EZGO Textron Controller

[girard415]

I have an EZGO Textron 27647-G01 that I have acquired from my dad. I plan on rebuilding it and giving to my son for Christmas. I am new to carts so I am lost. Here are my issues.

1st The Power wise charger will not come on I checked the batteries and I have 33.8 VDC from the postive of B1 to the negative of B6. I bypassed the relay to see if it even worked and it came on but the DC Amps showed nothing and I checked the AC amps and it was reading 32-33 Amps. Is the charger any good?

2nd The cart will not go. I have been troubleshooting for two days now but I am not sure if I have made any progress? I think it might be the ITS or the controller. I have .5 VDC going to the micro switch of the pedal box and when depressed the switch closes. I get 0 VDC to the ITS either side depressed or not. I checked the controller (Curtis PMC) and there is 0 VDC on the white and black wires.

I have found several diagrams on the forum but none for the 27647-G01. I am using the 28646 diagram which seems to have small differences.

Any suggestions would be great.

First of all your batteries are stone cold dead! They should be 38 volts at a very minimum to be fully charged! The cart will do nothing until you get the batteries charged! Ok, first make sure they all have water just covering the plates ( no more ). Bypass the relay and let the charger run for a few hours. Reconnect the board so the charger runs automatically. Now leave it alone for the 12hrs or so it will run and shut itself off! You won't be able to test anything until your batteries are up! Here's a helpful chart:

Good to know Thanks!

Looks like you may have a 2003 0r 4 cart. Which drive system do you have? directional shift Lever = series. Or a toggle switch on the dash = PDS


Can you check individual battery voltage and post it here 1 through 6

[girard415]

It's not a 4 four cart and it has a lever near the seat for forward and reverse.

1= 5.85
2= 4.28
3= 5.78
4= 5.80
5= 5.83
6= 5.87
Total= 33.6

Battery #2 may have a dead cell? However 33v should be enough voltage to start the charger so you may have a charger problem also. Can you try your charger on another cart or try another charger? Or take the charger to a shop for a run test? Can you check the voltage at the receptacle by probing the terminals as the charger does when you plug it in?
The batteries need to be fully charged before the cart's drive system can be tested so that is where you should start.
You have a series drive cart.

If I was to replace battery #2 and charger (if it is not working after tested) then I should be able to check the rest of the system. Could i add one 12 volt battery in the place of 2 6 volt of testing purposes?

JohnnieB i think I need a circuit board 19950G2 or 19460G1 When I got the charger the relay wires were jumped together and would only work using the timer. After hooking back to the relay, the charger would i]only stay on a few minutes before shutting off the batt bank was 32v

[muffinhill]

The charger is a ezgo textron total charge with a green front 20484

There may be one or more bad batteries in that 36V pack, if so the charger may not act normally.

What are the individual battery voltages?

----------
I don't know if those control boards are still available.

You might be able to retrofit a more modern control board into it, one with a built in back-up timer and bypass the mechanical timer.

In all honesty, it is time to get a modern charger rather than using a 50+ year old design.
