Have a bayliner 4048. Am getting ac into the panel and the meter is showing 120 volts. No power is being pushed throughout the boat.

1 - isolate the swithc completely
2 - remove the +ve terminal from battery
3 - conduct continuity check between +ve & -ve lines from on any lines possible.

A short is unlikely, as this would either blow a fuse, or cause you a fire.

It does sound like you have something that is draining power constantly, or you have something that has risen in resistance (water environment can cause verdigris and bridging to occur) this is not enough to power the given unit, but certainly enough to drain a battery.
HINT - Apply vaseline to any exposed copper or contact points.

Take the stereo all the way out and hook the black wire to the negative terminal and the yellow and the red wire to the positive terminal on a charged car battey. If it still does not turn on you may have fuse in the back of the deck. If not it's probably fried.

hi thanks for using fixya!!

Is your laptop is brand new? Try to remove the battery. Then, try using your laptop and AC adapter without the battery, you will get the power supply directily from AC adapter. If it works properly, then its okay. Now, try to install back your battery then try to charge it. If not charging, perhaps you need to buy a new battery. However, I suggest you bring your laptop to a service technician to further check the error, before you purchase a new battery.

If you need further assistance, let me know!

Had the same problem with two HDN455's and took them to a local electronics repair shop. They replaced a Zener ZD2 diode for a total cost of $53 and now is working fine.
