I'm talking about ALL NEW components. New controller, harness, light, throttle, only old is PA.

What would explain the throttle working, but pretty much nothing else, in the current test phase (arrows off)? Are the phase wires correct, while sensor wires are not lined up in the connector with the arrows eschew? You mentioned something about alligator clips to test this, do you recommend...

Very strange and a bit discouraging. I pulled motor plug, turned throttle, no error. Using a multimeter, I determined that this is the current way the plugs are wired on extension cable (see pic). Perfect mirror image. Not sure how to do this for the motor plug, or current controller plug. I...

Yes, when plugged into itself, the arrows on the extension cable line up.

9 Pin motor cable arrived from ebike world. It fits the motor perfectly, and the new controller just like the original (arrows at about 30 degrees off). Throttle works. I can use this cable inside my new controller. Before I attempt this splice job, any tips...

I figured the old display wasn't compatible with the KT (error 30 said *maintenance*). I have changed P2 settings from 0 to 6, and in everything between. So it's not the P2 # exclusively. The LCD3 you have is the exact same thing as the LCD8H, except a better interface (according to video)...

@harryS That connector IS an extension, yes. BIG NEWS Okay, connected!!! - with arrows at about 30 degrees off, added battery, and the throttle works! Seems like RPM is higher (judging by sound) No error message, but also no MPH or PAS (currently hooked up to old PAS, haven't installed new...

Here's another shot of the 9 pin connector coming FROM the motor, obviously male. Good news on speed sensor.

If I had the right connector, I'd attempt this ASAP. I have one on the way - potentially (but could be the same thing). The only sticking point is having to disable the OLD controller to salvage the connector. I'd like to do a dry run without disabling anything. I'm still unsure about the speed...

Arrows on a connector s don't line up when it appears pins do. I was at this for a while I wonder if the 25 amp controller, which mentioned 750 watt fat bike, is slightly different, and would work.

I was going to follow @harryS recommendation to splice in the box, not on the board. I have to believe the notches do not line up, as I cannot get to 2 motor connectors to *plug in*. I cleared it up as best I could...

Just to mention, my motor cable is about 8 inches long. There is an approximate 2 foot extension cable from the motor cable to the controller. That gives me an extra connector. The big risk here is separating the connector from the cable on OLD controller and not being able to get the NEW...

No worries, this is a learning experience, and I do have a multimeter now. I can solder, usually working with 18 gauge wire and circuit boards. I am also beginning to wrap my head around the entire process, and what's needed. Working with these connectors is new, but I will master it. If I had...

I've learned a lot, and for that I'm forever grateful, but sadly still no actual upgrades - except the 52 volt battery giving me about 2 or 3 mph, (maybe up to 4 fully charged). There seems to be issue after issue due to my lack of experience and Addmotor's selection of proprietary parts /...

I was looking for a better charger on Luna Cycle and found this - Julet 3 pin to 2 pin converter. Now it's a waiting game for all cables to arrive. The only soldering I'll need to do is swap out the xt60 connector on the battery cradle...

I figured as much. I took a look at the PSA cable. Connectors match, but too cable too short on new controller. I picked up this extension cable that should work. https://www.amazon.com/gp/product/B07KK9KKSP/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 Voltimeter arriving tomorrow, and...

May be a silly question, but do the wires have to be under any load to test? Where? I would do it at the 3 wire connector. Then mark the 2 pins were going to use. Makes no difference which wire is which here. It's an on-off switch. So I can do this without anything assembled hooked up? Am I...

I agree, one job at a time, or at least getting a complete grasp on what needs to be done before I start. OK, we are going to change the ends of the OLD brake handles to match the new 3 wire harness. I took the NEW handles apart, and there is a simple button switch that slips into a housing...

I apologize for the confusion. I'm doing the best I can with everything new. And I really appreciate the time and effort. The throttle connectors are the same, which means I could use old or new throttle with new harness. The display wire would match, but i plan on changing the display. The...

When shopping around, researching ebikes, less is written about gear ratios than motor options. When I got my bike, pedaling topped out at 15 mph, not very satisfying for me. I've upgraded to a 60 tooth ring up front (while the existing 7 speed 11/28 cog remains in the rear), and can now...
