Coach Batts overcharging
Nice going Yahoo!! This post is from 4 days ago!!
--- In WanderlodgeForum@yahoogroups.com, "freewill2008" > > Fred - this is where geography and a very different coach from mine limit the ability to help. I can give some general ideas. > > One thought: Brand new components can be bad. Have you put a volt meter right on the alternator + terminal? What does it read? If it is 20+ volts, look for another regulator. > > Unless you measure 20+ volts right at the alternator, the new regulator is doing its job. In a 12V system, the charge voltage might be as high as 14.5, and the resting battery voltage can be as high as 12.8. You you must ask yourself where 20+ volts comes from. > > As I understand it, you have house and engine battery sets. Each battery set should be grounded to the chassis, as are the coach components. There is a total voltage potential of 25+ volts between the 2 battery banks. If a volt meter somehow measures the total voltage potential across both battery banks because a ground is missing somewhere along the line, you could see 20+ volts on the meter. This same fault could possibly make the regulator think maximum charge is needed, resulting in the high current reading. > > Try reading from the + terminal of one battery set to the + terminal of the other. Is the voltage above 12.8 resting or 14.5 with the alternator turning? If so, there is most likely a bad ground that has eluded you. It is even possible that the ground problem is internal to some component. > > That is the view from 10,000 feet. The devil is in the details of how your coach is wired. I think that a person with diagrams in front of them or someone with extensive experience with your coach's electrical system is needed to take this further. > > It is late and I could be totally wrong. I often am ![]() > > Bob Griesel > > --- In WanderlodgeForum@yahoogroups.com, "Fred Hulse" > > > > Ground problem would make sense, > > but I am out of ground points to check! > > I don't know where else to look for grounds but will enjoy any suggestions. > > Thanks Bob > > > > Fred > > > |
