Charger or computer or what?
 

My wife came home in the golf cart last night and barely made it over the golf cart bridge. I plugged the cart in and got no response from the charger. I figured that either the charger was bad or the on board computer was gone. This morning I borrowed my friend's charger and plugged it in. The charger came on, shut off and came on again as it should. I assumed it was a problem with the charger, but when I went back out to the garage a while later and the charger had turned off.

I plugged it back in and it came on again, shut off and turned back on. I then noticed that it's only pulling four amps. I thought this was strange so I plugged my charger back in and got exactly the same result. It came on, shut off and is pulling four amps. I thought that with the pack being so low, it should be pulling maximum amps.

Any idea what might be going on here?

Been there....done that... It's just not worth it....

Traded electric in for a Gas model......

So far, so good....

Just a suggestion.....

PS. paid for 6 new trojans $$$$ last year and didn't even get the price of the batteries for the trade.....go figure

Charger, Batteries, or Computer
 

Well, you didn't like what I said, so guess you will figure it yourself what the issue is, the relative costs, and what to do. Certainly not worth pursuing more and getting into potentially ugly comments - have a good year and have fun carting around TV.

Why does every discussion or question about a golf cart devolve into this argument?

Does anyone have an actual helpful suggestions?

By the way, I took the cart out and ran it for five miles. I plugged it back in and it starting pulling 15 amps. That was about two hours ago. I just took a look and it's now pulling two amps.

It appears that the problem has corrected itself. If it is the onboard computer, the fact that it's a triple digit fix is not helpful. Is it $100 or $999? There's a big difference.

I wasn't arguing with you, I was just sharing my experience. Happy trails.....

Carefully check each battery individually, use a hygrometer to check the specific gravity. If you find variations, you may have one or 2 bad cells. Check all of you connections at the batteries. Take each one off use a battery terminal cleaner, clean and replace, and tighten. Try charger and see if the results change. Also, I forgot to mention note ant cells that appear to be low on water, this could be an indication of a bad cell.
Hope this helps.

If it were me, I would want to know the voltage of the batteries after the charger shut off. Also the voltage of each battery after that 5 mile ride.

I would invest at some point in a nice multi meter.

That said...

There is a procedure to reset the OBC.. It seldom, but sometimes gets results. Reset the club car OBC

OBCs always struck me as a ridulous amount of money. Almost worth getting a new 'smart' charger and bypassing the thing.

Battery Boys sells a Bypass charger for around $400.00 that controls the charging cycle. The computer controller in your cart costs almost $500.00 to replace. I have changed both our carts to the Bypass charger and our problem is solved.

PS, also sold both the old chargers to recoup most of the cost.

Its not almost 500 to replace, you may have been dealing with the wrong place. Low 300 dollar range.

You can get an DPI Accusense Charger made in the USA that floats for the low three hundreds.
