I have a Promar 2 bank charger for charging my (2) trolling motor batteries 24V.
The issue I'm having is only 1 indicator light is coming on where it's always been 2 displaying.
It was fine on my last fishing trip when I plugged up, both batteries charged completely.
Cleaned all the terminals, applied light coating of dielectric grease, checked fuses, water level good.
Multimeter is at daughters house 😕
Batteries are 4 yr old interstate.
What ya' think ?
Bad indicator light ?
