Default Motor or Rear end??????

OK, I got my charger and batteries issue problem under control. Now I have a new issue. When I depress on the pedal the 36v motor jumps around like its trying to engage but nothing. If I jack up the rear end tires turn. When I start off slow it will run in till there is any kind of grade. Any ideas

burnt brushes in the motor? Is this the cart that you were having extremely low voltage issues with?

It's the "run til any kind of grade" comment and I seem to remember low pack voltage that has me thinking burnt brushes/Armeture......

Low voltage = High amperage = parts cooking off......

Its definitely something to do with were the motor connects with the rear end. Droped the rear end cover all gears look good. Anybody have a break down of it? and yes this the cart I was having low volts with.

That's funny I just found an old blog with someone that had the same problem.

"All of this work being done and you haven't even tested the batteries? You must like wrenching!

If I read this right, your batteries sat for a year, but seemed to take a charge? Get a digital multimeter on those bad-boys and take some voltage readings. Also, let's get a reading at the cart charge receptacle. Even better yet would be a proper load test. Neglected batteries can show proper voltage and have NO capacity to pull a load.

You're so right! I did all that work, and found no problems. HotRodCarts mentioned the batteries in his first response, but I was in a wrenching mood. Lesson learned - I found a battery with only 4.15 volts. I also cleaned and tightened all connections. I'll look for a posting on the load test, I know I saw that subject discussed. Hey, at least if I have a rear end problem in the future, I know how to take it apart!! Thanks for your input, this site is fantastic!!"

I guess Ill put the load tester on all my batteries and see what I get. Well at least the rear end oil will get changed and " cover glass beaded and painted at work"

Well, I did the load test on my batteries and 3 out of the 6 came up NO GOOD but I got the rear end pan beaded and primed. Tomorrow new batteries and we'll see what happens. Anybody have any luck with the napa 8144 or 8146's???
