You're going to need to provide some more information.....mostly: what gauge are you using and what schematics are you looking at.

just a basic 60 amp parts store amperage guage similar to the one on the bottom left of the page on the link. for schematics see the top link and the guage lower link. it seems like the guage gets wired in series with the positive on the battery and the positive output from the alternator?? does this make sense?

That's one way of doing it. In short, ammeters must be placed in series with what you are trying to measure(this isn't strictly true, in theory you could remotely mount a shunt and wire to that, but I haven't found that as a option from manufacturers)

With what they are showing, the meter will only measure the current coming in our out of the battery, but not the alternator.

Make sure the ammeter is rated for the current you expect it to carry.

Just to add to what last resort has said. I would solder all lugs, not crimp. I would use #8 wire not #10, and lastly, disconnect battery before starting the installation.

anyone have an example of how they wired in thier guages?
pics would be awesome if possible.
