Alternator

Post by LJohnson » Sat Feb 28, 2015 8:41 pm

I've ran a wire from my alternator to my volt gauge, but haven't connected either end yet; I'm not sure which connections to make.
The back of the alternator has two spots for wire connectors to slide onto, and I'm not sure if I need to use the one on the left or the one on the right.
Also, on the bottom of the voltage gauge, there are two small studs with nuts. One of them has a "S" stamped next to it and the other has a "I". Which one do I use?

The alternator is a kinda cheap "Driveworks" remanufactured one wire from Advance Auto

You only need the big wire hooked to your system, (hot side of solenoid), hook the voltmeter to a ground and the ignition switch accessory post.
The one wire alt will energize when you rev the motor the first time

Like RL said, just the big wire is enough to run it, the 'I' is likely to be the indicator light (dash light) which should come on when you turn on the key and go out when it is charging once you start :salute:
I was told I was wrong, once (not sure I believe it though)

Airboat experience so far, limited to having bolted a gyrocopter to a flat bottom punt.... but THAT.... is about to change, bigtime :-)

If it's a voltage gauge it goes like this..

When you fire it up it will read the battery until you spin it up to around 1200 rpm and "excite" the regulator.

Yup... Starting it wont show needle movement.. Rev it up and watch it punch over.... I idled around for a LONG TIME with every light burning... and had a dead battery in a few hours.. Had to learn the hard way.. Not all of them are "Self Exciting".... So, just know whatcha got.. LOL
