Low charge light
I have a 2016 precedent that has been flawless until lately, seems that once I. A while the yellow low volt light will come on when the pack voltage is still almost fully charged, 49 and higher volts ( I have a permanently installed digital volt meter on cart), no other symptoms other than a yellow warning light. Light does flash 3 times along with 3 beeps when I plug the charger in. Can this be a sign of something else going on, or is the light on its way out and need to be replaced? The problem has just sort of begun after 3 flawless years. Trojan batteries have sufficient water and are always well maintained.
Any thoughts would be appreciated. |

Re: Low charge light
I would suspect your batteries before the light. Full charge is 50.9 volts. I played 36 holes of golf yesterday and batteries were at 50.3 when I plugged the charger in yesterday evening.

Re: Low charge light
I've had to disconnect the bulb for many folks because they tend to get stuck flashing even after a successful charge cycle for some reason (OBC fault?--I don't have the specific handheld for the OBC itself) And folks view the flashing light as 'my batteries are dead/dying!' so it's fun after a new set of batteries they see that and panic. I just pull the light. When I worked at the junkyard in town we sold cheap ($250) cars and we used to yank check engine lights for the same reason. No e-test here means no law violated.
On Club Cars, we have a 50/50 split on the light working fine albeit flashing for whatever reason, and the other not working at all, so it's never a reliable way to check SoC. Best get a LED readout meter (NOT one of those bar graph things) |

Re: Low charge light
I do have a on board digital vile meter installed. Volts are fine, 50.3 or more, the yellow light is not flashing, just solid light. Seems to have started after I washed the cart and did wet the light, it was lit after the bath.

Re: Low charge light
Should never be solid. At best it would stay on 20 seconds, off 10 seconds, on 20 seconds and repeat.

Re: Low charge light
The 2016 Precedent does not use an OBC, the ERIC system does not have those blink patterns.
It maybe related to water still trapped somewhere near the Controller. The White Controller on Your cart measures and calculates the remaining battery capacity based on current and voltage sensed by the Controller and activates the light if it thinks the batteries are getting low on capacity. You said the voltage was 49V+, but what was the voltage during acceleration? |

Re: Low charge light
Oh that explains it. I've only dealt with one ERIC based Precy before and the charger was more garbage than the EZGO PowerWise QE. Cart was dead. I was confused by its lack of an OBC at the time. Customer didn't want to pay to replace charger with a better one or another ERIC--it was the third one in his case, and that plus batteries mean no-go on repair so I never knew how the light worked on them. Gave me a rather untasteful view of the future, that and the expensive troubles of the EX40 later models of them and the Carry-alls turned into. We aren't equipped with the tooling for what I'm seeing slowly creep in lately. The one with the EX40 I never did figure out.
