Charging problem 85 Club car 36 v

MetalWolfExotics

Hi all I am new to the site and am in need of some advice on a 1985 36 volt club car
Batteries were replaced and charger seems to be working but only three batteries are charging
The batteries on the drivers side are bubbling and are taking a charge and the three on the left are not charging the 3 that are; are working to go forward but the other 3 for the reverse are dead have tested them with voltage tester and hydro test

So my question is why will only 3 charge and 3 will not even charge or bubble is there something i am missing in the charging system does the F&R work as a resister on this
All batteries are new and car was working but it was slow forward and fast going backwards
If I switch the cables to run it, it would go fast forward and slower backwards but I guess the problem now is the left side batteries not charging

Any suggestions or input will be greatly appreciated

Apologies’ if I Am not asking the question correctly ? I have a charging problem which I can not figure out.

just not charging half the batteries but not bad batteries

I can charge each battery separately and they will hold charge.

On an 85 CC you have positive and negative charger wires coming from the charger receptacle to the batteries. It is clear you have these connected wrong. Get a volt meter and check this out, the charger should connect to 36v not 18v as it is now. You will damage the batteries charging this way.

The other problem can be easily corrected by simply taking the Green cable that comes from the bottom of the F&R and looping it back to the F&R at the bottom where the red cable connects next to it....

But first and most importantly get the charge wires on the right terminals. Every electric cart owner should have a voltmeter.

If U can clean batteries and cables, send a picture of the entire pack and well tell U what is incorrect ?

There is no green cable at the bottom of the F&R switch I will get picks but I have checked wiring over and over according to the schematics’ I found here on the site

Thanks the better the detail the better !!!

Do U have a volt meter (digital preference) $20 at Lowes .
Even If U dont need it for this , with a electric cart U will eventually need it.

Give us more info if you want help. What all is connected at the bottom of the F&R ?
You have 2 different speeds in forward and reverse so you must have 2 different power supplies. Regardless of cable color?

Check the wiring diagram. That might help you.

Here are pic's

The first one is with the F&R switch out and attached to the fuse under plastic cover

in the other pics are how cables are conected to batts in sires from right bank to left bank there is one power wire that goes to the two batts in the center to the F&R switch then the white wire and black wire go to the motor
then from the F&R sw. to the right bank of batts batt cable then there is a red bat cable at top right of F&R SW. to the motor. will ad two more pics with out words attached to the pics hopfuly you can click on and enlarge them.
