TBLE-02s with Speed Passion MMM 13.5 Problem

[gizard]

One of my TBLE-02s with a Speed Passion MMM 13.5 seems to have developed a problem, I have reset the ESC and ensured it's in Brushless mode and High point setup is correct.

The problem is it does not respond to any throttle input unless you turn the wheels to to get it started while applying throttle, if you keep throttle on (at any level) it keeps going but as soon as neutral is selected it will not start again until it's given a push etc.

Hmm it seems to be the speed controller as I tried another identical SP MMM 13.5 and the same problems happened. Tried an Identical TBLE-02s and set it up in the right mode etc. and it works fine. going back to the original TBLE-02s and some times it works and then other times it needs a the wheels - or if motor out of the car spin the pinion a little while applying throttle and it starts, then if you stop and quickly select reverse it works but stay more than a split second in neural and it stops again - anyone else had this issue?

I had a somewhat similar issue, (different motor and esc) and it was suggested that I check out the radio. More info here:

It sounds like you have a sensor cable issue to me.. Have you tried another sensor cable?

If the ESC is not getting feedback from the hall sensor board in the motor, then the motor generally wont spin..

I don't think it is the sensor cable as when i tried the other esc i did not change anything else and the issue went away, like wise when i tried another motor i changed nothing else and the problem remained. I guess it could be the connection on the esc for the sensor cable on the esc side but it looks okay.

I put a full pack through another TBLE-02s with everything else the same - Motor / Sensor Cable / Radio gear etc. and it was fine - so it's something todo with the orginal TBLE-02s

Does the faulty TBLE-02s ESC still work in Brushed mode?

So most probably the plug for the sensor cable then. 

Have you tried cleaning it with some contact cleaning spray?

Also check whether it is loose or any of the pins are loose. If you´re unlucky, the problem could be under the plug itself.

Trying a brushed motor was going to be my next plan - I took it apart and could not see anything wrong  - maybe there is a dry joint ... I will report back after more tests.

Well tried a Brushed motor and it's even worse - if I help turn the motor - then apply throttle it will not turn but I can feel a slight pulse while holding the motor but that is it.....

so i think it has probably had it....
