Factory drawings of original GOLF CART BATTERY wiring doesn't matter much at this stage.

There seems to be only one way to solve this ongoing issue for you, Bob. Please post a few PICTURES of your battery compartment (with the seat removed) - and someone should be able to stick arrows on the photo YOU SUPPLY; to show which is your pack POS (cable might be Red, or with a Red cap or band - but not necessarily); and which is your pack NEG (normally Black).

Here are my batteries . They are yellow maintainer wires. hanging downside of cart, [temporary].One is 110 a/c, The other is the battery side of the "Save a battery" maintainer-----wrapping around into cart. Front of cart is to the right of these snapshots thanks for any help. [yellow papers] shows battery cables, negative; left side- the positive; right side, Anymore please let me know, i'll put up more pics. I believe scooterman, you have me on the right path bob s and thank you

The maintainer is connected correct, the big confusion is whomever re-wired the cart used all red cables to make the jumpers, normally they are black but that isn't a problem as long as you know it.
I think you need to test your batteries, If you have a voltage meter, temporary connect it to the First(+) & the last(-)(the only black wire. Set your meter to DC and range it high enough but as close to the 50 volts range. You will need to take a ride on the cart and read the voltage as you ride it on a Full charge. write down the starting voltage, then put the pedal to the floor and see how low the voltage drops write that down and then top speed write the voltage down and post it here. get some help to do this and be safe.

If this is too complucated, then charge batteries and let sit over night, purchase one of these
Amazon.com: OTC 4619 Professional Battery Hydrometer: Automotive Amazon.com: OTC 4619 Professional Battery Hydrometer: Automotive

And test each battery cell, allowing for temperature and post that. What I'm getting at, you need to test the batteries and see if they are any good, I think probably you may need some help with this. It appears that someone has rewired things in this cart, who knows what they did, it may be very helpful to get a cart dealer to look at your cart or someone trustworthy to really look into it.

ok scooterman BTW these are (gel batteries deep cell). thank you for your help once more. the long red wires are right [hookup], but i will get the black ones soon, at the correct length.That was a quick reply thank you. My wife and i rode in the back seat ,our son his wife, our new grandson, And last but not least, our medium size dog- wriggled down between him and her, in the front seat dog loves to ride.When i got home after 2 mile ride the batts showed ; 51. 5 volts when we left. 48.6 volts we we returned. the maintainer has been on the cart for 3 days now.Its staying at 48 volts even. i think the "battery maintainer" just maintains the 48 volts , from now til i use it again. Lites are all flashing properly .Yellow may just keep going til it gets ready to stop flashingI guess, again thank you ,for seein me thru this my friend. bob scharphave agreat summer scooter .

That is a big voltage drop for just 2 miles, even loaded down. I suggest yo use the batteries up until they don't go anymore and then get 6 8 volt batteries for that cart. Use the regular charger for daily use and the maintainer for long storage.
Also remember when you buy new batteries make sure to closely follow the battery break in procedure, it is posted in the Link I made here for you. This will help you get the most from your batteries.

Good luck and enjoy the cart.

These maintainers are designed for FLA batteries. They may work on Gel Cells but that's not what they were designed to work with. Optimum charging is different. Gel Cells can't outgas like FLA's.

I suspect that they claim they can charge them but I feel the same even though is say clearly they can. Also not sure the powerdrive can charge them properly also.

Thanks for helping him scooter - I was out last night. Yep - it sure looks like those poor ol' Gel batteries are really struggling with the amp-load imposed by the cart. Not surprising really, or carts would have switched to Gel years ago if they could have.

Good advice to just use-'em-up over time, and replace with the deeper/stronger 8v wet golf batteries for the future.

You can't go wrong with Trojan T-875's or Crown CR165's.

Default Re: 48-Volt Battery Maintainer

I left my save a battery unit hooked up and running yesterday. My battery leads and jumpers are all red as well but I just hooked the black charger lead to the one the out going wire where the battery was stamped NEG and the red one to the other out going one that said POS. It worked out okay. My concern is that I had run the cart about eight miles that morning looking for piggies. I put the cart on the PC2 as long as I could but when I was ready to leave out it still showed at the three to four amp markings. I unplugged it, plugged up the maintainer and it was in the charging mode when I left it. I just hope it has the ability to bring it the rest of the way up to full and keep it there as I won't be back there for about two weeks.
