Solenoid upgrade

toledo20

I have a older 36v. DS series with the v glide and heat coil things , lol a later 80's model I belive.
I converted to 48v. A whIle back and I keep welding the 48v. Solenoid shut.
Want to upgrade to a HD 400 amp. I guess.
My question is what's the resistor that is recommended to use with this do? And should I purchase it?
Also my solenoid is a bottom mount, where it screws down to frame in a vertical position and I see most HD solenoid s are side mount, not sure if my wires would reach.

Ok, maybe I worded that wrong.
What does the resistor wire do when you upgrade to a heavy duty 400 amp solenoid?

The pre-charge resistor lets just enough power pass through to keep the capacitors charged in the controller at all times. Without a resistor, the controller would see a sudden rush of power every time the solenoid clicks. It helps to prolong the life of the controller.

Toledo,

When you converted to 48V, did you install a controller, or are you still using the coils for your speed control??

toledo20

Yes still using the coils.
The only mods I did to the cart was added batts. 3- for 36v. Then I read on here that it can be converted to 48v. So i added a 4 battery and a 48v. Solenoid but that one has welded shut.
I have 4 - 12v. Batteties used for solar panels with onboard marine battery chargers which has been working pretty good.
I did have to change v glide swing arm once.
Other than that, I think I need to get the HD 400 amp solenoid.

The original resistor coils were designed to limit the current based on 36v, so if you do a lot of slow speed driving it will be pretty hard on the v glide.

For mostly cruising, this mod will totally bypass the v-glide when WOT:

Thanks for that info!
So you are suggesting that for this 48v. Conversation I should added these extra solenoid plus the 400 amp solenoid?
That would be a extra 48v. Solenoid has in diagram in tagged post?

Sergio

The best option for running 48+ volts is to use a solid state controller.

Adding the one extra 48v solenoid will by-pass your Vglide at full speed and extend its life.

You should avoid prolonged partial throttle driving as there is no way to know how much contact the wiper arm is making with each pad inside the vglide and it could easily melt the pads.
