Bad Solenoid?
I have a 2007 yamaha drive 48 volt cart that I think the solenoid has gone bad. If I check the voltage across the top post I get 50 volts until I press the go peddle. Once the solenoid clicks the voltage drops to 0. When I let off the go peddle the voltage across the post rises very slowly back up. Shouldn't the voltage rise back up to 50 volts instantly across the top post? The cart will not move when the go peddle is pressed unless I press it numerous times, and when it does move it acts like the power to the motor cuts on and off jerking and running slowly. Thoughts guys?
Thanks! |

Re: Bad Solenoid?
The voltage you are reading may be through the precharge resistor. If the resistor is external you can disconnect one end and re test. Sounds like the solenoid may be working

Re: Bad Solenoid?
?The Drive does not have precharge resistor or diode on the solenoid? All "precharge" is done internally, inside the controller. Sounds like solenoid may be suspect.

Re: Bad Solenoid?
thanks guys for the replies. I think I will replace the solenoid to see if that corrects the problem.
