| avagadro7@gmail.com: Oct 14 02:22AM -0700 Fresh Odyssey battery, 200 amp alternator, inverter with Ctek chargers, a 400W amp and touch screen receiver. Lights are Hella hi/low units. the alternator should power the system at 60 mph. If the Black n Decker Home Depot inverter is charging a not fresh Optima battery thru a Ctek, in the aux electric system separate from Ford's...the system does not work at all well ...stereo on or not. There are other handicaps eg a need for heavier wiring to the lights. But the inverter's rain is obvious. Light dimming from power drain from the inverter/Ctek/Optima hookup is not draining there just not that level of power going thru the Ctek. So my question, lacking numbers at this time, is the inverter's electronics dysfunctional in this from the battery system ? shall I run a ground wire back to the battery and/or install a diode(s) |

The headlights alone may pull as much as 150watts. Perhaps more. Inverter losses are at least 10% for inverters of this type. Charger losses are even more-so. For a design of the nature you are suggesting, an inverter of at least 1,500 watts capacity is the dead minimum you will need - that comes to a nominal 125A load on the alternator. You will also need bigger conductors than I am guessing you have in place. They will be as thick as your thumb to carry that level of current at 12V - or things are gonnna get warm!

That applies pretty much only to NiCd (nickle/cadmium) batteries that will get a 'memory' if not fully discharged with each use. That memory can be dispersed with care, but it can be a real PITA when the submarine in question is about 5 feet down and 40 feet away in a very fast stream. And why I stopped using them.

That memory > can be dispersed with care, but it can be a real PITA... ** The so called "memory effect" in NiCd batteries is basically a myth. https://en.wikipedia.org/wiki/Memory_effect However, loss of capacity of a NiCd pack is very common and caused by one or more of the following. 1. Over-charging so the cells get hot. 2. Over-discharging so some of the cells go to zero or reverse voltage. 3. To fast discharging so the cells get hot. Each of the above damages cells so some or all of them have reduced capacity or develop a fault condition where the cells discharge themselves in a much shorter time than the others - ie days instead of months. Since all the cells in a pack are charged in series, the cells that contain more charge than others soon become over-charged and heat up while others remain less that fully charged. Such a pack will show low capacity as one or more cells goes flat early. Such a pack can usually be fixed by discharging each cell individually to 1V, but if any cells have developed high self discharge then even this does not work. The term "memory effect" is regularly trotted out when one of the above scenarios needs explaining. .... Phil |

| guijarrosoy <algenta@gmail.com>: Oct 13 10:05AM -0700 Hi, I am trying to take this apart, removed 9 screws ... Not sure how to open without denting the plastic.. Does anyone has a service manual? Thanks. |
