Ezgo Model 830 3-wheel cart- new to me and too slow...

7fa

Recently picked up an EzGo 3-wheel electric cart. Name plate says it a model 830. This is my 1st cart, so looking for a little help (excuse the rookie questions...)

Right now its working but seems very slow and it loses speed quickly on even mild inclines. Checked battery voltage (which reads 24.8v) and also removed and cleaned all the battery cable connections. The center connection of the resistor bank is broken, but that controls mid range speed right?

-Name plate says it is 24v and it has 4-6v batteries, but the GE motor nameplate says its 36v?? Is this normal?

- It has seven solenoids. I hear 4 solenoid "clcks" during full range of the pedal. On the 1st click the motor does not turn. 2nd and 3rd clicks are progressively faster. 4th click is right at "full throttle" but it does not sound like the motor is going any faster with that last click.

Really not sure where to start. Understand it is an industrial cart and may be designed to be slow, but it this thing is painfully slow right now. I have had zero luck finding any type of manual for this online. My goal is something to ride around the neighborhood and take to campgrounds with us.

I tried to attach pics but it would not let me as a new member. Let me know if you need any other details and thanks in advance for any help!

cross referencing your model 830 they are about the same as pargo

i am not sure on your model .. but a Pargo has seven solenoids and it also has a 830 model

that being said the diagram for model 800 series pargo has seven solenoids
2 forward , 2 reverse , 1st speed , 2nd speed ,& 3rd speed
but it is a 36v system

you do need to fix your resistor coils

does it look any thing like this ?

Thanks for the response.

Yep- the wiring diagram you attached matches up to how mine is setup with the exception of only have 4 batteries instead of 6.

Any suggestions on where to start troublehshooting?

Is it normal for the 1st and last solenoid cycling to have no effect?

On my resistor bank, the center connection to 2nd speed (aluminum connection bar about 1/2" wide) is broken. Can this be soldered back together?

Finally, there is only room under the seat for four batteries, but would it make sense to pull two of the 6V and install 2-12v deep cycle batteries to give me 36v?

Appreciate any other suggestions

I don't have any experience with resistor carts, but I'd think solder would melt. If the coils are intact, I'd look for a mechanical connector, maybe like one that's used on residential ground rods.

you may be able to upgrade to 36v

added : you should be able to upload photos now

may be like yours ?

Thanks... Yes that looks very similar to mine, although my charger is under the dash and the batteries run front to back under the seat. Pics attached now.

I realize it's not a speed demon, but it's rated to haul 400lb load (two adults can sit on it- seat backrest folds down for one rearward passenger- not shown in pic). With just me on it maybe goes 3-4mph (fast walk can keep up with it). Just seems like something is not working as designed.











Any ideas what to check to confirm whether or not something is worn out or not functional?

no it is a low speed factory cart ... they were made to be used in plants.. so they did not want them to go fast ... your feeding 24v into a 36v motor so your good

ok makes sense. Just thought it would have more torque than it seems to have. With another person on it or any type of load I doubt it would move much faster than I could walk.

Any mods I can do to make is a little faster? Not sure how I could upgrade to 36v because there is only room for 4 batteries. Would swapping to 4-8v make enough difference to justify the hassle? I guess I could do 3 12v deep cycles, but understand they would not last as long

You'd have to make sure the solenoid coils can handle higher voltage, but higher voltage = faster.
