How do I identify my GM alternator?
How to Identify GM Alternators
- Examine the Delco-Remy alternator. The alternator is located at the front of the engine, usually toward the passenger’s side of the block.
- Locate the Delco-Remy identification tag or sticker. At the factory, Delco-Remy places an identification tag on the alternator housing.
What wires go to an alternator?
The circuit comprises three main wires: battery positive cable, voltage sensing wire, and ignition wire. The ignition input wire is attached to the engine. It conducts electricity from the engine to the alternator while the voltage detecting cable senses the voltage and is attached to the rectifier.
What kind of alternator is Delco CS130?
Delco type CS130 series, 105 amp, self exciting (one-wire) internal voltage regulator alternator with finned “Iceberg” rear housing for better cooling and longer life. Self exciting alternators only require the main battery wire to the back of the alternator to work. They do not require an ignition activation wire like standard alternators.
How do I change the alternator on a CS?
The alternator bracket may need to be modified and you will probably need a couple of washers to take up the space between the alternator bracket and the new alternator. Most of the connectors for the CS alternators are four wire but will only use two of them and the wiring is the same as the SI.
What is the wiring hookup for a cs-130 alternator?
The wiring hookup is the same for the CS-130 and CS-130D alternators. On both the CS-130 and CS-130D alternators must have a resisted ignition wire to the “L” terminal. Resistance can be obtained thru use af a resistor or you can use the no charge light as the resistor, the light bulb will supply proper resistance.
What is the difference between GM Si and CS alternators?
Well, the GM SI alternators are easier to get and have higher outputs.SI is short for Systems Integrated which means the regulator is inside the alternator case. The CS alternators are even better!
