Yesterday had a bad journey as one of the wires in the battery came loose and I lost power twice. Got home, soldered it back on, and tried to charge it. The red light wouldn't come on.
I got my multimeter out and checked both the charge and load connectors, and got a good reading. I opened the battery up again and checked all the connectors and reassembled. Plugged the charger back in and the red light did indeed come on, but the green light came back on too early. Checked battery voltage again and it was about 39v. I thought the charge connector might be dodgy, as I could hear the charger clicking on and off as the connector was inserted/removed.
I tried connecting the charger first, then plugging it into the mains. The red light came on and I watched it for about 45 minutes. The charger wasn't getting anywhere near as hot as it was usually. I then decided to measure the battery again and the charger output. Battery voltage had barely gone up, and there were basically no volts coming out of the charger, and the polarity kept switching.
The charger is a 1.8A 42V by Sans Electric Co LTD, with an XLR jack. It has done 143 charges. I've got a month's warranty left on the bike, not that it matters as I'm sure they'll find a way of not giving me a replacement. The charger is dangerous as the cover can easily be pulled apart.
I'm really pissed off as I didn't need this trouble or expense right now. I need a quick way of getting a suitable replacement, if anyone knows where to get one or has a spare please let me know. Cheers.
