WebSep 23, 2015 · Voltage. Voltage (V) is the potential energy of electricity. Voltage can be present even if there is no current flow. For example, your battery can have 12 volts in it even if it’s not being used. That 12 volts is … WebJul 23, 2024 · Check the maximum amp rating of your meter. Testing a 30-amp blower motor with a meter rated for 10-amps can quickly ruin your meter. The most basic tests you can perform with a DVOM are voltage readings and voltage drop tests. Here are the steps for a simple voltage drop test: Set the meter to DC volts. Often confusing and contradictory, electrical voltage drop symptoms vary according to the circuit’s job and the severity of the voltage drop. 1. Inoperative electrical parts 2. Sluggish, lazy electrical devices 3. Erratic, intermittent devices 4. Devices that work sluggishly or erratically during periods of high electrical loads 5. … See more Whenever an electrical problem gives you fits, take a deep breath and think of the basic electrical building block: the series circuit. No matter how complicated a system is, you can always simplify it to smaller series of … See more Excessive resistance on an electrical circuit can cause a restriction in current flow. Bad connections and broken or undersized wires act like a pipe with a kink, restricting current flow. Restricting current flow … See more Because ground circuit voltage drop can cause most of the symptoms listed earlier, consider adopting this new work habit: test grounds first. Before you do a tune-up, check out electrical problems, or test a starting, charging, … See more Electrical voltage drop varies according to current flow.
