trouble diagnosing solenoid activation circuit
Cart
2001 48V DS Club Car Series Complete 600 amp upgrade from www.cartsunlimited.net 1.5 years ago Problem The cart won't move, and the solenoid doesn't click. I started the diagnosis but got stuck. Here's a picture of my solenoid and my understanding of the posts: Test 1 Voltmeter connected to posts 1 and 2 No pedal = 0V Pedal pressed = 0V This means that my solenoid activation circuit isn't working. Test 2 I did step #2 of this website voltmeter POS to solenoid post 2 voltmeter NEG to bat 6 NEG no pedal = 0V pedal = 48V This means that "positive input is correct". Test 3 I did step #3 of the website voltmeter POS to bat 1 POS voltmeter NEG to solenoid post 1 no pedal = 48V pedal = 0V I think my results are reversed from what I should get, but I'm not sure. What do I do next? Any idea what's broken? |

Re: trouble diagnosing solenoid activation circuit
Run a Jumper wire from your pack Neg and then to the small post where the Yellow wire is. Then try it. If it works, you have lost the Neg coming from the OBC.
To test you should have: Key On, Fwd selected, Go Pedal depressed. (cart jacked up for safety) |

...add a 10 fuse to a 18 gauge wire and place this wire and fuse to the vacated solenoid terminal and to a battery negative connection. At this point computer replacement is not necessary. However, if you wish to retain the “lock out” function you must replace the computer. So basically replace the test jumper I used with an 18 gauge wire with a 10 amp fuse. Only issue with this solution is that the drive system won't be locked out while charging. That doesn't bother me. Sound correct? |

Re: trouble diagnosing solenoid activation circuit
It is just that the Neg (Yellow) wire was supplied by the OBC and when charging it will not supply that. I have never fused one before as it is just the Neg between the solenoid and pack.
You need to monitor your OBC and make sure you have the 5-10 second delay when you plug in the DC receptacle and that is cuts off as it should. Usually when the OBC starts to fail, it continues that way over time..... |

Re: trouble diagnosing solenoid activation circuit
(In case Nole is taking a nap) If the OBC is bad I would bypass it and replace the charger.

Re: trouble diagnosing solenoid activation circuit
MC was describing you a way to get you going for now and the better selection for New.
Here is the OBC https://www.revolutiongolfcars.com/p...8-04-ds-series Here is the best charger (does not need an OBC) https://www.revolutiongolfcars.com/p...rger-13-18-amp The OBC is good, but 25 year old technology. The Summit II is the best smart charger on the market.... And yes, I am headed out and will not be around.... Good Luck with whatever you do..... |

Re: trouble diagnosing solenoid activation circuit
Hi Chip, thanks for contacting me.
I have the Lester Summit II suggested in that thread. It is our best charger. Our price is $305 plus the round 3 pin cord for $46.25 = $351.25 These parts are in stock ready to ship > http://www.cartsunlimited.net/lester-summit-ii.html If you are handy you can buy the charger alone for $305 and cut the old cord off the old charger and save some money. Let me know if you have any questions |
