How do I connect 36 volt battery charger to electic golf cart?

If all wiring is factory then check batteries under load. If all good then test motor. With rear wheels off the ground, disconnect the main pos and neg wires from the batteries. Then disconnect the four wires from the motor. You can use a voltmeter to measure the value of the two coils of the motor. Measure between A1 and A2 then S1 and S2 ( sometimes F1 and F2) Should get 1 or 2 ohms. If that good then jumper A1 to F1, connect A2 to 12 volts and F2 to 12 volts, one neg and the other pos. You will get a spark but the motor should start turning if good.

Verify that all battery cables are wired correctly. Should be in series-- neg to pos , neg to pos etc. Then measure total voltage at the main positive and negative battery posts, should be close to 36 volts. If we are good there then measure the voltage at the small posts of the solenoid when the f/r switch is in either position, the key switch is on and the pedal is pressed. I would do this only if the rear wheels are off the ground. Lets say that you do measure 36 volts there, that would mean the solenoid is probably bad.
Now lets say you don't measure 36 volts. Normally there is a small red wire connected to the main positive battery wire at the charger receptacle, it feeds the key switch, key switch comes back and feeds the micro switch on the back of the f/r switch, then to the positive side of solenoid. So connect black voltmeter lead to main negative and with the red lead measure voltage at solenoid. If no voltage keep working back until you find the trouble.
Assuming you have good voltage on positive side, now we check negative side. You probably have a fan shaped black plastic object mounted on the frame under the seat. It's named V-Glide. When you step on accelerator pedal a micro switch in the v-glide closes and provides negative to the solenoid. I hope this helps.

RED IS USUALLY POSITIVE
RED-WHITE IS MORE THAN LIKELY NEGATIVE
TO CHECK SPEAKER POLARITY:
1. HOOK LEADS UP AS I DESCRIBED
2.TAKE A AAA,AA,C,OR D BATTERY
3.CONNECT POSITIVE SIDE TO POS ON BATTERY...NEGATIVE TO NEG END......
4. IF SPEAKER "CONE" PUFFS OUTWARD..POLARITY IS CORRECT. IF IT PULLS INWARD..POLARITY IS REVERSED

white is positive and black is negative, you can also verify this by connecting it up to a multimeter if you hook the white wire up to the red lead of the multimeter and the black up to the black lead it should show a positive voltage, but if you hook the white wire up to the black lead and the black wire up to the red lead it should show negative voltage

OK -- Here's what to do:

REFERENCE PART NUMBERS PER WIRING DIAGRAM:

Note that your specific tractor may use differnt part numbers. You can obtain a Parts List specific to your tractor online, at no charge, from Troy-Bilt at www.troybilt.com -- your full model number and serial number are required.

Key Switch 725-04228 (common alternatives are 925-04227B & 925-04659)Parking Brake Switch 725-1657A (common alternative is 725-04363)

Also note that the starter motor is an engine manufacturer supplied part.

Here's how it goes:
Speaker wires:
grey=right front pos.
grey/black=right front neg.
white=left front pos.
white/black=left front neg.
violet=right rear pos.
violet/black=right rear neg.
green=left rear pos.
green/black=left rear neg.
red=12 volt switched power source
yellow=12 volt constant power source (direct to battery)
black=chassis ground
orange/white=illumination (switched source,not to head light switch)
blue/white=amp turn on lead (to remote turn on lead of amp)
blue=auto antenna (switched power source)
brown=phone mute lead (to cell phone mute lead)
RCA connector leads:
grey lead:
red=right front
white=left front
black lead:
red=right rear/right rear subwoofer
white=left rear/left rear subwoofer
(connect to external amp)
red lead:
red=right aux input
white=left aux input
(connect to external unit)
green lead:
red=right dual zone output
white=left dual zone output
(connect to wireless head phones)
That should be all there is. on the yellow that goes direct to the battery you need to use an inline fuse holder with 30 amp fuse.

I WOULD THINK SO BUT THE BLACK MAT BE THE POS. AND YOU MAY BURN UP THE CHARGER IF HOOKED UP WRONG BUT OTHER THEN THAT YOU HAVE GOT I THINK

I have an EZGO powerwise 36V charger, model 28115-GO3 that was installed onboard a cart. I want to use this charger for another cart, but the charger has 3 wires out. Why 3 wires? One is +, the other -. what do I do with the third wire? The wires are red, black and yellow; two odf the wires are 10-12 gauge, the other is around 16 gauge.

To get 36 volts, number batteries 1 thru 3. connect pos 2 to neg 1, connect pos 3 to neg 2, connect pos 1 to trolling motor controller and neg 3 to ground on trolling motor.
This is only a solution for 3 battery system.
For 4 battery system, connect 4 to 3 pos to pos and neg to neg.
