I cannot find anything that explains what it means when the warning light on the dash blinks 9 times,  anyone else see this before?

So I bought a new Alltraxe controller and it works out of the box.  sometimes  when I start  I give a little throttle and then you can feel the power stop and the motor makes a weird gurgling sound and If I let it do it for more than 6-8 seconds the display shuts down.

When I first installed it I had this issue and after about 5 re-starts it worked fine and I test rode it up and down my street.  then took it to another street whwere I was able to hit at least 45mph.  worked good.

I go to start it today and as soon as I give a little throttle to take off it goes into that gurgling sound mode with zero power applied to the wheel.

I'll grab some video and post a youtube link here in a little while.

The battery is fully charged, maybe too much voltage ?    it seems like the ESC is going into an over current foldback mode lol.

has this happened top anyone before on a 09 with brushed motor?    I have not programmed it at all, strictly out of the box alltraxe.


edit:  video link

Well  the Alltrax is dead  :-(   time for a new one.

I have a AXE 4855  that is not powering up  ( no LED )

I get that it's a sealed/potted device.

Has anyone figured out a way to bring them back to life.  mine worked until I removed the PMG-132 motor to replace the brushes,  now it will not power up.

I know how to troubleshoot and repair ac/dc and dc/dc power supplies,    has anyone found where the fuse location would be etc ?  possibly I can use something to dig out or dissolve the potting compound around the effected area.

I just do not have the cash to get a new or used controller right now.

Thanks for the welcome 

Darn,,,   I should have made a video when I did my brushes.   it was tricky to get all 8 springs compressed properly.

I took a lot of photos,  I can probably share a Google + album     Where would be the best spot to post something like that ?

Hello Everyone ,
My Name is David,  and this is my first E-Bike.  I just recently acquired a 2009/2010 DS with 1,600 miles on it.  The problem it had was motor cables were falling off and the motor bolts were falling out..  Has a PERM PMG-132 in it.

Battery pack achieves full Green light  ( 100% charge )   I have not actually measured the voltage yet

When applying throttle it would move the motor and cause a lot of arcing etc  ( since the power cables were super loose )  also the motor made crazy clunk sounds as it slid in the adjustable motor mounts...  ok   I solved both problems and installed new brushes while I had the motor out.  Simple,  also broke in the motor brushes slowly on the bench using a 400 watt battery charger in NiMH mode and 4 amps  ( this just slowly ran the motor up and down for a while)


I re-assembled everything,  and now the throttle will not enable.   Power-on beep and self check appear to be working fine.  the display does show an "  R1  "  while it is doing the self test.  I cannot find any info on it yet.  possibly it's a clue ?.

I am new to all this,  but I am a Mechanical Engineer that also designs and builds my own Aerial drones.. I work for XP-Power designing custom AC/DC and DC/DC power conversion products, so I am knowledgeable in the realm of mechanics and electrical/power,  So I can understand the lingo that you guys are speaking  ;-).


I do not mind doing the legwork at all,  I just was not able to find a Wiring diagram or even a service manual for this bike  :-(.

after reading what I have so far  it seems there are various reasons for the throttle to be disabled.

one thing to note.  the temp sensor was hacked and twisted back on to the harness.  I did remove it and solder it back and heatshrink it nicely.   it does turn the fan on when I hit it with hot air.


the warning LED on the stand-alone bracket on the dash,  seems to blink when the kickstand is down and or when the kill switch is in the off position.   pushing the switch to the ON position and raising the kickstand causes the warning LED to stop flashing.  so it appears both switches are operational.

I am not getting ANY LED action on the Alltrax controller.  I guess at first I want to verify that the controller is actually ok.

I just find it weird that it allowed the throttle before I took it apart, maybe I missed a wire somewhere ?

I just joined this forum today, and Plan to read mostly through the Zero related posts.  it has to be a simple problem,  not like the tranny or clutch is bad lol.

Thanks for taking the time to read my long post.

I'm in Morgan hill California.

in researching I found the Alltrax AXE is programmable ! cool.   my computer does not see it as being connected.  :-(
