07 CC Precedent speed issue

bruce_d · 10-17-2011, 05:27 PM

I bought a used 2007 club car precedent from an individual. It has the 4x12 battery system. I went to a dealer and had them put 4 new batteries in and ordered a speed code. They installed the speed code and when i use it i only get to 16 mph on a flat service. If i go uphill it goes to 10 -12 mph and downhill it can get to close to 19. If i have passengers it is even slower. I took it back and they "verified" that the speed code was installed and that the throttle was set to 100%. They performed a battery charge/discharge and found not fault in the batteries. Then they put in a good motor/control unit with a speed code for testing and it peformed the same - they then removed the units. They gave up. Any thoughts or suggestions would be extremely appreciated.

I have the same cart but I have not bought the speed code. Mine ran 16 MPH on flat surface stock. I have since upgraded the tire size and have not took it for a spin with my GPS. Something doesn't sound right. I would think you should be getting 20+ MPH with the speed code.

I have a speed code but not sure which one. With 6yr old 12v, I am getting 17/18mph on the flat.

check to see if you have your tire pressure correct. it happened to me also I was going 16 and I knew I use to go 22, I didnt have enough air in my tires. I now have 20 PSI in the and I am back going 22.

Yup, check the tire pressure.

Personal Speed Mode 4 is 19.6 MPH. I've attached a picture showing what you should be getting with stock tires. There are several things that can effect this and one of them is dragging brakes or rolling resistance. Can you push the cart easily with your hand back and forth? Is it lifted? What is your pack voltage once fully charged?

What speed code are they speaking about... 3 or 4?

If you do have Private Speed Mode 4 and they in fact switched with another cart both the motor and controller... you must have a resistance problem or a battery problem, or cable problem, (even though you installed new batteries.) Seeing you took it to a dealer, the same dealer that said they did the work... hummmm... they should look for brake drag, battery voltage, low tire pressure... hummmm... something fishy here

....... My thoughts exactlly! If it's on speed code 4 then it would atleast go 19.6 going down hill before the regen kicks in!

Mine is set to the default golf course speed and I am getting about 16.5mph on flat pavement. The 23" tires are helping there but I would certainly expect it to go faster with a higher code setting. Hard to believe low tire pressure could rob you of 4mph without you realizing they are that low - but it's worth a look. Also, hard to imagine the dealer didn't think to check that.

Thanks for all of the replies - I checked the tires and the average PSI was around 14.5. I inflated them to the recommended 22 PSI. I believe it has helped drastically - here is the current status

19 - 20 MPH - going downhill or an extremely flat service
15 - 17 MPH - going up a slight incline
11 - 14 MPH - going up a moderate incline
8 - 10 MPH - going up a extreme incline

All of these are with just myself in the cart - my question - Is this reduction in speed normal when going up inclines?
