Default ezgo 2008 shudders

Hi All,
I have just put new batteries into a 2008 TXT and when I put my foot on the throttle it shudders at take off but then goes okay in both forward and reverse
Not sure what it could be.

New batteries are not charged until YOU charge them. Let the charger finish the cycle, then drive the cart.

Read this.

http://http://www.cartsunlimited.net...n_Methods.html

While there, read everything with the word "Battery" in title.
Lots of good info.

Even new batteries should be at 75% of their potential. Unless they have been shelved unattended for 6 months they should run the cart. Unless the cart has some serious cable & F&R resistance .... Unless one battery is installed backwards. Yes, backwards. I have gone out on that service call
Check the pack voltage at the main + and - and report back here

Hi
Recharged the new batteries and it still shudders when you initially take off in either forward or reverse.
Once it's going it goes along okay
Any ideas?

Possibly one battery dropping a cell under load. Connect a digital battery meter to the pack and watch it as you try to go quick from a stop..... what does the voltage start at and drop to?

Thanks Scotty
I put my multimeter on and when I put my foot flat it went from 38.2v to 33.34v
I think may be the hub or the brushes.
Does that sound feasible?

Hi all
Well the problem has been solved. It appears that some moisture must have got into the motor and because the cart had been sitting a while some of the brushes were sticking. I cleaned the brushes, skimmed the computator, general clean and all is good.
I hope this may help someone in the future.
Thanks to everyone who gave advise.
