Delco Remy - a smart choice!
Delco Remy Starters & Alternators - a smart choice.
The Delco Remy brushless alternator design dramatically increases both the durability and the life of the alternator.
Here’s why: Brushless alternators have fewer moving parts, which means less wear on the alternator. The end result is longer life. Alternators pull air from the back to the front in order to cool the internal electronics. This process introduces contaminants to the alternator. With a brushless alternator, there are no issues of contaminants hanging up brushes and causing failures. Without brushes, there are 13 fewer moving parts, eliminating components that wear out.
Bottom line: Delco Remy’s brushless alternator design leads to reduced downtime and longer life.

Diagnosing Starter Cranking Problems
While cranking problems can be frustrating, but identifying and correcting the root cause does not have to be. The first step is to identify the symptoms. In a cranking system, you can divide your symptoms into one of three possible troubleshooting categories:
- Click No-Crank: The solenoid clicks but the starter doesn't crank.
- No-Click No-Crank: The solenoid doesn't click and the starter doesn't crank.
- Slow Crank: The starter will crank, however, the engine RPM is slow to start the vehicle.

How to Diagnose Starter Cranking Problems: Slow Crank
Step 1: Identify the symptoms. Click no-crank, no-click no-crank, or slow crank.
Step 2: Charge the batteries and perform a battery load test on the battery bank
Step 3: If the load test fails, individually test each battery and replace any faulty batteries
Step 4: Then perform a voltage drop test on the starter main cables. The starter voltage drop should be less than 0.5 volts drop total on the cranking circuit
Step 5: Diagnose the problem, by answering the following questions:
Is the control circuit working?
Are battery and cable tests within specifications?
If you answered yes to both of these questions and the vehicle is still cranking slowly, it’s a slow crank issue and the starter needs to be replaced.
How to Diagnose Starter Cranking Problems: Click No-Crank
Step 1: Identify the symptoms. Click no-crank, no-click no-crank, or slow crank.
Step 2: Charge the batteries and perform a battery load test on the battery bank
Step 3: If the load test fails, individually test each battery and replace any faulty batteries
Step 4: Then perform a voltage drop test on the starter main cables. The starter voltage drop should be less than 0.5 volts drop total on the cranking circuit
Step 5: Inspect the control circuit; if the starter does not contain an integrated magnetic switch (IMS), then a voltage drop test will need to be performed on the vehicle control circuit. If the vehicle does not have an IMS, the technician will have to verify that the vehicle’s control circuit is providing voltage to the starter IMS
Step 6: When all systems have been checked and the starter is determined to be the cause, the ring gear should also be inspected for damage.
