critique my plan
Hi all.
So I received a free 95 EZ GO Medalist DCS cart. I have been reading on here so much the last week my eyes and head hurt lol. Anyways I've come up with a plan for it and need the experts on here's input. Im gonna either build or buy a pre fabbed new battery tray due to the current one being rusted out. I haven't got to choosing battery's yet though until I confirm my plan. I plan on first getting a PQ bandit motor because mine is fried. I did the jump S2 to A1 and connect a 12 volt battery charger to the other posts and didn't get anything. Note: I have been told the gears/rear end may be shot too. I plan to run 48v. Am I correct in assuming that a 36v motor will run on 48v or do I specifically need a 48v motor? I then plan on Scotty B's package with an HD solenoid and DCX500 amp controller and will use 2 or 4 game wires depending on what y'all recommend. (2 game I assume). I m thinking I will do 6-8v battery's. I think I want a 6 in James lift and 22" tires. So please fire away and let me know what y'all think. |

Measure the Field windings and Armature windings with an Ohmmeter. If you've got continuity or both, Plum Quick might be able to rebuild it and you will have a torque monster. If you go with a 500A or higher controller, go with the 2Ga cables (all 10 of them, plus a couple more if you go to 8 X 6V) Especially with 22" tires. I'd also go with the Super-Duty solenoid (400A continuous / 1000A peak) rather than the Heavy-Duty (200A continuous / 800A peak) I went with 2Ga cables and Super-duty solenoid even though I just went with a 400A controller, because I'm an efficiency nut. And I went 7 X 6V (42V) because I wanted to keep every it under the seat and too lazy to shoehorn the eight one in. However, my goal is range rather than speed or torque. |

Re: critique my plan
PQ said they have a bandit DCS motor in stock right now. Im hoping I can get it before its gone.
an you describe how to measure the field and armature windings as you stated? Im kind of a dummie with all this electrical stuff. Im rather mechanically inclined and have always worked on cars but electricity and wiring isnt my best area of knowledge. Noted on the solenoid. I dont neccessarily need a ton of speed but am kind of looking for a nice torque and range cart. So 42v might be better than 48v? Oh here are some pictures of what I have to work with. |

I won't say 42V is better, but if might be sufficient. It depends on what you want. I had all the speed I wanted and all the torque I needed with 36V. I tossed the 7th battery in because it increase the range by over 16% and would keep my average SoC higher, so the batteries will last longer. ------------ If you happen to ever take the cover off the F/R switch, please take pictures. I'd love to see what is in there. |

Re: critique my plan
Thanks.
There are two schematics for DCS carts. One has a diode on the F/R switch, the other doesn't, and I wondered what the one with the diode actually looked like. Now I know. Here is the schematic for your cart. |

He added to his original 6 I believe, if you have to start from scratch go with the six 8's off the bat. It'll leave more room fo' mo' stuff. Have fun man!! I went through a rebuild of a 95 and had one heck of a time. Johnnie here actually helped me a lot with my MANY issues. You've found a great resource. Just follow the rules of fight club...I mean BGW.. Post pics. Always post pics. |

Here is a list of 8V batteries I put together. If you use 170AH 8V batteries, you will have about the same run-time as a 36V pack made up of 225AH 6V batteries. (Actually a little more energy storage wise, but a 48V system tends to increase the weight of the foot on the pedal, so run-time may be less.) Go with the highest AH you can afford, they will last longer. How much longer they will last, roughly equates to the percentage in the right-hand column so you can use it to comparison shop for the best bang for the buck. ---------- My 42V pack is all new batteries. My goal was range and I was pretty sure that a 260AH 36V pack would give me the range I wanted, but the cost of seven 245AH batteries was less than six 260AH batteries, and I ended up with and additional kWh of storage to boot. Now I've just got to get the thing put together. |

Re: critique my plan
I've pulled my motor and hope to send it off to PQ when I get back from my cruise next week (hopefully blackjack will help fund this cart build some).
Is there a method to bench test my stock controller (beings I have no batteries) to see if it is still somewhat salvageable or I could at least try to sell it? |

Re: critique my plan
95 Medalist DCS here,too. You got a jump on me with your build greg.
I started some with a front basket and light.Not pictured yet, Ordered wires from scotty ( on the brown truck) talked with PQ about rebuild on my motor, bought new batteries and I am doing the 42V on mine for duration as my torque is fine with 36. As soon as Turkey gobblers quit I am stripping and painting a camo pattern. Have you thought on your paint yet? So glad you are here and hopefully you learn and pass on the knowledge. Ok, here she is. I have gotten some heat for not posting pics.Sorry for the delay. |
