. Use Red & Brown squeeze engager slowly forward 25 down to 0 slowly.
2. Use White & Brown squeeze engager slowly reverse 25 down to 0 slowly. Make sure dial
speed is set to10.

I have a IZIP I200 scooter I replaced the batteries and still does not woork

Although your device isn't a mobility scooter, they share many similarities. The following info should be of help to you

If when switched on you don't get lights you are not getting any power to the tiller head, the meter should be reading voltage regardless of the condition of the control circuitry. My first scooter was a very old AMIGO, it sat in a barn for 20 yrs, this was anything but a dry environment.As a matter of fact i has to a power washer to clean the two inches of Chicken manure off it. This scooter was so old that it has an discrete component open controller board as opposed to fully potted and enclosed LSI based controllers we see on todays scooters. The engager in the tiller was oxidized, and had to be cleaned and dried out. I rinse the controller out with distilled water then put it in a preheated oven at 150 F for 24 hrs. WARNING make sure of the temperature some ovens will not go this low. The newer controllers are potted and enclosed, making them water resistant, they use LSI which are proprietary and can't be purchased or repaired. I liked older controllers because you could fix them.

What you got to do is what we call "chase the voltage" First you will need a 24v circuit tester

You may also need a VOM meter only $9

The problem is 24volts is either not getting to the tiller head or you have a broken wire in the tiller head. Start at the headlight make sure its switched on. Use the circuit tester, put the clamp to ground, use the probe to find the 24volts, The hot side is the side wired in series with the switch. The tester will light up when it has voltage. Chase the wire back through the system. When you get to a cable or anywhere you can't see the wires use the VOM meter, disconnect the scooters batteries leaving the power switch on. Set the meter to read resistance scale high scale, short the probes together, zero the meter. Put one probe at the headlight the other probe at the connector you think the wire ends up at. Normally every wire is a different combination of colors like red; with a white stripe. Most of the time a wire ends up at a connector and the color code doesn't change. So if you are not getting continuity on any of the pins on the connector you know its got to go, you've isolated the open circuit too the tiler head. Here's a test you can run! Turn headlight on, power on for scooter, disconnect scooter battery, place one probe at head light. Disconnect tiller cable. Probe each pin, one of them hast to cause the meter to deflect to zero. If if doesn't the problem is in the tiller head. When working with little wires i like to use crochet needles. You can use the meter to check cables each pin in must have a pin out. If you don't get continuity between pins the cable is bad toss it.

Hi, I have a gogo mobility scooter...when the key is pushed nothing happens, no sound, no indicator, i checked connection, batteries are charged, lever is in the right position...any idea what could b

Get a 24v circuit tester

Connect the black lead to the negative side of the battery open the tiller head and expose the key switch, use the probe end of the circuit tester to probe the two wire connections, one connection should have 24volts on it.If there is no voltage at the key switch this means you don't have power getting to the tiller head. Check the cable that connects the tiller head to the body of the scooter, that both sides are plugged in and tight. Check all breakers, fuses, check all the wires in that they hide the fuses all over the place. Unplug and replug checking for pushed pins. You can start at the battery and chase the 24volt thought the wiring. The beauty of the circuit tester is that long sharp probe. Its perfect for sliding down the side of a wire in order to reach a pin on a connector.. If 24v is present on the pin the tester will light up, So if on one side it lights up but on the other side it doesn't pull the connector apart and reconnect to re-seat the pins, look for pushed pins. Hope this helps

I needto replace the battery charger on my Rascal 600F scooter

Hi. Most chargers with only two wires, have a small bridge wire from the
black ( negative ) wire to the middle terminal of the connector. This disables the controller while the machine is charging. The charger will still work without this bridge wire, but the scooter will still operate normally.
There are a few different chargers around that have an internal relay that disables the scooter, but these chargers are normally "on-board" chargers.
Good luck. Neil.

Model# RR100 MFG Code 27046B, got 2nd had with no manual. How do I hook up the new batteries? So many terminals to choose from?

Hi.The best idea if you are not to sure, is to get help. If you want to do it your self, be careful, batteries can be dangerous if shorted out.
Each battery has a positive ( red ) terminal, and a negative ( black ) terminal.
Change one battery at a time, make sure the scooter is turned off and /or unplug the battery leads.
The red wire will go to the red terminal ( positive ) onthe battery, the black wire to the black terminal.
Each battery should have 1 black wire and 1 red wire to it.
Remember, be careful.Neil.

Phantom 3 wheel scooter back-up alarm

Easy fix; pull the floor board off by removing the 2 phillips screws. There is a round, black piezo with 2 wires connecting it; a red wire, and a black wire. Cut either of the wires, and then tape both ends of the cut wire to prevent it from grounding out on something. No more annoying noise. To hook it back up, shave the wire's insulation back and connect the wires again, but I don't know why anyone would want that installed again; I guess so someone doesn't back over a dump truck in the scooter ;).

I think the funniest thing (April Fools Day Prank) to do with that damn alarm would be to hook it up to a toilet seat lid, but in a way that the alarm only goes off when the seat is lowered, so if someone had to take a dump, they'd have to listen to the alarm...this might keep employees from taking 30 min bathroom breaks ;)
