Well can we at least try testing the cart female plug for voltage just to make sure. Just the + & - in the socket to see what we've got. Take you 2 seconds...

I will check it first thing tomorrow afternoon. It is about 10 miles away from me. I keep it where i hunt and trap every day. I should be able to test it and let you know something by around 4:30pm tomorrow. I would go now, but it would be illegal. I sure thank you for all of your help.

Default Re: Charger Problem?

also try resetting the OBC !

" Reset the OBC and try charging again.

OBC reset
1.Remove the positive and negative cables from the pack
2. Place the F/R switch in reverse
3. Slowly press the pedal down and hold it for a minute or so. Reverse buzzer should sound until all the power has dissipated from the OBC"

As you changed your cables did you clean your battery connections well? They should be shinny when changing cables. Also make sure charger terminals are clean a, use small brush, then clean them in the cart receptacle, pipe cleaner, and some baking soda works well, rinse clean, dry. Is the charger er coming on, going off after a minute, then coming back on? This is controlled by the OBC, if doesn't come back on you can force charge 2 ways.
1) open charger, and bypass the voltage sensor.
2) run a wire to the last battery terminal to the carts plug receptacle.
Either of these bypasses the OBC so will have to monitor the state of charge yourself because you can cook your batteries. Another thing is to check the water in your batteries if a cell is low or dry they will not charge. Or you may have broken a battery terminal on one of your batteries.

ok, here is the story....Checked voltage at female plugs for charger and it was 36.7v. then i reset the OBC and checked it again and it was 48.4v. Plugged charger in and it charged for about 10 minutes and went off. Checked voltage at female charger outlets again and it was 36.7v again. I did the whole thing all over and got the same results. Does this help or do you need more info? I sure appreciate y'all. I would have REALLY been screwed without y'alls help.

Thanks,
BAF

The positive lead off the receptacle on my IQ goes straight to the main/last battery (+), which on your cart should be Battery 1, the right rear battery. The negative lead on my IQ receptacle goes to the OBC then to the controller. Somewhere when you re-wired your cart you placed a wire or cable to the wrong position or you blew the OBC. At this point you'll need a schematic to trace back wiring to the OBC as well as the controller to make sure they are correct. If resetting your OBC set the receptacle back to it's proper voltage and your battery pack is wired correctly you should be fine, (but you're not.) So one more test to see if the OBC is bad. See the attached picture and WITH YOUR CHARGER UNPLUGED FROM AC AS WELL AS THE RECEPTICAL, jump the lower wires shown in the picture, not the red or blue top wires, then plug it into AC, it should hum, then plug into DC and it should charge. In this position the charger WILL NOT shut off so stay with it and see if it will raise the voltage of your pack. If it does then your OBC is bad or wired wrong.

BE VERY CAREFUL WHEN DOING THIS SINCE YOU'RE PLAYING WITH HIGH VOLTAGES!!!

Thanks, Scubabud. I will check that tomorrow afternoon. If I did screw up my OBC, where can i get one(affordably if possibly) and how hard are they to put in?

Default Re: Charger Problem?

Question- I started looking on ebay for an OBC in case that is the problem and found a used one...The guy says that it was taken off and replaced because of a 'motor upgrade'. I have read a lot on this forum about upgrading motors and have never seen anything about it requiring a different OBC. Is this guy just trying to sell this thing and full of you know what or have i missed something?
