1986 CC 36v conversion to 48v
I have a 1986 CC 36v with the 5 solenoid and coil configuration.
I've heard about a 48v conversion by adding 2 more 6v batteriesthat will allow me to still use my 36V charger. I understand that 2- 6v batteries can be added after the solenoid for increased torque and extended range. I understand this conversion may be a little ....Um... controversial, or even somewhat unsafe. I am not concerned with any potential damage to components as I plan to do controller and motor upgrades as I can afford to. Is this what they call the Nate shunt? I only know Nate by reputation and would really value his input on this topic. I wish I had the resources to do all of the necessary upgrades in a proper manner. But right now I must try for the biggest bang for my buck. My first mistake was doing a little research and hearing so many differing opinions. As they say, a little knowledge is a dangerous thing. My first upgrade is to replace all of the cables with 2/0 cables. Will my solenoids and coils play nice with this mod? When I do upgrade the controller what is the most cost effective method? Keep in mind my goal is increased torque and extended range. Speed is only a secondary concern. Deep sand, heavy loads, and the occasional steep grade will be my biggest concerns. I realize I am probably opening a can of worms here, but feel free to chime in and get me started down the right path. I look forward to learning from those that are more learned in cart lore than I. I am a Sr. Aerospace Technician, working as an elecrtical tech., but I am learning quickly that my vintage club car is a totally different beast than my vintage space shuttle. I do mostly 28 v dc signal voltage work and cart theory is totally foreign to me. Thanks for your help. Here's a pic of my old buggy resurection so far: |

Re: 1986 CC 36v conversion to 48v
Without getting to technical....you can basically add 2 more batteries in series with the other 6 and your good to go. You do of coarse run the risk of burning up solenoids. Some will run forever on 48 volts....some will melt within a day or so. You will have to charge those extra batteries somehow.
If it were me....I would do a controller swap first....but thats me. Controllers just seem to run alot better and are more efficiant. 2/0 cable is a little over kill or your application but it will work. Best bang for the buck will be a 48 volt upgrade. |

Re: 1986 CC 36v conversion to 48v
could you provide a simple little drawing? Which batteries do add the new ones to?

Re: 1986 CC 36v conversion to 48v
Gornoman has a great post on how to do this and how to re-wire to use your 36v charger and a 12v charger instead of blowing a wad of cash on 48v charger

I drew these up in CAD real quick....The first one is wired like factory 86 cart wiring. The second one is for 48 volts.

Re: 1986 CC 36v conversion to 48v
I was thinking of using 2 connectors like the ones used to connect the charger, then just disconnect them to charge 36v then a seperate 12v charger, no need to loosen up cables then.You think that would work?

I like the trolling motor connectors because they are weather proof and made to carry heavy DC voltage. The wires are actually heavier than the 12v charger wires. |

Re: 1986 CC 36v conversion to 48v
I'm not understanding what you guys are saying - you're going to have two seperate charge systems hardwired into the pack? I would think you will need a disconnect between 36v and the additional 12v in order to charge from both ends or something like that?

Re: 1986 CC 36v conversion to 48v
That's the way I understand it.
You move the positive lead coming from your 36V charger port from the #1 batt. (+) lead to the #3 batt. (+) lead. The 36v charger port (-) lead goes to the #6 batt. (-) lead. This isolates the #1 and #2 batt. from the charge circuit. Then you hook up the 12v charger (+) lead to the #1 batt. (+) term. and the 12v (-) charger lead to the #2 (-) lead. I may be wrong as I often am. If this is the case, someone please correct me before I mess up. |

Re: 1986 CC 36v conversion to 48v
Okay, well, the disconnect part was what I wasn't catching. I found a 48v charger in the locals and just added two batteries. Real simple. Whole thing cost like $300. Used charger, 48v solenoid, 2 used batteries, 2 cables. Boom.
