If there is no voltage, there is a break in the circuit between the battery and the + terminal. Possibly the ballast resistor is faulty. Checking the coil To check the coil, wedge the points open and connect a voltmeter between the negative - terminal of the coil and earth. ...
Next grind down the portion of rib that is glued to the baseplate so that it will form a sloped line going from the ½” tall height of the rib to the center ¼” tall strip (editor’s note: its easier to layout the rib patterns with this slope in mind and save the grinding)....
Change the 470Ω resistor to 1kΩ resistor. Change the 12v zenner diode to 15v zenner diode. Increase the number of windings on your flyback transformer. Increase the value of the inductor. This should work well for voltages up to 60v before the MOSFET's should be changed as well... I...
Older vehicles with points-and-distributor ignition may have a third wire to the coil, bypassing the ballast resistor. Don't get them confused. Now get a socket and ratchet and probably an extension, and remove the bolts holding the starter to the block. You may also need to remove a ...
I wouldn't use the output of a class D amp as input for another amp since class D amps got a high THD. But you could try it to check if it would be ok for you, it's not a HiFi application :-) Add a voltage divider (output about 0.5-1V) and a small pass capacitor....
it needs a chiller and a high amperage constant current driver with no voltage spiking or current overshoot at all, as laser diodes and laser diode array modules are very sensitive beasts that run away without current limiting and soft start., A ballast resistor just isn't good enough to dri...
Check Fuses A blown fuse can be annoying, but it actually helps prevent electrical damage and fire. Fortunately, fuses are inexpensive and easy to replace. If the power’s out in your home or car, you should be able to check the fu... ...
