How to hook up a GM 3 wire alternator?

I understand how to wire up the 3 wire alternator. The number 1 wire goes to a resistor or dash light and is suppose to glow when not charging. That…

Where is the charge warning light on a GM alternator?

But this is not a simple bolt-on conversion. The 10- and 12-SI units use a different two-wire connector plug on the rear of the alternator. The Number 1 wire on the 10- or 12-SI is connected to the charge warning light on the dash. The Number 2 wire is what is called the voltage sensing wire.

What kind of regulator does a GM alternator use?

Assuming you want to upgrade, we’ll take a couple of the more common options and run through the wiring variables. The original 1960’s GM alternator employs an external voltage regulator. This alternator (10-DN), uses a flat, two-prong connection at the back of the alternator.

Is there a wiring harness for a GM PCM?

Novak can simplify this harness, removing unnecessary circuits, consolidating circuits, rerouting and labelling for a simpler 5-6 wire hookup into any Jeep. This sensor will allow you to run a conventional cable drive speedometer and send critical speed data to your GM PCM for proper powertrain operation.

Can you use an amp gauge on an alternator?

Amp Gauge Wiring 1) Always disconnect the ground lead from the vehicle battery before wiring any gauge. 2) Classic Instruments’ Amp gauge should only be used on vehicles with alternators rated at 60 Amps or less. Using an alternator with higher output capacity is dangerous and could cause a fire.

Do you need a harness for a 6g alternator?

NOTE: This harness will work with 6G systems that have a gray colored regulator. Alternators with a white not allow feedback to the PCM. Used to install a new 3G alternator in Ford vehicles. Will light or switched ignition source.

What should I do about my factory GM harness?

One of the most significant things an installer can do to speed the conversion process along and keep the headaches at bay is to have their factory GM harness simplified and modified. Novak has gotten this wiring process and PCM programming down to a science.
