Hi lenneig i dont makers name but ihave found a model No. MSHP4028M P4 POWERCHAIR. i charged the batterys last nite and have red and green on the chager but the control panel still reads low battery and no responce from the joy stick. the reset botton is ok where do i go from here.

Will ok lets look at the wiring for the batteries. Does each battery have a cable with a red and black lug that attaches to the battery and the other end has a connector that plugs into a connector going to the power module or controller? If it does then you should have red to positive and black to negative on each battery then plug the connectors into either one of the connectors going to the power mod. Now if you have only one connector from the batteries to the power mod. Then the cable from the connector should be attached to the red on one battery and the black on the second battery and there will be another cable to jumper between the two batteries attaching the red and black posts together. In other words you are connecting the batteries in series to provide 24 volts to the chair. If you have access to a digital voltmeter you can set it to 200 volts dc and plug the leads into the two outter plugs on the charger port located under the front of the joystick. With out the charger plugged in you will be reading the current battery voltage and after a full charge you should read 25-27 volts. If you are not getting that then either the charger is not working correctly or you have a bad battery or batteries. Will you can e-mail me @ [email protected] if you need more help good luck
