Re: 12 volt negative ground conversion
One thing that usually gets left out until the end is the ammeter. Needless to say you will need to reverse the wires on the ammeter to get it to read properly. There is another thing you need to do with the ammeter. There is a wire that runs to the ammeter. It is probably 10 gauge. Run a second wire in parallel to this wire and connect it to the other terminal on the ammeter. Now half of the current will go through the ammeter and half will go around it. Your ammeter will now only read half of the current that is going to the battery. This is something you will need to remember when reading your ammeter. Since your new system is probably going to put out twice the current that the ammeter was designed for this is what you will want. There are also reproduction ammeters designed to handle 30 amps but I have been told that all of the reproduction ammeters leave a lot to be desired.
