I picked up a NOS Aqua Meter ammeter for 20 bucks the other day, and may want to use it. I already have a hole of the correct size in my dash, which is currently filled with a trim indicator that is of no use to me. Since my motor doesn't have tilt/trim, I may as well use the hole for something useful.
So, the question is, how do I hook it up to my motor. I know that I need a 10 guage run of wire between the "BAT" post on the guage and the common lead on my battery switch, but what do I hook the other post to?
I also know that the other post on the meter goes to "the alternator," but I am not sure how to translate that into the wiring layout for my motor. I'm thinking that it should be connected to the #5 post on the engine's terminal block (see diagram, below), which receives 12VDC from the rectifier.
I've already seen some of the threads that talk about the value of an ammeter v. a voltmeter (already have one of those), but none of them seem to provide information on how to wire the ammeter. Any thoughts by the members will be appreciated!
PS: If you can't read the wiring diagram because of the image size, right click, save picture as, and then view with Windows Picture & Fax Viewer, which has a zoom function.
