When switched on it bleeps an error 7 code. I can find nothing technical online about it at all. It's a Rio 4 (sold under several other names, the only other one I can remember being Mercury) with a 'pg drives technology' "s drive" OR "s-drive" controller - for which no search hits.
Clues: the bleeping has been intermittent. Operating the motor disengage switch often sorted it, but no longer does. The electric friction brake has been operating inconsistently.
Checks: testing the connectors that plug into the controller /i consistently get a 50 ohm load that can only be the friction brake, so that looks ok. I can't tell how the motor disengage switch is wired up. The back end should come apart for access to motor, brake & disengage switch but it seems to be seized, making access there a mare. I've noticed that it will work once every large number of times.
I don't understand the controller at all, other than it's obviously an H bridge driver. I looked for cracked joints to the termminals, no problem found there.
Where can I go from here? I'd check the disengage switch next if I could get to it, but I can't.

as a speed control fault. When I dismantled the control panel, the loom
connector fell off the board connector, it hadn't been clipped in
properly and had gradually worked loose. Perhaps the speed control
connections were the first to go open circuit or perhaps Code 7 was the
first thing the error code software picked up on.

Early this summer I repaired an AC inverter module for a solar array for an old customer (and he asked nicely). The inverter is an $800 dollar item but when I contacted the manufacturer for a schematic, the engineer told me it was "proprietary". I told him AC inverters are not a unique product and all the ICs in the inverter were off the shelf sourced, but it fell on deaf ears. Fortunately, this one was stone dead and using the suggested circuits from the IC data sheets found on line, I was able to find the problem in a DC-DC circuit.
I would be very surprised if the scooter manufacturer offered anything but a rebate or exchange program.

Maybe that's it, the throttle isn't zeroing right either. I'll go look at that later on. Thanks.

charges too much. The man who does anything that involves the
replacement of any parts seems to have access to anything that the
local dealer stocks but charges much less.

power can't be applied if the 'throttle' is already open . Forklift
trucks ran all sorts of tests like that (using relay logic in the older
models) before they would close the main contactor.

Pleased to hear that was helpful The user manual for the "TGA Eclipse"

has a list of fault codes and is available online, so it might be
similar enough to your model to be worth downloading.
