So, where were we?
Even though the manager said I could throw away the chargers, I would never get rid of parts for anything until the original problem is resolved.
Today I got a call from the other manager that they got the new charger and it didn't work, and there may have been a bad wire in the golf cart and I should bring back the chargers.
In my defense, I tend to believe what people say and they said the charger was bad (well, maybe that's not a defense), plus it was 90 or 95+ degrees out and humid when I was there, and crowded in their little golf cart garage, and in general I'm running on only 5 cylinders anyhow.
Also the charger they had is supposed to signal when there are battery problems, but I didn't know about that before I took the charger home, and at home I never took the current charger out of my trunk, only the one that broke 10 years ago that does nothing. I don't remember if the flashing lights earlier matched "Battery Problem" or not.
Details They had received the new charger by UPS and the ammeter never moved. The owner called the vendor and was told to look under the seat, where the batteries are, and she or her manager or her manager's buddy who hangs around sometimes noticed a wire from one battery to the other had come out of the crimp connector. So he put it back in the connector and crimped it some more.
Then they used the new charger which she checked every hour and it was always off, and she'd have to unplug the golf cart and plug it back in to get it started again. When she said this it sounded really bad, and I'm very impressionable so I thought it was bad, but even while I was there I started to have doubts and now I realize that I don't know how early in the day the golf cart failed, two weeks ago. It might have been early so the batteries were mostly charged, and those few minutes early today were enough. In fact it occurs to me now that she said things which indicate that it rarely takes more than 30 minutes to charge at the end of the day, so the new charger is good, but it's a cheap model (see question in previous or next post) and she says she has 30 days to return it, for any reason I guess.
So we reconnected the charger they were using until 2 weeks ago and it seems to work fine. Unlike the el cheapo, it shows how many minutes it takes before before it turns itself off, unles the time is under 31 minutes. In that case it just shows 30. We left the garage for a while and when we came back it was off and said 30, but the time was probably less.
The golf cart has 6 6-volt batteries, big like the size for a car. I showed her where there was battery "salt" on the batteries in two places and told her how to clean it. She already knew about water level, but I don't know if they use distilled or not.
Also, catalog said that if you have 24 battery caps, you have 48 volts worth of batteries, but the drawing showed six 4-cell batteries. It turns out they do they make 8-volt rechargeable batteries the size of car batteries. But the drawing confused her anyhow and she thought she had 48 volts. It was hard to count the battery caps because they came with a device that loosened all three of them at once, and made it hard to see the actualy caps. Apparently golf cart batteries are also used in some electric cars still. http://www.electric-cars-are-for-girls.com/8-volt-golf-cart-battery.html
Her father owned and ran this business until about a year ago, and died, and now she's learning to run it.
Anyhow, they have the chargers now and other than giving her a little more advice, I'm out of it. Fine.
Thanks for all your help you guys.
