hi, i need you tell me what controller type is fitted to that scooter before i can be more precise with fault info ,, the controller is a black, or blue or silver box located under the rear cover of the scooter ,, the wires lead to this unit...
The box is held together with a number of screws. Turn the battery box upside down and you should be able to see the location of these screws. Simply unscrew them and the box will open.
The Madrid scooter is a Shoprider scooter. The controller can be repaired by calling 800-798-0325 (Monster Scooter Parts). If you open the controller there are 2 fuses inside which are replaceable and may be the cause of the problem. I have attached a link to the service manual available for download. Refer to Page 14-15 for specific controller info. http://www.centralmobility.co.uk/includes/pdfs/scooters/Scooter%20Service%20Manual%20Live%20Document.pdf
* Circuit breaker on main control box is tripped * Fuse blown (check fuse in main control box assembly). * Incorrect polarity at battery terminals * Dead batteries. * Charging cable is still connected to charging receptacle * One of the cable connections at the main control box is loose. * Control connection cable disconnected * Broken key switch * Throttle stuck fully open * Throttle control potentiometer broken. * Speed potentiometer broken * Battery voltage too low. * Faulty charging cable. * Charger not working. * Charging circuitry in main control box assembly not working
If these check OK, the problem is likely to in the control connection cable or upper control box Verify that the upper control box is getting 24V. (Blue wire on red connector.)
* If the upper control box is not getting 24V, replace control connection cable
* If the upper control box is getting 24V, check key switch operation and verify wiring in the upper control box. Trace voltage from keyswitch on to find where the problem occurs. (Replace upper control box if necessary.)
* Charge batteries with a 12V charger or replace if necessary.
* Ohm test the charging cable - replace if necessary.
* Test scooter with a different charger, if new charger works, replace charger.
* Check wiring in main control box assembly - replace in line relay if necessary * If batteries, charger, and all wiring is good, replace controller PCB. (Note the model number for the PCB, for example 1208-2330.)
Sounds like the motor polarity has been reversed. Have the motor wires been disconnected recently. If so they MAY have been refitted the wrong way round but this would be difficult as the plug that connects them should only fit together in one way so shouldnt be able to fit together the wrong way. Could also be main control box. I have seen this happen in the past! You need to see a dealer with a diagnostics machine. They should be able to correct the problem. Hope this helps...
