"High Speed Switch" ?
A neighbor recently bought a golf car that had an interesting toggle switch on the outside of the body. He was told that, "You get up to maximum speed, then toggle the switch to get a much higher speed".
The car is a 1992 Club Car DS, 36 volt with solid state controller. It's basically a stock car, and not "road-ready". It has no turn signals, etc. First, there's an Off/On toggle switch mounted on the outside of the car, about where your left hand would drop as you were riding. There's a linkage attached to the throttle pedal assembly that appears to activate a make/break or on/off switch. This linkage appears to be professionally-made and is not just some cobbled-together thing. Then, there's a battery-type solenoid (maybe 100 amp) mounted on the frame near the motor. So, near as I can figure out, when the throttle pedal is fully-depressed, that switch is "made". Then, if you toggle the manual switch, you activate the solenoid coil. Now, here's what I'm really confused about: The solenoid contacts are connected to the motor with #8 gauge wire, so that when the solenoid is activated, motor connections S1 (Orange) and S2 (Blue) are shorted together through that #8 AWG wire. My neighbor hasn't tried using the switch, yet. And, I'm not going to suggest he try it until I understand a little more about what happens when you short those two motor terminals together. Of course, there's another question I have. If this is a legitimate modification, can I do it to my 1986 DS with solenoids? The motors and the motor connections look identical from the 1986 to the 1992. Can anyone help? Thanks Chuck |

Re: "High Speed Switch" ?
its called a speed system or shunt not very good on the motors. it shorts out windings in the motor to give more speed

Re: "High Speed Switch" ?
If it was my cart I would throw the whole system away and save replacing motors and solid state controllers every so often. If the switch and wiring is left on sooner or later some one ( kid, wife, neighbor, or yourself if you are my age and forget ) is going to say OH WONDER WHAT THIS IS FOR and then you take the chance of burning up a motor at the very least??

Re: "High Speed Switch" ?
Agreed. They are bad for the life of the motor... Western used them for a short while but learned after replacing lots of motors that it was not worth the gain...

Re: "High Speed Switch" ?
Thanks to you all for the replies. Sounds like it's the typical, "Ya' don't get anything for nothin'."
I guess I don't understand enough about these motors but it sure surprises me that they'd even run (for a little while) with the field windings shorted out. Thanks again for your insight and suggestions. Chuck |
