Hey Folks
I have a Greenworks 40v Garden Cart that is just turned 2 yrs old and the electronics have failed.
The electronics started failing after 1 year and gradually got worse until now - 2 years in the motor is unresponsive. It started operating intermittently, then worse and worse... and finally stopped completely. Its has button to 'engage' (like a timer and motor power won't engage unless this is pressed) and a Forward/Reverse and a Throttle.
I'm trying to repair it but I'm a newbie to this. Here's what the electronics look like:
The motor is 36v300w....
The controller (silver box) is:
and then there's a small circuit board with a couple of mosfets inbetween the battery and the rest of the stuff....
I ordered a new throttle and it didn't fix things.
Next - I think I've found a controller (with reverse function) - and ordered that.....
=========================================
QUESTIONS....
but what the heck is that small printed circuit board? If the new controller + new throttle doesn't make it work... Can I bypass it/remove it? Is it a BMS for regenerative braking (the power light glows when pushing the unit with no throttle)????
Any info/thoughts/speculation about anything trying to repair this would be appreciated. Why did this fail incrementally.... seems like electronics would be more of an all or nothing!!!
