Re: Am I expecting too much?
For those following along the continuing saga...
I contacted Alltrax today. After swapping the green wire for blue wire, back to the green wire, changing settings in the controller the tech suggested that the throttle sensor is bad. Although it checks good with a meter, it may be failing at 48V. So I have a new throttle sensor on order. We'll see. But I'm learning so much. |

Re: Am I expecting too much?
Received the new sensor, installed and same results. Another phone call (or two, or three, or...) it is now working as advertised. We ended up changing the wiring to attach the white wire to J4, blue wire to J5, and green wire to B-. It seems this is the fix for the "reversed" throttle sense. I don't know why it did not work with the old sensor.
SO at this point I at least have a functioning cart!! |

Re: Am I expecting too much?
In conclusion - what the heck was this all about
Can you sum up the problem and the fix? Here is that throttle curve you asked about.... your toque curve may be different - that's okay. |

Re: Am I expecting too much?
Ok here's the condensed version:
I got a used cart. Took it all apart. Put it all back together. Determined the AXE controller was bad. (underwhelming performance) Bought a SR48500 controller. New controller refused to work correctly when wired like published wiring diagram. Contacted Alltrax. Troubleshot with Alltrax assistance. Replaced throttle sensor at the suggestion of Alltrax. New sensor didn't fix problem until wires swapped. (Using blue and white instead of green and white) Now cart runs 20 mph. Clear as mud? I'm still not convinced the old sensor was bad, as we had tried wire swap with old sensor. I dunno. I just reread the whole thread. Yep guess I can be a bit winded. Just tryin' to sound like I know what I'm doin'... lol |

I wired per the diagram and only would have movement when i let off the peddle. So i took out the voltmeter and laptop (watched the throttle input on the software) to realize the blue wire should wire to the controller and the green wire should wire to "B-". After seeing your post today i went and looked at alltrax website and they have updated the schematic to reflect these changes within the last 72 hrs. |

Re: Am I expecting too much?
Thanks for the input. I wonder when we will see this in the manuals !?
