Default Switch-over

Alright fellows, bare with me here. How hard or how much trouble is it to convert a PDS cart to a Series cart? I know the motor, & controller has to be changed and you have to add a F&R contactor switch behind your legs, but I really don't know about the wiring from there. Do people have more/less problems with these carts vs. the pds carts? Seems like I hear alot of people saying their having a problem with their contactor switch. Are these problematic switches? One last question, is their a cable that would have to be added to the F&R switch, and if so about how much are they? Sorry for all the questions guys, but any help would be surely appreciated.

That conversion is pretty common. It is reliable, but troublesome to diagnose if something does fail (if you are thinking in PDS terms). it's easy for me to diagnose but that's what I do everyday. I would rather work on a series conversion PDS then at a PDS in its original form any day (stock PDS controllers sucked).

Thanks cg, do people have more problems with the pds to series conversion in general?

I'm not overly fond of the PDS drive system in its stock form, but I do like sepex drives.

If I ever decided change my cart into hunting or hauling vehicle, I'd just switch from the high-speed motor currently installed to a high-torque one and go to 48V.

However, if switching to a series motor was, in fact, the best option, I'd most likely install a reversing contactor rather than a mechanical F/R switch.

JohnnieB, are the reversing contactors "that" much better and are they fairly easy to hook up? Going this route would completely do away with the F&R switch wouldn't it? Thanks buddy.

JohnnieB,the reason I'm thinking about doing this is that I'd like to speed it up to around 35-40, and the way I understand, that speed with a shunt motor won't last because it will probably get to hot, and that a series motor doesn't get as hot and would do fine getting up to that speed with a gear change.

kojo....YES they are.....they are the SD of the HD, lol and Scotty has the setup, actually 2 depending on the amperage rating of your system. a SD and a HD. a new HD F&R switch is $140.....the HD Reversing Contactors (for 3-500 amp controllers) is $185 and the SD Reversing Contactors ( 500 amps & up) is #230. if It were available when I did my rebuild over a year ago....that is the way I would have gone.

1. My background is more electrical than mechanical, so running a few wires is easier for me than installing and adjusting levers and rods.

Also, check out the total costs to install an mechanical F/R switch, mounting bracket, direction selection lever and connecting rod in a PDS cart vs installing a reversing contactor and associated stuff needed to make it work.

I'm not into series carts, so I don't know if reversing contactor are all that much better, but my guess is that they are more reliable.

2. No, using a reversing contactor doesn't do away with the F/R switch, it just changes it from mechanical to electromechanical. Of course it is easier to flip a switch than push a lever and the possibility of running the cart when the high current contacts are not fully engaged is almost nil.

Kojo--I don't want to pick on you but listen to the Olman a minute. You are going to spend a lot of money and time to try and get 35-40 mph out of your cart. When you do, you might be really disappointed in the way in the way the cart handles. I built up my EZGO to run about 33 mph (that's as far as I took it because I ran out of balls to push it any further). I found out that at around 30, the cart became uncontrollable in fact dangerous. The more load I had on it, the worse it got (you said you carried 3 people often). I did everything I could suspension wise to try and correct the swaying but could not. I found out that about 25 (you said you are running 26/27 now)as the limit and be stable. I know, I know, you don't have to push the pedal all the way but if it's there, you will try and use it. There are a lot of fellas on the board that have run into the stability issues. If they say they are running 35-40 mph without stability issues, they are not telling the truth. Sold the cart. New one runs 19-20 safely.

Obtaining more torque is quite understandable. Who doesn't want more torque? Running a cart at the speeds you are wanting is very dangerous and is putting you and anyone riding with you at risk of getting hurt or worse.

Take an old man's advise and be careful what you wish for.

OK--off the soap box and back to my rum and coke.

Dang! I just made my 500th post. Guess I need to get a life.

Thanks for the replies fellows, Olman I'm really wanting to do this for the reliability of the motor not getting hot and the torque. I wouldn't mind trying that speed out but if it's going to be squirrelly, I'll stick with where I'm at.
