Does anyone have any knowledge or experience with EV Global ebikes. I have the owners manual and the dealers manual (that only really deals with assembly). I'm wondering if a schematic and service manual are available.
After a long winter I'm looking to get my ebike working again and am having difficulties.
I have a 36 Volt EV Global ebike. I also have a bad 24 Volt model that I can sometimes use for parts.
I charged up the battery and went to turn it on and I didn't get any of the diagnostic beeps or charge indicator lights to come on. The green charge light on the charger was on. I put the battery back on charge for several hours and again the same thing happened. Also there was no horn or lights.
I then took the battery inside and opened the case and measured the voltage. It was 40 Volts. There was a sticker on the battery indicating that the initial voltage was 49 I believe. I figured 40 Volts was more than the rating of 36 and should at least be good enough to get the lights or horn to work.
Last year towards the end of the season I was having problems with the on switch. It was very hard to turn, in fact I often had to use pliers to turn the switch. I thought the switch was probably bad. I opened up the right hand controller from my 24 Volt model and unsoldered the switch. I noticed that this one didn't turn well either so I used some contact cleaner on it and it worked fine.
Rather that use contact cleaner with the switch still on the 36 Volt model, I replaced the switch. After I did this I noticed that at least some of the charge indicator lights lit up briefly. This was without the batter pack attached. I figured there must be a capacitor somewhere. I thought I was making progress.
I then reattached the battery pack, the charge indicators turned on briefly and I heard a slight whine. Then the whine stopped and the lights went out. My horn and lights still didn't work.
Is this some electrical problem or maybe just a bad battery. It sat all winter.
I see you have a battery workaround, but, I also see the third battery sits on a rear rack. I have a rear rack, but, in addition to paniers which I use sometimes, I also have a bag on the top of the rack that I always use. I'd like to still use this bag.
Are there any of the 36 volt batteries available from you or elsewhere. Also, are you aware of any LiFePO4 battery/charger adaptations. If I have to spend a lot of money on a battery I might rather go that route.
Thanks for any help or advice you can give. All my local ebike dealers have gone out of business and I can't contact them.
