Use diode 1N5400 or 1N5402 up to 1N4008 for 12V. All these diodes are rated for a 3 Amp rating. Diodes for such currents can have a significant voltage drop. The voltage drop in a tiny silicon diode working at its rated currents is approximately 0.6 to 0.7 volts. Other diode types have varying values—Schottky diodes can be rated at 0.2 V, germanium diodes at 0.25 to 0.3 V, … [Read more...] about What Diode to Use for 12V | In-Depth Guide
No Voltage Hot to Neutral but 120V Hot to Ground | Fact Behind That
You must measure either hot-ground or neutral-ground. Hot and neutral have been switched around if the neutral-ground voltage is around 120 V and the hot-ground voltage is a few volts or less. There should be some neutral-ground voltage when the system is under load; 2 V or slightly less is often acceptable. No Voltage Hot to Neutral but 120V Hot to Ground There can be … [Read more...] about No Voltage Hot to Neutral but 120V Hot to Ground | Fact Behind That
Why Do I Have Voltage When the Switch Is Off? | Fact Behind That
The phantom voltage or stray voltage can cause issues like detecting voltage even the switch is off. What Causes Voltage to Be Present When the Switch is Turned Off? You might notice that your multimeter is detecting voltage even though the switch is off. Due to stray voltage, it's capacitively coupled causing a voltage reading on a digital meter. But the ghost … [Read more...] about Why Do I Have Voltage When the Switch Is Off? | Fact Behind That
What is the Voltage Across the Capacitor Immediately After Switch s1 is Closed
The initial voltage across the capacitor is zero after switch s1 is closed. Before the switch closes, the capacitor's charge Q is zero and its voltage across the capacitor is equal to zero (V = Q/C = 0). The capacitor's charge has not had time to accumulate when the switch is closed, therefore the charge and voltage are still zero. After Switch S1 is Closed, What is … [Read more...] about What is the Voltage Across the Capacitor Immediately After Switch s1 is Closed
How to Test Onan Ignition Coil | Step-by-Step Guidance
To test your Onan ignition coil, simply disconnect the positive and negative wires from the coil. Now connect a jumper wire from the batt + to the + coil post, and another to a good ground. Tap the ground jumper on the negative coil post to test if the spark plug will spark. An ignition coil's purpose is to convert the low current from a car battery into sufficient power to … [Read more...] about How to Test Onan Ignition Coil | Step-by-Step Guidance
