Mr Pronto wheelchair is at least 10 years old, for it was owned by my late father. The batteries were not charging, so my mother and I got new batteris and tried to change the but to no avail. The man at the battery store sold my mother batteries that have the connecting probes on the top. We attached the batteries, and we think they were inserted right, however we cannot fine the place where attach the battery cables to the chair itself. We need a diagram of the way to attach the batteries, please

Nurseboy16 goto to Invacare.com and on the homepage select wheelchairs and topend then select powerchairs then select Pronto series then select nonpowered seating scroll down until you find M91 then on the left side of the page you will see owners manual select that and look on pages 62-63 on how to connect the wirng. You should have wiring crisscrossing each battery black on neg post red on positive post on opposite batteries and the large connector will connect to the large connector going to the controller or power module hope this helps
