Coach Batts overcharging

[GARY MINKER]

The likelyhood of a milled copper and brass shunt failing are near a negative number unless you run 300% current through it and melt the solder joints. The wire crimps, and hardware are more likely problems. If you need to measure DC in a line or branch, get one of these less than $100 DC clamp on ammeters. They tell you the current and the direction of flow. Don't leave home without one. gary 85pt40 --- On Sat, 11/20/10, freewill2008 wrote: From: freewill2008 Subject: [WanderlodgeForum] Re: Coach Batts overcharging To: WanderlodgeForum@yahoogroups.com Date: Saturday, November 20, 2010, 1:14 PM Fred - In that case the instruments could be giving you a faulty reading. The ammeter uses a shunt which could have failed. That might lead to a faulty voltage reading as well. Another possiblity is a relay (solenoid) failure that is causing the charging system to max out, although I would expect that to show up on both house and engine systems. This leads to the controls mentioned in the other reply, so that is a good place to start. In any case check the shunt on that house ammeter so you know the reading is accurate. Good luck with it.
