Re: Alternator wiring and selection (for replacing a generat

How about, instead of a tractor, I would like to put one of these alternators on a '56 International truck. How would I go about hooking THAT up? It has an idiot light already in the dash so I suppose I could use that instead of the diode. But how about the rest of the connections? There is a lot more wiring in a truck than on a tractor, so I would not want to screw this up!

Click the link below.
This is the simplest diagram for wiring in a 10_si I have found.
Scroll about halfway down the page.

You ask "How would I go about hooking THAT up?

If you choose the Delco 10SI family of so called three wire units and its Neg ground 12 volts

Big rear main output wires to the Load (NOT battery/starter supply) side of the ammeter if it has one....and Id use at least 10 better yet 8 gauge wire.

Small side 1R terminal can (among other possibilities) get its initial excitation voltage from

Feed to the ignition coils input terminal which becomes hot when ignition switch is turned on with an in line diode to prevent run on if ign is turned off,,,,,,,,,,,,,or an in line series resistor,,,,,,,,,,,or a small incandescent tail/marker indicator lamp,,,,,,,,,,,or a combination lamp and resistor so it still works if the light burns out. Theres other possibilities if needed but the coil or ignition switch output is often used for initial alternator excitation.

You ask "It has an idiot light already in the dash so I suppose I could use that instead of the diode.

YES a small incandescent light (if wired correct) can work to prevent run on just like a diode or resistor would

You ask "But how about the rest of the connections?"

The alternators small 2F side terminal is for voltage sense and it can work if jumped direct down to the big rear output stud or better up to the battery itself.

Or you can use a one wire unit with its output up to the ammeter if it has one

It's still the same, the alternator doesn't care what it is mounted to.

A standard alternator does require 12v negative ground.

The wiring is the simple part, what can cause more problems is the mounting.

It is essential that the alternator be mounted straight, solid, and in alignment with the existing pulleys. Also the alternator will likely come with a narrow pulley that is probably not going to match the pulleys on the older vehicles. Sometimes the original generator pulley will fit, just be sure to get the spacers right.

Quoting part of Steveís reply ...A standard alternator does require 12v negative ground.... The question I have does this truck already have a 12 volt system? Just googled the subject and an article I read about a Ď57 IH pickup said that was the year they went to all 12v. If this was a 6v truck then all the light bulbs will need changed including those in the instrument panel, Heater blower, electric wipers if not vacuum, turn flashers Iím sure a couple other items I overlooked. There are some specially made 6 volt alternators but my guess is they cost some bucks.

One thing I forgot, Iím not sure how well a 6v gas gauge will respond to 12v.

Just use the common Delco 10si like the alternator use on say a 1980 Chevy pick up truck and then wire it like you would on a tractor simple as that. I did that on a 50 Chevy pickup and it worked just fine

Usually on a truck, do to the distance between the battery and the alternator - and one-wire does not work well since it cannot sense battery voltage. 3 wire hookup is not any more complicated on a truck then on a tractor. In fact, it is easier IF the ignition switch has an ACC and IGN terminal. If so, no exciter diode is needed.

This truck is definitely not a place for one wire alternator.

With 3 wire, as JDEM notes, the #2 sense pin on alternator can, if needed, connect back closer to or at battery to compensate for voltage drop in the longer wires.

He already has the "idiot lite" so just connect generator end of lite connection to #1 pin on alternator.

Google "one wire alternator". They are made for the odd installation in hot rods, boats, etc.
