In my case, it probably is better to get lead acid for now. I already have a stock battery sleeve that takes two cheapo 12v lead acid batteries to make a 24v battery, and getting those two 12v SLA batteries only costs around $50. A Lithium battery would cost around hundreds of dollars. I know...

I really appreciate you guys, you've been super helpful! Unfortunately I haven't had time to do more work on my bike since I've been busy with my job, but I'll get back to tinkering with it in the next few days and report back from there. Edit: oh yeah, I forgot to mention: I've started using...

And what about the lights and the horn? If the motor problem is a thing with the FET's, could it effect those too? Is there any way I could easily verify or test the daughter boards inside? Theres's 3 inside, and when I visually inspected them I didn't see any charring, fluids, or other grime...

My bike doesn't have a literal keyed switch, it just has a power nob with an on and off position. I could open the housing if needed, but I'm assuming it's good since the light in the light control housing powers up yellow, the throttle is getting 6v like you said it should, and the amperage...

Okay, I got to testing the throttle, which was a bit of a PITA because I had to take apart the throttle assembly to more easily get at the contacts. Testing revealed it is getting about 6v on the red lead, and turning it brings the brown lead smoothly from 0-6v. So I think the pot is good! I'm...

Thank you so much for the detailed instructions! I really appreciate you taking the time. I just got off work, so I'm going through as many of the steps as I can before I have to go to sleep. I started by testing the motor temp sensor, and I think it's good, or at least It passed a continuity...

I've already tested the motor and horn directly via my bench top variable power supply. It's definitely something with the controller (I think???) Right now I've got my bike upside down in my kitchen, so tested the motor by disconnecting the quick connects to the motor in the junction box and...

Thinking through it today, and I was wondering what the odds are that the temp sensor is broken or something? I doubt it'd explain the horn or lights, but it might explain the motor? I honestly just don't know if the behavior of the click sound (relay?) inside the controller is normal. It...

Here's a pic. My bf is helping me by holding the throttle all the way turned with it on, and holding the negative probe in place while I hold the positive probe and operate the camera. As you can see it's drawing some power, but none can be measured where the motor needs it. Edit: forgot to...

Okay, so I'm pretty sure I've got everything hooked up right, but its still not working. I think the controller might just be dead :c I have another 24v controller, but it's not stock so I'd loose the horn, lights, and anything else the stock one runs. I have all the connectors in the right...

You're an absolute lifesaver, I completely missed that key part about the grounding, and I must've read over it over a dozen times out of confusion. I had no idea you could do that, with the grounding of the FETs on the negative side and all that. I like to think I'm at least somewhat competent...

I know there's no internal place to connect the termnials, because I only opened the controller after taking all the way out of the bike, so I know it doesn't need some internal connection to the motor. That being said, I did open it, so I know for sure there's no terminals inside it. I don't...

https://www.imgur.com/a/CjadQZ2 Here are pics of the bike. They show the terminal block for the battery, the motor wires, and the controller in a poplulated and unpopulated state. Edit: I should also clarify that I have jumpers on the handbreak ones for now, because While I do have new hand...

I'll post some pics in a second, but I tried my best to explain everything. I think I'll likely need some help from someone who's familiar with these spesific models of bike, as the issue is figuring out how the motor connects to the controller; something which is unfortunately ommitted from the...

As the title says, I'm trying to fix up my trusty old EV Global 24v ebike. It's an old bike, but it's still good! It got a bit roughed up in my move from Utah to Oregon, but I think it's all good. I used a bench top power supply to test the horn, and the motor, and both are working good. I...
