controller swap question

weracemx

ok i have a 1992 cc ds 36 volt curtis controller i have everything i need to make it 48 volts have a charger 8 volt trojans
my question is i have a 48 volt club car curtis controller can i swap that in and be ok or do i need to buy a difrent controller .
trying to do this as cheap as possible just want the power of 48 volts compared to the climbing power of a 36
thanks in advance

You should be Okay..... the stock controller may only be 225 amp. and this wil limit your 48v experience

Is it a silver or black controller? One is 5k-0 ohm while the other is 0-5k ohm. Both will work, might have to mod the throttle.

ya i figured it out it is actualy realy easy to mke a 36 volt cart into a 48 volt cart thanks for your guys help

Did you upgrade the solenoid to 48v? Cables to 4ga?

weracemx

ya very simple upgrade

And what are the performance differences with the stock 225amp controller?

weracemx

well to be honest if you had to buy the parts it wouldent be worth it to use the stock controller but if you can get one cheap you get about 4 miles and hour over the 36 volt system and i would say at least a 30 % difrence in hill climbing capability.
and you dont have to change the motor or use 4 gauge cable
the purpose of the 4 guage cable is to limit resitance that is buit up by heat generated by the extra amps a higher amp controller provides.

so if someone wanted to do it here is how
first change the vglide from 0 to 5k to a 5kto 0 this is done by a simple swap of the wire hooked to the first fixed contact ,switch it to the last fixed contact .

next you need a negative feedback wire from the vglide to the m- of the controller this wire is hooked to the thrid lug from the bottom of the vglide

next change the soleniode to a 48 volt hook up the wires exactly the way they are removed from the old one

next change the controller and hook it up the same way you remove the wires from the old one you will notice that some 48 volt controllers do not have the a2
lug this is no prob you can either take the two left over cables that are suposed to go to the a2 lug and just bolt them together or you can replace the two cables with one cable .

next replace the 6 volt bats with 8 volts making sure all conections are tight and wala there you have a 48 volt club car .....
takes about 35 min


hope this helps someone

weracemx, thanks for the simple 36v to 48v conversion in clear, plain steps. I'm new to the forum and have heard about this but this is the first step by step process. SHOULD THERE BE A STICKY!!!!!!

Now my question is, what equipment would someone need to buy to perform a complete 36v to 48v conversion. Also, if you're listing these, could you also include a round about price for each item.

Appreciate the help, never knew there was so much depth to golf carts.

Welcome to BGW!!!
Cancov, you are wooting and barking up the wrong tree. This conversion didn't come close to the power and torque improvements that are possible because he used a 225 amp controller There is really no point in doing this with any less than 400 amps. You just won't have enough amperage available at any one time to see the 30% gains that are possible...... Sticky? I don't think so
