Club Car DS 1998 does not run
We have a Club Car DS 1998 with v-glide potentiometer that stopped running. The solenoid is not clicking unless jumped to the negative of 6th battery. However, when it clicks it still does not run. We verified the following and it all checked:
battery voltage at 48v on/off switch anti arc limit switch solenoid f/r limit switches Is this pointing towards the controller? Could it be v-glide system? |

Re: Club Car DS 1998 does not run
Your OBC has failed it appears and is not supplying the Negative for solenoid operation.
What is the throttle signal coming into the controller? |

Which cable are you referring to? And what voltage / ohms we should expect? Please be aware that we do not get any solenoid activation unless we jump to the main battery negative. And even though we get solenoid click the car will not run. |

Re: Club Car DS 1998 does not run
If you are jumping the solenoid over to the Main Pack Negative (MPN) to get activation, then there would be an issue with your OBC. On a Series cart, the OBC supplied the Negative to the field coil of the solenoid to complete the 48v circuit.

With the FNR switch in forward, key switch off.... Un-plug the small green wire and small yellow wire from the controller. These are the throttle input wires. Insert the leads of your DVM into the terminal ends of these wires. Set your meter to 20k Ohms. Pedal up there should be ~5000 ohms and dropping as you go down. At full throttle you should see 0 ohms.

The only other part that seemed off was the v-glide which when disconnecting 2 & 3 on the controller unit gave a 5.88 kohm reading and went all the way to 0 as we depressed the pedal all the way down. The reading would gradually go to 0 with pedal being depressed. Does this make sense? |

Re: Club Car DS 1998 does not run
First, you need to verify the solenoid is truly passing current, and just not clicking. Then once you verify that and you have already verified throttle signal, you can measure what the controller is putting out to the motor between the M- on the controller and the B-. The voltage should be about 48vdc (or pack voltage) when the pedal is pushed just enough to engage the solenoid and then decreasing to 0vdc when the pedal is pushed all the way to the floor.

Re: Club Car DS 1998 does not run
Lets double check that solenoid. Take your DVM and place it on the 2 large posts. You should read around ~.5vdc to ~1.5vdc with no solenoid actuation. Now, with the jumper between the MPN post and the small post with the Yellow wire on it, and key On, in Forward and Go Pedal depressed, you should hear the solenoid click loudly and the voltage on your meter should go to 0vdc. If it does not, we have a problem with the solenoid internal bridge and your controller will not run the cart as it has no power.
If you are getting current through the solenoid and there is nothing coming out the controller, then you have 2 problems. A bad (or failing) OBC and a bad controller. |
