Author Topic:   Power Lost After Changing Battery
striper swiper posted 06-09-2009 11:12 AM ET (US)   Profile for striper swiper  
Changed the batteries, engine starts, buy I don't have power to the accessories, lights, radios, etc. Any ideas?

One of the blessings of electricity is its adherence to the laws of Physics (most of the time). Current flow requires a conductor. If no conductor exists, current cannot flow. Check your wiring.

Jim, you mean the battery?

No, the battery is clearly fine since it can start the engine. Perhaps you omitted a connection at the battery. If something was working, and a change is made which produces a different outcome, go back to the change. Look for something as the cause.

Clearly mark all cables that attach to the battery so that your know which terminal they connect to and what their function is.

I took digital pics before and matched to after..but they may have been wrong in the first place, but I do recall all electronics working last season.

The engine has its own battery cable. The boat has its own battery cable that provides the house power. So you should have at least two positive and two negative cables attached to your battery (assumes a single battery system). Because the "house" power is said to be non-existent as evidenced by the fact that all of the accessories are not operational you probably have 1) not connected the house battery leads to the battery or 2) have a blown main fuse or a tripped circuit breaker between the battery and the house power distribution bus.

To search for your problem:

--Begin at some point where you expect to have voltage

--Measure the voltage at that point

--If there is no voltage, follow the conductor back toward the source of voltage until you find the discontinuity.

To perform this test you need:

--a voltmeter
--the ability to check voltage with the voltmeter
--the ability to visualize the circuit and follow the conductors

If you do not have this ability, you will have to hire someone who can perform electrical diagnosis and troubleshooting.

Take a piece of paper down to the boat. Create a map of all the wires...every single one...noting the type, size, and color of all the wires, as well as the connections. Pictures in addition would be helpful. Then, scan and post the map and pictures into this thread.

That is about the only way we could possibly help you diagnose this problem.

If you changed batteries, and everything worked ok before, but does not work now, I'd be willing to bet that you connected something incorrectly at the battery. There are usually only three or four wires that connect to the battery. It should not be difficult to determine if one is not in the correct place.

Note that, if at any point while disconnecting or reconnecting the battery, you experienced a spark or flash, it is likely that you blew some fuses or fried some electronics.

I will take pictures and post them in the morning..if it ever stops raining.

Here are some photo's of the batteries and a view inside the console, I hope it leads to a clue.

Is there any follow-up on this problem?
striper swiper posted 06-14-2009 03:12 PM ET (US)     Profile for striper swiper    
Yes. The problem is the ETA 50 amp breaker part #41-3S14-LN2. I will order the same part and that should do it.
