I’ve been quoted £950 for a new brake.
I bought an entire scooter with new batteries from a local secondhand mobility place for 250!
If you've just bought it do you have any recourse to return it or have the seller fix it? Failing that a new component from an eBay seller should be significantly less than 950..
, I have a multi meter but no idea what I’m doing
Look for a setting that is "20 V
---"
Not the V with a wavy line ~
The V with a dotted line and solid line
Connect the black wire to com, connect the red wire to the connector that isn't marked with 10A (or some other number followed by an A)
If your meter has a HOLD button ensure it isn't clicked down
Put the red and blank prongs onto the terminals of one battery, it doesn't really matter which. The meter should read approx +13v or -13v (the minus depends on which way round you have the wires) if the battery is charged. If it's 11v or smaller (closer to 0) the battery needs charging.
You can use the meter on other connectors around the system to check if a voltage is being sent to them, like "is the pair of wires that goes to the electronic brake receiving a voltage", but caution: you should switch the meter to 200V
--- mode if testing other parts of the system as it will likely be higher than 20 V that you're attempting to read
I think it's also quite likely your local tv repair place would be able to do a reasonable diagnostic on your scoot; they aren't a complicated system; the motor controller receives eg 24v from the batteries, takes a reading from the throttle and pulses 24v on and off to the motor in a varying ratio of on
ff to make it run at the demanded speed. There are a few switches that inhibit it, such as the brake micro switch that prevents the motor running if the brake is left on , but overall should be quite a basic system
