No electrical power at ALL

Recommended Posts

Need some help. Yesterday while on the lake heard a loud pop thru my stereo and lost all power from the battery. Nothing comes op...checked the fuses and none were tripped. It sounds as though a breaker other than the ones I checked tripped...where should I begin my search?

Did you check the breaker that is by the batteries on the output side of the perko?

I don't have a perko switch (2000 Malibu Sunsetter)...I do have two batteries and traced the wires back to the engine and could not find a breaker. I have to tell you, I'm somewhat mechanically inclined but by far not close to an expert and usually end up fumbling my way around.

You have 2 batteries and no switch? How are they wired? I'd disconnect them both and measure voltage on each one.

Right on...will do. One battery, main, runs the boat and the second strictly runs the stereo but is charged thru the primary. The second battery was installed when I had my stereo upgraded. I'm headed out to the marina to start this trouble shooting headache.

Charged through the primary? what does that mean? Do you have a combiner in there somewhere?

I'd be really curious to see how that is accomplished - is there an ACR or some sort of battery isolator?

I know some stereo shops will just tie the batteries together through a starter solenoid that's tied to the ignition. So batteries combine at key up, separate at key off.

So if one battery is internally shorted then it combines them and kills the other everytime the boat is keyed up?

yeah pretty much. A "dumb" isolator/combiner.

Not sure if this relates to your year boat but I fried an engine fuse discussed here with pictures.
