    Alltrax AXE 7245 controller

    Hi, not sure it is worth mailing. The 0-5k ohm throttle cuts out constantly. I have some family member that live in Sacramento. If no one picks it up, I will send it up with someone to Sacramento. Stay tuned.

    Alltrax AXE 7245 controller

    Hi, to access the programing port, you pop off the black plastic circular piece on the front. I also have a cable. To get the program, you need to open the manual on Alltrax's web page and click on the link.

    Alltrax AXE 7245 controller

    This controller came out of a 2012 Zero motorcycle. It would cut out regularly with 0-5k ohm throttle. I replaced it with a newer controller. Thought I would post here if anyone would be interested before I take it to an electronic waste site. It might work with a deferent throttle (0-5 volt)...

    I have a stock 2012 Zero X with what shows as a Control Area Network issue. The shop says the throttle is malfunctioning and Zero wont provide any in

    Hi, I had a similar problem with my 2012 Zero X last year. I am still having trouble finding information and parts. I purchased a new throttle, which did not solve the problem. I ended up purchasing a new controller and the bike has been working great. I hope you got your X up and running and...

    2012 Zero X with no battery

    9/18/2023 update First, I kept getting ads for this Emerson R48-3000e3 power supply so I purchased one set at 58 volts for $89 from AliExpress. I did not think it would last. It is 1/3 the size and weight of my 1500w charger. After a few weeks I am very impressed. I had to...

    2012 Zero X with no battery

    Up date: After getting a new throttle, and trying many different programing settings on the original controller, I still had the bike randomly shutting off. unplugging the battery and/or popping off the throttle connectors from the controller, then reconnecting seemed to work for a while, but...

    2012 Zero X with no battery

    Thanks Amberwolf, My battery does not sag much and the cutoff usually happens around 10 mph, either slowly accelerating or slowly decelerating. I have not been able to find much information on this form. The golfcart forms have good info on the Altrax controller. 0 to 5K ohm throttle faults seem...

    2012 Zero X with no battery

    OK, I have been having an issue with the Altrax 7245 controller cutting off power to the motor. It happens when I am just riding along, suddenly lose all power. There is no blinking codes showing on the controller, just a solid green LED. I assumed it might be a throttle issue, so, I rewired...

    2012 Zero X with no battery

    Update 11/23/2022 Got the Zero to the DMV for an inspection (Vin and Motor number check). Had to take off the bottom panel so the DMV official could view the motor number. Since then, I have about 200 miles, mostly around town with some short road trips. My longest trip is 25 miles. Top...

    2012 Zero X with no battery

    Update 11/4/2022 Final finished a battery and got out for a ride. This bike is a blast! I just did short spurts in the neighborhood but was able to hit 52 mph a few times. Here are some screen shots: So far all I have done is connect the throttle directly to the controller (with...

    2012 Zero X with no battery

    Today I loaded up the Zero with 3, 15s ebike batteries. This is about 4 KW of battery. My first run, I hit 45 mph on about 3/4 throttle. After that, I could only get the bike up to 35 mph. I figured that I had blown a fuse. I continued riding around the neighborhood for another mile at 25 mph...

    2012 Zero X with no battery

    Thanks for the encouragement Luke. I was able to get the controller, motor, and throttle to work. I do not have garage so I work at the bottom of my condo stairs and push the bike out to a carport at night. Here is my first test without the throttle bypassed...

    2012 Zero X with no battery

    Saw a street legal 2012 Zero X with no battery on Craig's List for $895 and thought it would make a good project. From what I read, the original battery was a 14s, 3 kw pack. Not sure this is correct. I hooked up one of my 15s batteries charged to 58 volts and all the 12v electronics (lights...

    Update 5/21/2021 Still riding the 1000w bike to work when I am allowed. Only 19 times this year, about 1000 miles, because we were required to work from home (zoom) most of the year.

    Automotive spot welder as battery welder?

    I purchased this automotive starter solenoid from Ebay: Have about 150 welds so far, looks like this: Here is a video: https://www.youtube.com/watch?v=jPtiwKFbtBw Works better than the cheap Ebay spot welders and if you have a 3s lipo or a good starter battery laying around, could...

    Battery update: The 15s x 8p LG MJ1 pack I made 3 years ago had to be retired due to the last 2 parallel groups having way less capacity then the rest of the pack. I was getting less than 15 miles before my controller would shut off the pack (sag to 42 volts). For safety reasons (fire), I have...

This is the 4th straight year using this 1000w hub motor which has over 28,000 miles on it. The controller is 6 years old...

    looking for high voltage shut-off for solar charge

    Hi electrical experts. I have a harbor freight tools 100w solar unit. This system consists of 4 x 12v panels hooked up in parallel. It also comes with a 12v charge controller, which I used until my lead acid could no longer hold a charge over night. Lately, I have been charging my 30ah battery...

    Finally had to drive a car to work due to rain. Wanted to keep my ebike commute streak going, however, my streak staying upright seemed more important. Used my daughter's car and filled up her tank. Since I donated my car in August, I think this is the first time I have pulled into a gas...

    1/2/2018 update: December 22nd was the last day of school and my last commute on the 1000w bike. This semester I commuted 89 days by bike and none by ICE. We had no rain so I had no excuses not to ride. I ended the fall session with more than 4,500 miles. Not really motivated to buy a car yet...
