YDRE Troubleshoot
Yamaha YDRE left me in the road this weekend . Stopped to say hello, and when I hit the go pedal, the car just "jerked in place." It continues to simply jerk in place. 52V Pack charge. Tow/Run, On/off keys tested and good.
I have Plowman's Riot Kit with Alltrax XCT 48500. I have narrowed my issue down to a bad MZJ-400s failure, or a bad connection somewhere along the line (I think). Am I on the right track? Cart does resist being pushed and wheels turn slowly when go pedal is pressed. I hear no click from the solenoid, ever. I cant quite grab hold of how to test Solenoid. I see lots of B- B+ references, but can't relay that to my solenoid. Also, I see that some folks say I may need a resistor and/or a diode. Thank you, and please ask for more info if needed! |

Re: YDRE Troubleshoot
It's probably the solenoid. I had one of those fail same way on my YDRE. IMO they are a crap design. My failure was the little switch on the bottom that is supposed to open to disable the pull-in coil. If it doesn't open, the pull-in coil fries and then the solenoid won't properly close.

I should add that I plugged the controller in, and got the following "errors." e.g. these three items were highlighted in blue. Shutdown - Precharge Fail - Low Battery. Can you speak to any of the anode/resistor requirements for this setup? Is there a different between the $50 amazon solenoid and the $115 solenoid from somewhere like golf carts modified?

Re: YDRE Troubleshoot
The cheap solenoids I have seen on Amazon were Chinese clones. I don't know how good they are. Your errors do suggest a bad solenoid though.

Re: YDRE Troubleshoot
Update: I found, on Amazon, this solenoid which includes the diode and resistor. I will update once installed and tested.

Re: YDRE Troubleshoot
So, the new solenoid worked, but my batteries seem to be dying faster. They are also 5 years old.
