Re: Club Cart motor/other problem?
Not exactly true.... The 0-5K Setup was a "2-wire" configuration. The 5K-0 setup was a "3-Wire" configuration. They work a little bit differently. If you got the throttle situation resolved, yes it will work, but only on a fully charged 36 Volt battery pack, but as soon as they start to discharge just the slightest little bit you're going to run into an undervoltage issue in that controller. It wants to stay within the range specified on the controller, a partially discharged 36V battery pack won't be in that range. Undervoltage is terrible for a controller.

The Curtis 1204-4xx is listed as a 36V-48V controller. "Undervoltage cutback" doesn't occur unless the pack drops below 21V. Even at 21V, it cuts back on the PWM duty cycle to protect the batteries, not itself. A low 36V pack will not hurt the controller. -sj (Illustration shows converting 3wire from 5-0K to 0-5k or vice versa. 2wire output swap would just be a matter of swapping the non-wiper wire to the post at the other end of the resistor string. Converting a "2wire" to "3wire" adds a wire to ground at the empty end of the resistor string.) |

Re: Club Cart motor/other problem?
Yes there are several different regen controllers. 5 actually. A Regen1, a Regen2, an IQ, an IQ Plus, and an Excel. But this is irrelevant to this post as this car is a series car. As far as the amperage is concerned, I can't answer that post for sure because I've never tried this, however I would assume based on my experience that it would have a significantly weaker output running less voltage. I may be wrong and I'll admit it if I'm proven wrong, but there's several factors here telling me no it's not going to work properly. Another one that just entered my head is as follows... About the throttle control. Basically what it's doing is sending voltage into the V-Glide switch from the controller, adjusting it by the use of resistors inside the V-glide case, and sending the modified signal back to the controller. A 1210-410 controller is going to expect a modified 48V throttle to be put back into it. Ohms are ohms, it doesn't matter what it is, but those ohms reduce voltage by resistance. My point is, 5000 ohms of resistance on a 36V input will result in a weaker throttle output than it would on a 48V input. But try it and see. I'm anxious to see how it turns out.

Re: Club Cart motor/other problem?
One more thing I just noticed, might be another clue.
Ususally, when pushing the accelerator (F or R), it actually does start to move, ever so slightly. I mean you have to listen and pay attention or you would hardly notice, but that kind of tells me everything is engaging (or at least trying too). To better explain how I ususally get this to work. When I push the accelerator and it will not go. I slowly push it until I hear the solenoild click and I get that little effort to move, if it doesn't, I back off and keep doing the same thing. Eventually, as I slowly push the pedal it take off like normal. The other item worth mentioning. When it doesn't move, and you keep pushing the accelerator, if you push it too fast, it sometimes it will 'catch' and surge forward fast just a bit then stop again. I don't know if that helps any, this is very strange problem. I have NEVER been stuck in this thing yet! But I sat there for 2-3 minutes before pushing the pedal wondering if was ever go! Thanks again for all of the help |

This is easy to confirm on a scope. The throttle pot on a 1204-410 was set to give a 75% duty cycle at 48V. Lowering the input voltage to 36V without disturbing the pot gives the same 75.3% duty cycle. -sj |

Re: Club Cart motor/other problem?
I don't have a scope. I don't have anything more than a multimeter. Therefore, I turn this thread over to Sonicj so I can watch and learn. I clearly don't know what I'm talking about. It's all yours man. I've given my opinions, use them if you'd like.
