Multimeter tests in electronics is a tool that allows you to measure voltage, current, and resistance in circuits or devices. Most multimeters have a range setting that determines the span of values the meter can measure for each function, and an on/off switch. A display, either digital or analog, shows the measured value. Many multimeters also include additional functions for specialized applications (temperature with a thermocouple probe, capacitance, inductance, connectivity to a computer, speaking the measurement, and continuity tests that emit a beep when a circuit has very low resistance).

Voltage, alternating and direct, is typically measured in volts. Most multimeters have ports designated COM (or -), mAVO, and 10A where you plug the black and red probes into to take measurements. The COM port is used for all measurements, the mAVO port is where you plug in the red probe to measure volts, resistance, and small current, and the 10A port is a specialty port for measuring large current.

Understanding Multimeter Tests in Electronics: A Beginner’s Guide

The squiggly line you may see next to or above a V or A on your multimeter indicates that it is set for alternating current voltage. The straight lines, on the other hand, are set for direct current.

Multimeters are commonly used for electrical repairs and troubleshooting at home, in automotive repair, and by hobbyists to assemble and test electronic devices like radios, computers, and TVs. They are also used in industrial settings to check the integrity of wiring and fuses. When a multimeter fails to provide readings, the problem often stems from incorrect or improper function and range selection, low battery power, or damaged lead wires.

Certified Outboard Motor RepairCertified Outboard Motor Repair

If you want to get the most out of your boating experience, you need a working, reliable engine. When your outboard isn’t running right, it can affect everything from the speed you can reach to how enjoyable your boating is. That’s why JBYS recommends contacting a certified outboard motor repair technician. They’ll have the expertise and access to specialized tools that aren’t available to the general public, and they can diagnose issues with your engine and make repairs or replacements as necessary.

Marine mechanics can install navigation equipment, troubleshoot misfiring engines and make other repairs to boats, including outboard motors. Many of these mechanics have received formal training from the manufacturer they work on, such as Mercury outboard engines, and they must pass a certification exam to be allowed to work on products covered by their manufacturers’ warranties.

Certified Outboard Motor Repair: Ensuring Compliance and Quality Standards

You should be able to find a certified outboard motor repair shop near you, especially if you live in an area that’s popular for boating. Look in local paper listings and ask friends for recommendations. Look for a shop that has manufacturer-certified technicians, such as Yamaha outboard mechanics or Honda outboard mechanics. You can also contact the manufacturer to ask for a recommendation.

In addition to outboard motor repair, a certified mechanic can perform other routine maintenance tasks, such as changing the oil and spark plugs, flushing the water pump, and installing new battery chargers. The best time to do these jobs is after every outing if you’re running in saltwater, and about every 2 or 3 outings if you’re in freshwater. This helps wash out salt, sand, silt, alkali, and other deposits and prevents corrosion and damage to the water pump impeller.

The Rise of Used EVs For SaleThe Rise of Used EVs For Sale

March 23, 2024March 23, 2024| darrylhumphreydarrylhumphrey| 0 Comment | 7:57 am

As the new-car market for battery electric vehicles (BEV) grows rapidly, more used models are entering secondhand car lots and making their way into consumer hands. While this is a welcome development, some consumers are wary of buying an older used EV because they worry about a battery that may lose range over time.

The concern is well-founded – BEV batteries are designed to last a decade or more, but they can degrade over time due to how the vehicle is driven and maintained. The good news is that even though used evs for sale are one of the most expensive parts of an EV, federal rules mandate that they’re covered by warranty for up to eight years or 100,000 miles.

Eco-Friendly Options: Used EVs for Sale

If you’re shopping for a used EV, chances are the batteries have a significant amount of life left in them. But finding out the exact state of a battery’s condition is tricky – the industry doesn’t have a standard set of metrics yet to measure battery health. Fortunately, a Seattle startup called Recurrent is working to change that with a free prediction service that predicts a used EV’s battery’s remaining range based on driving habits and other factors.

Another big benefit of purchasing a used EV is that buyers can get the same year-end IRA tax credit that new buyers receive. The exact details on how that process will work in 2024 aren’t out yet, but Recurrent will post updates as soon as they become clear. Qualified buyers will also be able to claim the NYS Drive Clean Rebate, which is worth up to $9,500 for certain models.
