yellow battery light coming on with new batteries

[fishbooz]

hey guy's ...I just installed 6 new Trojan 875's a few months ago , the cart has sat for week or so and I tested the pack voltage last night and was at 51.1, I got in the cart today and as soon as I put the cart in reverse and hit the throttle the yellow battery light came on and then went back off, I thought the battery light only blinks if the batteries are low ??? is this normal? cart drives fine.
Thanks

Not sure as my cart now runs a different controller but the light may be telling you that there was an AC power interuption since the last time the charger was plugged in.

Thanks Teecro ...I recently put a madjax controller on it, I wonder if that has anything to do with it ? hoping no battery problems ....my wallet wound has not even healed yet from the $650.00 I just spent on the batteries.

it doesn't make any sense to me why it would come on as I never let the batteries get even close to 50%. but let it sit (after a full charge )with the charger unplugged for a week and it comes on, although only for a second and then goes back off, I did put an aftermarket controller on it so maybe that has something to do with it ? I heard someone say something about a cart going into sleep mode but I don't even know what that is , maybe that could have something to do with it , hoping Sergio or David may know or Scotty .With my luck it could be anything and would not involve any cheap fix ,LOL . I am getting one of Scotty's SOC meters , I like the idea of that , can't wait to get it installed

I don't put a whole lot of faith in that light. Your multimeter will tell you a lot more about your batteries than that light will. It could mean the charge cycle was interrupted, but I've seen OBCs fail and randomly turn that light on for no reason. Once you get Scotty's meter, I'd unhook that light. Nothing you have done to the cart has anything to do with the OBC or that light.

I think the OBC will power off (go to sleep) if it does not sense the charger DC plugged in for more than 3+ days.

The first time you drive the cart it will blink the light. It has only happened to my cart once because my wife forgot to plug it in to charge on Monday and I used it the next Friday.

I like the digital voltmeters, but I would leave the warning light connected as long as you are still using the OBC to charge.

Thanks David and Sergio !

Batteries’ voltage drops below 48 volts when there is no load on the batteries (the vehicle is stopped and there are no accessories on).


Our 03 IQ cart will come on/flash some times at very light pedal and going over a spot that flexes the cart. I just guessed the OBC sensed a low voltage for a second as the light doesn't stay on all other conditions are a series of flashes 10 with a 4 second pause,...

NOTE: The battery warning light will flash quickly, after inserting the DC plug, if the charger relay/voltage suppressor has failed in the closed position.

That is exactly what mine did.
Thanks
