There it is, that blinking red indicator light. Once again, your stator is dead, right when you were ready to start producing.
After you put your frustration aside, you need to investigate the cause. Do you need a quick fix? Is it just something small? Or are you in need of major stator repair?
To answer those questions, you will need to know how to check.
How to Tell When You Need Stator Repair
When you are having difficulty with your large industrial engines, checking your stator is the first thing you should do. The only job it has is to provide extra power that is then used to charge the battery.
If there is not enough power generated in the system, your battery may drain over time.
What to Check
To begin your troubleshooting process, you must first unplug the stator connector that runs to your engine. Once it has been dislodged, you will be able to test the stator for both voltage and resistance.
To start, you will want to check for continuity from the connector to its terminal tabs to see if anything goes to the ground. In order to check this reading, you will need to adjust your multimeter to its Ohms settings.
The multimeter leads should next be used to check the tab’s resistance. Organize yourself by first checking A to B, then B to C, and finally A to C. For each of these tests, your multimeter should register under 1 Ohm.
You will want to make sure that you account for resistance between leads. Any reading over 1.5 Ohms is officially considered to be faulty.
To be sure nothing is going to ground, you will next want to check by connecting the red lead to your connector, and then connect the black one to the negative terminal on your battery.
What you should see is a reading of 0, if it is anything else, the stator is no longer good.
For your final check, you will need to change your multimeter to its AC voltage setting. Your large industrial engines will need to be running during this test. You should see an rpm of around 2000. You will also need to measure voltage tab to tab. The number here isn’t important, you just want all three numbers to be similar. If it is more than a few apart, the stator is faulty.
Estimating Your Stator Repair Costs
Depending on whether you want to purchase used or new parts, the cost to replace or repair a stator will vary. Variations are based on the cost of the parts and the time for labor.
If you would like to work with your existing stator, you can get an estimate for AC and DC stator services.
Some of the services that could be performed include:
- Welding the Stack
- Creating Spacers
- Duplicating Original Design
- Laser Cut Laminations
- Creating Flex Plates
