Merit dma mobility scooter

12 volt 35Ah Gel battery. Lots of places to buy. Have you had it load tested? Isn't it holding its charge. Not lasting long enough?

Hi Robert , can you clarify what you mean by a trickle charger ?, any chance of a photo of the charger ?

using a standard gel battery charger , the charger will charge the batteries in question and once fully charged, the charger will trickle charge the batteries.. This is a standard operation and recommended by battery makers...

Are there any fault codes, flashing light. Check your user manual in the trouble shooting guide.

Have you disconnected charger from scooter as it will not move if it is still connected to scooter.

The charger will cut out when the batteries are fully charge. Look for the green led on the charger.

if the charger is a 12-14 v charger you would have to charge 1 of the batteries at the time. connecting both in parallel during charging would cause a short. and in series (the way you have them wired) would provide too low a voltage for the batteries (6-7v each)

if the charger is 24-28v charger you would connect to the wires going from the batteries to the controls/motors (not the connection between the batteries) this will provide each of the batteries 12-14v charge

hi, if the lights aren't coming on, that's a no, check the the mains lead as these are standard to those used on computers and other items found in the home.

Robin.

Things to check: Drive/Free wheeling switch, brake release lever (this activates an internal micro-switch that enable power to the drive system, battery box connectors (condition of contacts - corroded, missing, loose. etc.); main control cable (corrosion. lose or missing pins, etc). If all these are OK, could be controller or drive control potentiometers (speed, forward, backward) on the handle-bar (tiller).
Good luck!

Hello

Check the following:

* 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.)

With the battery charger lol I don't know if your scooter has the battery pack or not but if it does there should be a charger port located on the battery pack just plug the charger into the port and let it charge overnight. If it doesn't have the battery pack then there should be a port located on the tiller usually under the throttle levers Hope this helps

What type and what voltage were the old batteries removed from the scooter?
