Provide voltage V+ which is voltage that stepper is rated at AND which can provide rated currrent. If yours is a digital multimeter, it will automatically 0 out on its own. After plugging the probes proceed and regulate them. It is annoying to spend much time and give a complete answer and then have do something else instead but SAY that they did what was asked. i cannot find even jerk in motor by doing so. Then do the same with B+. Your solution doesn't address the Original Poster's situation. Door panel screws (commonly 8mm, 10mm, T30, or phillips) Glass cleaner. First of all, check for the voltage with a voltmeter at the smaller control "S" terminal on the solenoid. By Electronic Multimeter While holding the probe on the first pin constantly, move the other probe across the other pins stepwise, each time noting the readings. in fact the stepper motor is like the synchronous motor it can run by the min ac power source. Lot of gates, lot of ICs, wires. Check that the brush springs still have enough tension to hold them securely to the commutator. If not, they could be skipping across high spots on the commutator. Place the test probes on the capacitor terminals, then make sure the resistance starts low and gradually increases. The first step is to include the library with #include <AccelStepper.h>. Do I need a thermal expansion tank if I already have a pressure tank? Two combinations should measure R ohms. (R an arbitrary value) Sometimes stepper motors get damaged causing the continuous electrical path to break. But I think it's possible to rotate it may be very small angle without a microcontroller. This is the process for Circuit Tester A. made a lot of test whis differe,t cable and more than then motors. Repeat A C A C. Motor should jump backwards and forwards a smal amount on each touch of A or C to ground with. I know this post is old but after reading with interest it brought back memory's I used to do something very similar to circuit above with the old brown door bell transformers which have a 4 Volt secondary tap which easily drives any 2 phase 4 wire stepper motor with added bananas that you can reverse as well as FWD the motor with a simple 2 way single pole switch. Use MathJax to format equations. "The article "How to check an electrical motor" refreshed my memory enough to be able to tell the supplier.
