I have a 15 amp battery charger with an ammeter on it, What does it mean when the meter goes to 10 amps then?
down to zero amps, then back to 10 amps. It’s doing this over and over. I am used to charging a battery and it will start out at about 15 amps then slowly go down to 2 or so amps and the green light will come on saying “fully charged”.
Does the back and forth motion of the meter mean the battery is bad? It’s a deep cycle battery.
That is wrong, wrong, wrong. It shouldn’t go up to 10 amps unless the battery is fairly low, then it should gradually drop to trickle as the battery charges up. Try the charger on another battery, and if it does the same thing, it is faulty. If it doesn’t do the same thing, then there is a problem with the first battery connections, or the battery itself.
