I have an Invacare Panther MX4 and the new batteries are draining very fast (I can go about 5km). The only thing I have not yet checked is the transaxle. Yesterday we did a current draw test while loaded and unloaded. While driving the current fluctuated in what appeared a normal way. While unloaded (the rear wheels lifted off the ground) the current draw was between 3 and 4 amps.
Is this a normal amount unloaded? I can find no documentation on this.
I surmise that a high draw unloaded would mean a mechanical restriction somewhere. As there are no external oil or grease points on the drive train it must be inside.
Any insight about this would be appreciated. I don’t want to start taking the transaxle apart and find out that it won’t help.
