82 Club Car Inoperative

jackbob

Just bought the cart in June used, had truble going up my driveway hill, then began lurching, smelled a carbon smell, then was dead on the road. Batteries appear good, suspect motor brushes but the guy I bought it from stated he just replaced them for the sale.

Any suggestions on what is wrong? Pushing accelerator now cart does not moved, or vibrates just slightly.

start with batteries and cables...............check water in batts. if needed add distilled water only to 1/8 inch over lead plates.........charge cart up till charger shuts off than take voltage readings from each battery and load test each battery.......also grab and tug each cable to make sure they are tight and very clean where they bolt on......................what your posting really sounds like a battery issus........what brand and how old are they...........................

They are Stowaway Golf Car batteries circa Jun 2003. Could not find manufacturer or dealer source on the web for the brand. Took SG readings shown below.

Cell: 1 2 3 V
Batt#
1 1260 1260 1260 6.33
2 1250 1260 1260 6.33
3 1175 1175 1160 6.22
4 1185 1240 1250 6.31
5 1260 1265 1255 6.34
6 1260 1260 1265 6.34

Spent 15 hours of troubleshooting / cleaning connections and a week of individually charging batteries, taking SG reading only to determine Exide Stowaway Golf batteries are OK, charging to at least 85% of new ones (no bad cells) . All switches are good, speed control, Fwr/Rev switch. All connections are good. Battery stack at 38 volts. Current does flow to the motor, speed control resistors get warm.

All the cart does is sit there or the motor lurches trying to get some traction (in FWR or Rev), then I smell a carbon smell like the brushes.

So before I tear into the motor - which I'm not crazy about (never worked on motors before), are there any suggestions?

The posted wiring schematic also does not match the wiring to the motor and the batteries on my cart, but since it was working assume wiring OK until I can see a better schematic and determine the motor connection.

Anyone have this issue before?

Is your cart fitted with 5 solenoids with 4 resistor coils in the rear between the batts and the motor?
Try the link below for a series motor diagnostic >>> If the motor works then your problem is in the solenoid and microswitch system.

Does it do the same thing in reverse?

scottyb

He says does the same F&R and he smells carbon. 'New brushes installed for the sale' and smelling carbon now is a red flag.

You may be on to something Scottyballs............

Yeh, I'm on to sumthin....I'm sittin' on em

Why do these carts only use 4 resistor coils? Should all 5 fire in sequence or is the 5th one for something else? The reason I ask is because I am only hearing 4 clicks when I push the pedal to the floor (with key off) and my cart lacks power. I dont think it will push the larger tires I just ordered (22/11/10)..

Thanks
