Buggies Unlimited High Step V-Glide Bypass
What is the purpose for the High Step V-Glide Bypass? Does it not use the resistor coils at all or just at top speed? I'd imagine that despite the name, the V-Glide is still used.

Re: Buggies Unlimited High Step V-Glide Bypass
Looks like it is using a solenoid to replace the direct (high speed) circuit on the V-Glide. This would keep the heat down and may help keep the wiper arm to not heat up as much.

Re: Buggies Unlimited High Step V-Glide Bypass
Back to the original OP question....
It sounds pretty good for long cruising times as no current is going thru the wiper arm, but it seems if you press the accelerator too quickly, the by-pass solenoid will close at a very high current and could wear out pretty fast. |

Re: Buggies Unlimited High Step V-Glide Bypass
Same current goes through the main solenoid, so it would suffer the same fate. I will guess that since the motor is already being supplied current through the last resistor, the actual arc in the solenoid contacts wouldn't be that great. Even if you press the pedal as fast as you can, current is already flowing to the motor. The part of the earlier V-Glide that I don't understand is why the lowest speed coil is connected directly and does not go through the wiper switch? I would think this would be dangerous if the solenoid was to stick closed! Seeing that there are three unused terminals on the wiper, I would have had the lowest speed coil connected to the wiper switch. It isn't for arcing reasons because the last unused terminal is making full contact when the micro switch closes. Ahh, mysteries that make me go Hummm!

Re: Buggies Unlimited High Step V-Glide Bypass
I was referring to the "make" current, not operating current.
When the main solenoid activates, all of the resistors are in series with the motor so the "make" current is reduced. With the by-pass solenoid, when it closes its "make" current is whatever was going thru the v-glide at the time it activates. It seems like if you press the pedal real fast, the by-pass solenoid will activate while the motor is still not moving too fast and at a very high current drain. I agree welded solenoids on non-controller carts can be quite a surprise |

I am not a sparkler guy but it seems to me resistors or motor the current would be the same. |

Re: Buggies Unlimited High Step V-Glide Bypass
I understand what you mean about the solenoid engaging on either a stopped motor or at least barely turning one. Just think of the load on the main solenoid when the kid puts the selector to forward, floors the pedal, and then flips the key on!!! He also thinks it was Cool to be going in reverse and flip the selector to forward with the pedal floored!!! Needless to say this is probably why the controller carts were set up where you couldn't do this! I was working on a 90 Club Car for a friend. This is what I finally discovered about the short life of the V-Glide and solenoid! Needless to say friends kid no longer touches the cart!

Technically though, the way that circuit was drawn, the by-pass relay activation +48v was coming from the v-glide side of the main solenoid and there was no 6ga cable on the last pad (the one that activated the by-pass solenoid). So if the pedal was WOT, the main solenoid would have to activate first and have its current reduced by the coil resistors, before the by-pass solenoid could activate. |

Re: Buggies Unlimited High Step V-Glide Bypass
So true! I think that a lot of changes are made just to prevent improper operation, and I am not singling out just kids!
I worked on one CC that the owner was using the throttle pedal to hold the cart on a hill. We know what the end result of that was! Getting the person to understand that this was harmful was a task for me! "Well, I do it all the time in my car", was what he told me. I had to block the wheels on the cart and hold the pedal a little to show him that the resistors will get red hot if you do this! He now understands and is having no problems with his cart. What I find sad is that the shop he was taking his cart to didn't tell him this! He told me that before he had moved to this area, he had replaced several resistors and the board. |
