Use an ammetervoltage meter to test the starters current draw. Your next question would be something along how to.
Disconnect starter lead assuming that frame is GND MM black to frame MM red to leadred test start key.
Starter draw test with multimeter. Testing the resistance of the starter with a multimeter is a fundamental step in diagnosing vehicle charging system problems. A starter that shows high resistance will drain power from the battery faster than the alternator can recharge it. A basic device is all youd need for a parasitic draw test with a multimeter.
Just make sure it can test amperage has an auto ranging mode and is at least a known brand. US brand INNOVA makes decent multimeters for automotive tasks such as the 3340 or cheaper 3320 but even a standard electricians multimeter can do the trick. Test the batterys voltage with a multimeter.
Set your multimeter to its DC setting and its dial to 20 to test from 0-20 volts. Place the red probe on the batterys positive. Dont worry about your multi-meter.
If its not cheapo its got protection circuitry. Disconnect starter lead assuming that frame is GND MM black to frame MM red to leadred test start key. Use an electrical systems tester or an appropriate clamp-on ammetervoltage meter to troubleshoot a slow start or no start condition.
This test requires the specifications for the vehicle being tested. Set the voltage meter to measure battery voltage 126V. Disable the fuel or ignition so the engine will not start during the test.
Use an ammetervoltage meter to test the starters current draw. Connect the test leads to the positive and negative terminals and then connect the clamp-on amp pickup around one of the battery cables. Set the voltage meter to Int 18V and adjust the ammeter to read zero.
Disable the fuel or ignition to prevent the engine from starting during the test. Measuring Ohms for Starter motor. Thats all it takes to cause cranking problems because of the high current draw.
Aside from all that crankno start problems are often caused by other things like lack of fuel andor ignition. Engine and frame grounds. This testing should be done by looking at voltage drop under.
This video shows how to perform basic current draw test using a security system as an example. The batterys condition is the most important part of the starter tests and the first thing that has to be checked. There are two parts to this test.
Visually checking that the battery terminals for obvious problems and testing the batterys voltage with a. Such test takes the particular car engine current draw outside of the starter and ambient temperature into consideration as the current draw to start a 4 cylinder car is vastly different from a big diesel toaster tester focus only on the battery and not the entire system as. This video will show you how to use a multimeter to check volts going from the battery to the starter and use an amp meter dont use the multimeter for this part to check the amps at the starter.
The starter on your cars health is directly related to how many amps it pulls from the battery. Lets interpret your voltage drop multimeter test. Your multimeter registered 09 Volts or less.
This is good and a clear indication that the starter motors ground does not have any issues. Your next test step is to go. Turning The Engine By Hand.
Your multimeter registered 1 to 7 Volts. This is a bad test result. The multimeter is a troubleshooting device that can be used to check for voltage current and resistance in an electronic system.
To perform the test your solenoid you would have to involve the multimeter. Your next question would be something along how to. How To Perform a Battery Parasitic Draw Test - YouTube.
The Digital Multimeter is equipped with two fuses to prevent damage to the meter in the event that the input limits are exceeded. If the meter displays a reading of 000 when testing 12 volt starter motor current draw or DC amperage output check fuses in meter. Refer to FLUKE Operators Manual for procedure for checking fuse.
If you are looking to test for amperage draw parasitic draw testing amps in series we cover that process in this guide. Other than trying to start the engine to see if theres charge the best way to decipher a car batterys status is to test it using a multimeter. To check the starter you will need the energy from the motorcycle battery.
If you run the starter solely the multi-meter will have nothing to connect with and you wont be able to measure anythingSo remove the battery from your vehicle and charge it before doing anything. The starter motor I worked on passed the test as it was above the minimum voltage requirement and was within amp draw specification. After the starter had been stripped down visual checks were done to see whether any damage had been done to the motor that might require replacement first to be checked was the armature the visual checks that were done.
