Batteries

Postby highroller » Wed Nov 23, 2016 4:01 pm

I have a 05 25 DC with rhe standard battery panel that I think most of us have. It has a switch for each of the starting batteries and a middle switch for the house or 3 rd battery. My electronics and pumps are connected to this battery. Lately this ( new ) battery has been running down and appears to not be receiving a charge. I am putting out 12 to 14 volts from the engins according to my Honda Gage's and have no issues with the 2 starting batteries. I have replaced the battery but need to look further and don't know where to start. Any help would be appreciated . Thanks, High Roller

Don't rely on your gauges for trouble shooting. Use a multimeter and check each batterys' voltage while battery switches are off, engines are off and every electrical device is off and write it down so you know which battery has what voltage. Check the battery voltage by touching the top of the battery post not the cable clamp.

Turn the battery switch on for one engine and start the engine(with proper cooling water of course). Go back and check the voltage on those batteries, again by touching the battery post not the clamp. Write it down under the earlier readings you took for each battery. Now, with the engine still running check the voltage on the same batteries but this time touch your leads to the battery clamps not the posts. Again write it down under each corresponding battery. This will show you if you have a connection problem, corrosion problem or alternator problem. Your alternator should be putting out 13.8v or better. When you finish that battery bank, go to the other engine and it's battery bank.

How is the house battery connected to the start battery?

I believe that it is connected via the battery management system. I will check that out further tomorrow. If I would connect the positive and neg from the house battery directly to the starting battery at least for one trip would that cause any problems . Thanks for all the information. High roller

It's perfectly fine to jury-rig your electrical system to get home. It's not fine to jury-rig it to go out. Just imagine your conversation with the Coast Guard after they bring you and your family in from a cold night adrift. Imagine the Commanders eyebrows when you tell him you used your Rube Goldberg talents to get it going rather than find and fix the problem before going out.....They are not allowed to beat you or torture you but that Commander will have a look that tells you that you've got one coming. :)

Did the 2002's have a battery management panel? Where are the fuel water separators? Mine are where the battery management should be.

When you say standard battery panel with three switches, I am thinking you have a VSR. If not, then disregard this information, but, if you do have a VSR, then you should google how to check the voltage on both sides of the switches with the motors on and off to insure the VSR is functioning correctly. Sometimes the red light could be on, but, no voltage going to the battery.
These things work great, but, they do go bad.
