Alltrax SR600 issue

arrowhead · 05-14-2018, 03:53 PM

I have a 99 EZGO limo that I recently upgraded. I converted it to 48v, new trojan 8v batteries, Admiral MOT-B1 motor, Alltrax SR600 controller, SW202 contactor, 400a solenoid, 2ga wires, etc. I had an issue a month ago where i could only get 85% throttle so Scottie told me to do the Clear Auto - Cal on the controller. that fixed the issue. Yesterday my cart quit after a couple minutes. i cut it off and on a couple times and hit the throttle a few times and finally it started going sporadically, enough to get it home. I checked all connections and everything looked good and nothing was hot or warm. i did the Clear Auto - Cal again and everything seems to work again. Any suggestions on what i can do to keep this from happening again? Is there a software update for the controller? mine says V1.1

I have the same controller and when I plug up my laptop it says V 1.1 with a build date of Oct. 30, 2017 so I am thinking that is the latest version. And as I am finishing up my 48v upgrade ąswell hope there isn't an issue. i

I would check throttle linkage & test throttle sensor.

cgtech thanks for your help,
How do you test the throttle sensor and what should i be looking for in the linkage?

First open the pedal box and check for any moisture. Use a hair dryer if any is found. Second the pedal box wires have been extended in this cart. There may be a bad connection in the extended signal wires or there may be an intermittent micro switch in the pedal box. See throttle signal testing too in the stickies.

Looking for hardware that is loose, allowing throttle range to change. In the case of a ITS throttle type, check slug adjustment. Not sure if you have ITS or 0-5k ohm throttle type.

Thanks for the help. I will check these things. I have ITS throttle I believe. Could a problem with the throttle box cause the controller to change?

I think if your throttle signal is bouncing around the auto-calc could be thrown off it's game. In which case re-calculating would correct the problem until it reoccurred.
