What is the EZGO part number of the meter you have?

Pins 1(+) & 2(-) connect to the battery.
To get meter to light up, you have to connect Pin 4 to B+. It can be switched B+ from the keyswitch or tied to Pin-1 so it is on all the time.

Be sure your batteries are fully charged before connecting meter, otherwise it might not read right. (Some of them assume 100% SoC is whatever the voltage is when they are connected)

I am putting ScottyBs battery meter in to replace the stock one. Do I splice the existing wires that were on Pins 1 & 4 (both red) to the red on the new meter? Then connect the wire from Pin 2 (black) to the black wire on the new meter?

You can use either red wire but not both. One red wire has constant power and the other is controller by the key switch.

Admittedly, I don't know squat, but if I use the red to the key switch - it will still read an accurate charge on the batteries? The LED I am sure has little effect on the batteries, maybe I should use the constant. Which one would you use?

[scottyb]

The direct line to the batteries is more accurate. The key-switch offers some resistance which results in a lower reading but, the resistance is constant so if you have a handheld meter you can determine what the difference is and compensate. My test meter has been on for many years without a problem.

I say the constant. I wired mine that way and whenever I walk by the cart I can see at a glance what the pack is reading.

Constantly on is excellent for checking charge at a glance - especially convenient on seldom used carts that discharge while idle. Or carts family uses that occasionally gets put away with being plugged in

My dash mounted DVM is connected directly to the main battery pack terminals and it has been running 24/7/365 for the past six years and is just as bright now as it was when installed.
