6v-12volts?

[rossbart]

One more quick question:

I am not familiar with a positive ground system - this is my first. I appear to have everything running 12 volt (except coil which is resisted down to 6 volts. I want to add some 12 volt electric guages in this interim time so I can monitor water temp, oil pressure, etc.. On a positive ground system do I need to wire everything in reverse of what I'm used to with automotive and 12 volt negative ground? In other words, on the guages, do I need to ground the positive wire to chassis and the black wire to the battery negative circuit with an inline fuse on the battery negative circuit?

I would assume so but am certain that there is a vast storehouse of knowledge here that I'd like the benefit. Thanks for any help to the new carrier owner.
