alternator wiring 68 289
Trying to help a friend with his car, are there any pictures or descriptions of how the alternator is hooked up. There is a red wire running direct from the alternator to the battery but not connected, and the majority of the gauges do not work.

As you can see here, the alternator plugs into the wiring harness, so it is easy to connect properly.

I found the regulator, it does not have any wires connected to it. The alternator is new and looks like a modern one with a built in regulator, and on top it has a quick disconnect with three wires, on the back there is a wire running straight to the battery, not sure how the connection works, the ammeter shows a discharge with the engine running and when the lights or anything else is on it shows a bigger discharge.

Left field question
How do I makle a quick check to see if the alternator is working with the motor running?
In the old days with a generator I would pull a wire off the battery, if it still ran the gen was working, what do you do with an alternator, can I use a test light to ground.
My ten thumbs friend was fooling around with this car and he said the wires sparked when he was hooking things up. I want to be sure he did not fry the new alternator. I just wanna be sure that is working right before I start chasing all the inop gauge wires

You could just go down to Advance Auto and get the alternator your electrical system was designed for. $30 and all your troubles would go away.

That or just take the alt. you have off (2 bolts) and bring it to any auto parts and have it tested for free, then you'd know if he fried it and they'd probably recognize what year/amp it is.
Once you know the year/amp I'm sure someone has used it and can advise you how the hook ups go.
