Re: MCOR WOT Voltage/Low speed shutter/Speeds..
No you can recharge with as little as 15-30 min run time , thay may start creeping up a
little ! |

Re: MCOR WOT Voltage/Low speed shutter/Speeds..
As I wait for the hydrometer I decided to try the MCOR voltage test again with a new Ideal multimeter from HD. I set it on DCV on 20 and got -9.12V at full throttle. Is that right??? I put the black end of the multimeter on the negative side of battery #4 and the positive end on the yellow wire right before the 3 pin connector at the MCOR. Does my reading sound right? Other posts stated the voltage should be around 7.75. Not sure about the negative/minus either?
Also the low speed shuttering has gone completely away a couple days ago. This is the first time the cart has been getting any drive time for 1.5 years. Hopefully they come back. After a ride today and then subsequent charge my pack read 51.7V a couple hours after charge. I also tried this: http://www.buggiesgonewild.com/elect...ars-mcors.html and the MCOR seemed to click after pressing the throttle down 1" as compared to the 2" depressing before. However I had to undo this mod as it started (in my opinion) fooling the MCOR and making it think the throttle was open a little upon arming arming and then subsequently shutting the throttle down as a safety mechanism. The override for this was to turn off power at the key and apply back pressure on the throttle pedal with one hand and turning key on with the other. That would get me going forward again until I let off throttle. The adapter or mechanism that the nub attaches to in the above thread picture has a lot of play. In fact the whole throttle and brake linkage seems messed up to me. I am hoping the batteries and the MCOR are ok so my problems are isolated to the throttle linkage. The linkage really looks like a cluster and I dont even know where to start? Hey Scotty are you in the Riverside area by any chance? Is that your shop in your sig link? Thanks again guys |

UPDATE!!! Re: MCOR WOT Voltage/Low speed shutter/Speeds..
Results are taken approximately 1.5-2.5 hours after a short charge after a short 10 minute ride.
Results: Pack 52.1V Battery #1 = 8.69V, 12.75, 12.76, 13.00, 12.95 Battery #2 = 8.69V, 12.75, 12.65, 12.75, 12.75 Battery #3 = 8.70V, 12.75, 12.65, 12.75, 12.90 Battery #4 = 8.70V, 12.70, 12.77, 12.80, 12.95 Battery #5 = 8.68V, 12.85, 12.95, 12.85, 13.00 Battery #6 = 8.67V, 12.85,12.70, 12.67, 12.70 All batteries checked well into the green for the SG tests. I think I have good batteries here? That would narrow my problems down to my throttle linkage and MCOR. I think.... |

Re: MCOR WOT Voltage/Low speed shutter/Speeds..
These readings a re TOO healthy. 1.277 is 100%. You have taken these readings too soon after charging. The batteries need to settle for an hour or more after charging to get good readings.... How long ar far does the cart run for before reaching the 50% recharge voltage mark?

Re: MCOR WOT Voltage/Low speed shutter/Speeds..
Scotty,
Ok I will test again in another hour or so to give it plenty of time after charge. The thing is I dont know when exactly when the charger cuts off so I am guessing how long. Should I retest in several hours or tomorrow? I dont know exactly the history of the batteries for the 1-1.5 years they sat. He might have left the charger plugged in which would be a battery saver right? Ill post back later with updated SG results. It should be noted the forward throttle doesnt work unless I turn the key off and apply backwards pressure (towards me) to the throttle pedal and then turn on. then the forward throttle actuates until I completely let off the throttle again. linkage or mcor or both?? When I was taking the rubber mat off I might have abused the pedals a bit?? I also dont know how long a run to the 50% mark. I can try that its just difficult due to the throttle actuation problem... Thanks for the help! |

Re: MCOR WOT Voltage/Low speed shutter/Speeds..
Honestly Boomer, these carts are not the best throttle linkage setup or electronics. The performance is not the best either.... Your batteries are suspect just because they have endured a long period of inactivity. New ones may not be a whole lot better, speed wise but, better on longevity. Hope this helps

Re: MCOR WOT Voltage/Low speed shutter/Speeds..
Thanks for the help Scotty!
i just re checked my MCOR and it is giving me a good read at 7.49V @ WOT. i know the linkage is out of whack now. I got to figure that out next I suppose. I am starting to think it is wishful thinking that my batteries are ok. They may test ok but they have likely been dumbed down a bit... Back to linkage 101 for now I guess... Thanks for all the help! |

Re: MCOR WOT Voltage/Low speed shutter/Speeds..
A load test is the true test. Not may can load test 8v batteries but, that is essentiually what you do when you hit a hill Can you connect the meter to the pack and get some readings from fully charged and 1 hr rested ( settled Time) to the hill climbing voltage?
