Put tv in 24 volt 12 volt tv lights up but won't come on

if the voltage for the tv is mains voltage then you will need an inverter to bring the power up the mains voltage for the tv
if it is 12 volts unit then check that the battery is set at 12 volts or the switch on the tv is set for 12 volts.

i'm having the same problem. checked fuses and both are good. going through the wiring harness to look for shorts. have a bad feeling the micro controller died, that is the little plastic box with metal fins on it under the seat post behind the batteries ******* to the frame. i can bypass the micro-controller and connect one 12 volt battery directly to motor and runs full speed. somehow it is wired with 2 - 12 volt batteries in series to give 24 volts and them the processor cuts back down to 12 volts to run the motor. not sure why this is engineered this way? still working the problem. what sucks so far is that the micro controller is encased in resin so it is virtually non repairable.
* Update added.
Found these wiring harness for sale online scooter stores and on ebay. I replaced mine with some intermediate level adapting the harness to my model scooter and this includes some soldering and wire splicing changing power connector heads off old harnedd to new harness to fit bike. Works great.

12+12=24

I don't think there is a in accessories. The 24 volt truck systems are Cranking and Lighting. Either way you have no risk at trying the lower 12 volt car electrical. The problem is when you reverse polarity.

Bob make sure that the wiring is connected correctly to scooter controller in other words if the cables from the batteries have a connector that plug into the harness coming from the controller make sure that connectors (if color coded) match up and that they are seated correctly. Look on the underside of your rear shroud for a wiring diagram and make sure that the new batteries are wired in that way Hope this helps

All Scooters are 2ea 12 volt batteries in series = 24 volts dc
Serial numbers for a shoprider are on the seat post or body frame, some scooters over the years have lost the sticker and you won't be able to find one.
Here is what will help you get a manual.

Good Luck

Something in the power supply is bad from over voltage, look at the mosfet transistors

at error code is 12 and it is your 12-volt supply. Measure from the inverter to the power supply for 24 volts pins 1,2 and 3. If you don't have the 24 volts disconnect the inverters from the power supply and see if the volts come up. If the 24 volts come up replace the inverters. If the 24 volts are still not there replace the power supply. The volts have to be steady and not going up and down if they are replace the power supply.
But if the 24 volts are there with the inverters connected 1M03 pin 3 for 3.2 volts. If the 3.2 volts are not there replace the small signal board. The only way to get a manual is to find it on line or call the manufacture.
