Despite my name, I am a newbie to this. I have an EVG 24v that isn't quite running.

The "bullet connector" wire is not connected. Is it really necessary? Is this the same thing as a discharge connector? The wire itself, the way it is connected, looks dangerous to me. It seems to be something that would short things out. What on earth is this thing anyway? What is the purpose? Is it necessary? Can I do without it? Thanks!

As in an EV Global Motors 24V EBike? with all of the body panels and battery in the middle of the frame? Would you please take a pic of what you are calling a 'bullet wire' and post that so we can help. BTW, have you checked the voltage or done a load test on your batteries? If you have the bike I think you do, those are SLA batteries and after 2 years they will be very weak. Also, if you have been using the internal charger inside the battery box, that is prone to issues. Need more info and pics to help.

I just got brand new SLA batteries. The wheel turned once but it pulled the wires loose (missing the bolt that holds that part stationary) and now the wheel doesn't turn. :( So now I have to troubleshoot. I haven't checked voltage... need to go get a meter. GO --.--- beep code when turned on, horn works, headlight works.

Yes, have worked on many of these; however, it sounds like you may have pulled some wires loose. Don't have their manual close by; the beeps do have a code. Unplug the batteries, get the DMM and check the fuse. That disconnected wire is a problem since those two wires with the 'bullet connectors' go to the internal charger, but you need someone to reconnect that and check for any other shorts and wiring continuity before putting back inline with the controller. There's a pretty good sized capacitor inside the battery box inline to the controller if I remember correctly; so be cautious. With the battery box out, turn the on/off knob on and drain any residual energy out of the system which will prevent a surge through the controller when you power back up. These are early style systems that don't have the same protections for the controller from a power surge.

Thanks for the tips!

OK, so the red and black smaller wires don't hook together as I thought on Figure 2, apparently. But I don't know where they go. I'm peering inside the charger and I don't see where they go! The manuals are here: (Link Removed - No Longer Exists)
The beeps I heard mean everything is OK, but it obviously isn't, as the wheel doesn't turn. The green LED on the charger is always on. I thought that was good until you advised me that those small wires should hook to the charger. Thanks for your advice!
