If you leave the battery charger plug in the charging port the scooter will not move. If the disengagement lever is not engaged the motors will not run either.

The motor controller may be bad. If the battery charger is connected to the charge port , the scooter won't move even if the charger is not plugged into the wall.

Check the multi pin connector on tiller and where it connects under the seat between the batteries. Most common problem.

Could have a wiring issue you should look in the console make sure nothing is crossed.

The Rascal 600/300, remove the seat, lift off the cover, unplug a battery, replace the old battery with a new one, putting the cable connections on the same way, red is +, black is -. Do the same with the next battery, reconnect the anderson plugs,reinstall the cover and seat and plug in the charger with the key on watch to see the needle raises up toward the full mark, allow to charge fully, overnight is good. keep the bats charged up not allowing them to drop below half way for the first 20 charges to break in the batteries. as a rule charge the scooter after every use!

The charger puts out 24VDC@4A. Typically my charger [off a Rascal 600t] will charge at 3.5A. It seems that the industry standard is to multiply the amperage by 135% providing that your using the proper gage wire and the temperature is nominal. 3.5A x 1.35 = 4.73 or 5A. So i think a 5A fuse will do it for you

Neil wood, the Rascal 600 DOES use an on board charger. What signal is the white wire looking for to make the scooter move is the question. 28v?

Does the scooter have any power to it at all? Have you recently charged the batteries? If the scooter has been sitting unused for a while the batteries may not take a full charge and need to be replaced. If the batteries are good, check the fuses and all of the battery connections to ensure nothing has come lose. Sounds like a power issue.
Good luck!

Are you sure the batteries are charged ? Is the Battery charger charging ok ? Are the batteries connected ? take off seat and cover to check battery leads, does the key fit in the lock okay ?
