My Pro connect just has gone dead

[Norwichman2]

The battery still has most of its charge. It just stopped working mid way through a ride. There is no display. Pushing the button on the battery all the led flash quiet quickly. Remove the battery from the bike and the normal battery measurement is displayed on the led's (all but one lit)

Any ideas what is wrong?

Battery fuse ?

Make sure that the battery connector is connecting properly and isn't dirty.

It not the furze as I get a good 27.2 volts between the + and the Negative terminals. The battery + terminal & + bike post are not in good condition. Have replaced the bike terminals with a new one & closed the gap in the battery + terminal. Still the same problem.

If the display goes off, the problem is somewhere between the battery and the display. Looking at the state of those terminals, it wouldn't surprise me if some of the other connectors are dirty or corroded, so you need to follow the wires all the way from the battery to the LCD via the motor connectors.

If you follow the wires from the battery connector to the motor (have to take the crank and side-panel off the motor), you can check at the next connector whether the voltage is coming through the main battery connector. Put your meter on there while you wiggle the battery to see if it has a sound connection.

The centre connector of the battery is the feed to the LCD.

Corrosion on the blade in the section pic might be a pointer.
If it has affected the wire joint on the other side then wire may have broken off ?
Initially you could try lightly removing the corrosion on all terminals and add some grease to aid some protection other wise suspect wire damage as the cause.

Sorry but I have not been well. Thanks for all the replays

Battery was bought in Mar 2016 so not very old. Checked the wires to the motor and controller and they look ok. The fuse holder in the battery is distorted and bend (clearly got hot) and hove order a new one from ebay.

Rang 50 cycles but got little help. They do not repair or open batteries and so there are no spare parts.

My Battery started with flashing LEDs and a loss of power while on the bike. Then it failed altogether. I took it to 50Cycles shop who could do nothing. The flashing LEDs are error codes, normally showing a battery fault when under load. I finally got 50Cycles to sell me a discounted battery to replace my failed battery.
