Another "power drive 2 charger not shutting off"
02 Club Car ds 48v cart
Charger is not shutting off after 16 hours of continuous charging When I plug end into cart charger waits about 10 seconds or so, clicks, hums, and amp meter jumps to 8 amps. It trickles down over this long 17 hour period and hangs at about 4 amps and will not shut off. Here are my voltage readings. Pack voltage on charge after 17 hours. Charger @ 4 amps 61.2 volts Batt 1-- 10.29v neg lead Batt 2-- 10.46v new batt Batt 3-- 9.98v Batt 4-- 10.11v Batt 5-- 10.06v Batt 6-- 10.13v pos lead 30 minutes after charging Pack -- 53.2v Batt 1-- 8.90v neg lead Batt 2-- 8.81v new batt Batt 3-- 8.79v Batt 4-- 8.85v Batt 5-- 8.89v Batt 6-- 8.88v pos lead 1 hour after charging Pack -- 52.6 v Batt 1-- 8.82v neg lead Batt 2-- 8.69v new batt Batt 3-- 8.74v Batt 4-- 8.77v Batt 5-- 8.81v Batt 6-- 8.81v Battery #2 in my list has been replaced with same brand of battery because the old one ended up with a dead cell. The original ones are only 1 1/2 years old and have been maintained well with only distiller water. I've also tried resetting the obc but still hasn't changed. |

I know the more knowledgable guys will want to know the readings after 12 hours off charger. From what I remember your voltage may not be reaching cut off voltage for the system.

Well in that case I still have 10 hours to wait to get the 12 hours off charger reading which puts me at about 2 am.😴

I don't think you need to wait up until 2am. Just check them in the morning. I think the thing is to wait at least 12 hours. That allows the surface charge to bleed off.

Re: Another "power drive 2 charger not shutting off"
Those are great readings IMO, is the main neg going through the obc? Is it the only main neg, or do you also have a bypass cable on the neg. if not there must be something wrong with the obc. It tells the charger when to turn off. I'm just guessing from what I have read on this site. Hopefully someone who really knows will jump in.

Re: Another "power drive 2 charger not shutting off"
Yes the main negative lead passes thru the obc but I will triple check to be sure. The only other negative wire on the whole battery system is the new digital lcd volt meter that I mounted on the dash for measuring pack voltage, so the kids know when to put it back on charge. This has been going on since before I installed this gauge though.

Also wanted to note that I haven't seen my battery warning light turn on in a very long time
