Sounds like you are on the right track with your problem solving. Unfortunately you cannot determine an electronic fault by visual inspection of the components. You can see cuts, nicks, broken wires and burnt components, but this only works sometimes.
I look at the current fault code with a hand held programmer (HHP). With a HHP you can read the fault log and check out all the stored codes to get an overall idea of the history of chair problems. The 7 flash code is definitely a remote fault. You can also get this fault with a bad connecting cable between the joystick (remote) and the controller (in the base). Check this connecting cable for breaks, cuts, loose pins or connections and check the connections at both ends. You can do continuity and component checks of the remote with a digital voltmeter, but this is out of the realm of most end users.
I am assuming you have MK5 or MK6 electronics in this discussion.
The easiest test is to swap out the joystick with a known good one that either a tech has brought to your home or you have brought the joystick in to a service center for testing. The better test is with a HHP that will give you the current problem and stored information of past problems.
Weak batteries or loose battery connections can also give a myriad of electronic faults. For this reason I always check the batteries and battery connections first.
The joystick can be rebuilt, but I recommend replacement as a more cost effective solution. I always replace the joystick to controller cable too. Labor charge for this work is under 1 hour.
I can provide further information if needed. Hope this helps.

SOURCE: Can't charge Pronto M91.
Hi Bob. Unfortunately in most cases this means that the batteries have gone so flat that they cannot be “revived”. The best thing to do is take the batteries to a local battery dealer and have them checked. You may need to replace them. Another possibility is that because the batteries are so flat, the charging circuit hit a wobbly trying to resuscitate them and popped a fuse button. A simple reset may help. Happy scooting.

Richard The seat is probably rusted on the seat post It will take alot of turning and pulling upward at the same time to get it off. Try spraying a penetrant on the post just below the seat to see if that will help with the turning and pulling just keep at it. It can be a tedious task and frustrating Hope this helps
