Experts-Can isolator (solenoid) go bad and why?

[roly_39]

I have a battery isolator (aka solenoid) for my two batteries. In the last few days it seems my rear battery (stinger dry cell) has no juice. My amps play for about 2-5 minutes then one or the other cut out. Even if i play it at barely audible levels for 5 minutes. So it's not cutting out because of volume. There's nothing wrond with the amps or head unit. I'm going to check the voltage everywhere tomorrow but can a battery isolator go bad, and what would cause that? Any other ideas? Thanks...

Did you check if the amp is too warm or not ?
