Default Re: Is There An Electrician In The House?

An interesting conversation and I only scanned the pages.
If the cut-out (reverse current relay) is solid state (diode) I would expect a .7v drop.
Batteries are like large condensers. Battery physics dictate some terms. I would expect a good 6v battery to draw a very lot of current above 7.5v. A bad battery may go to 9v on little current. if you put a line charger on a battery and it draws little current and goes to 18V (12v battery) the battery is suspect as a 6v would be..
You can run lights at 9.2/9.3V but above that you will blow them out
To achieve those voltages as mentioned the generator will not be seeing the battery.
Also and I doubt it given the info provided something to consider, if the generator is negative ground it will be in series with the battery. Yikes.
Lastly, wiring (I own an electrical shop but don't do wiring) too much information will make the task very hard to solve.
