Did you hook up any external LED Lights? Do you have any thing plug into the cigarette lighter\Power Port. Any USB Devices for car audio? Fully disconnect the batter and hook up a multimeter to see if anything is drawing power

Alright guys its followup time. I had to leave town shortly after discovering this issue Friday and got home this afternoon to check it out. Went to crawl space no chewed wires. Opened hatch on condenser started poking around with my multimeter aimlessly. 1/2

How Does a Digital Multimeter Work? - Understand the Essentials. Have you ever wondered what’s actually happening inside your Digital Multimeter (DMM) when you probe a circuit? While it looks like a simple digital screen replacing an old analogue needle, the "magic" inside is a fascinating process of high-speed translation. Based on the expert insights from Electronics Notes, here is a breakdown of how your DMM actually works: 1. The Core: The ADC (Analog-to-Digital Converter) The heart of every DMM is the ADC. Most general-purpose multimeters use a Successive Approximation Register (SAR). • Think of it like a game of "Higher or Lower." • The ADC compares the input voltage to a reference voltage, starting at half-scale and narrowing it down bit-by-bit until it "homes in" on the exact value. 2. Signal Pre-Conditioning The ADC can only handle a specific, small range of voltage. To measure different things, the DMM "prepares" the signal: • Voltage: Uses potential divider networks to scale high voltages down to a range the ADC can handle. • Current: Measures the voltage drop across a known internal resistor (a shunt) and then calculates the current using Ohm’s Law. • Resistance: Passes a small, known current through the component and measures the resulting voltage drop. 3. Buffering and Averaging Ever notice why the numbers don’t jump around frantically? The DMM doesn't just show one raw sample. It buffers and averages multiple samples to filter out electrical noise, ensuring the reading you see on the LCD is stable and accurate. 4. The "Settling Time" Factor When you switch ranges or probes, the internal circuitry needs time to stabilize. This is why the reading might "climb" for a split second before staying still. High-end meters also perform an Auto-Zero to ensure there’s no offset error before giving you the final result. Pro Tip: Understanding this process helps you realize why "settling time" matters—especially when using computer-controlled test equipment where timing is everything! 🔗 For a full explanation, check the link to my website in the comments. #Electronics #Engineering #TestEquipment #DigitalMultimeter #EmbeddedSystems #LearningElectronics #electronicsnotes

The money a good multimeter and knowing how to use it saves you is insane.

For insulation resistance test, you need a megger tester, I understand some recent flukes multimeter have that capacity

Me in the dead of winter when gas boiler went out and HVAC companies were swamped. Thanks to Claude and a multimeter, found out it was thermal cutoff (STC5257). $4 part. Supplyhouse(.com) had it to me next day because local ones don't seem to deal directly with consumers.

“Two bread boards, a couple wires and a multimeter”

Multimeter. The capacitor is rated for a capacitance of 30uF. It read 5.26nF - effectively dead.

Look what just arrived! Wallet-type pocket multimeter from @eevblog Thank you Dave!

Loads of people are self-employed, or have a small business. They then receive not only the wages for their labour, but also the interest for their capital (e.g. spanner for a plumber, multimeter for an electrician), and the profit for their entrepreneurship.

i haven't had the balls to turn it on yet. and have been too lazy to plug it in and get multimeter readings

My HVAC was not turning on a month or so ago. Before I called the HVAC guy I went and bought a multimeter and tested things myself. Found out it was a faulty switch on the condenser drain line. Swapped it out and back in business. Feels good to DIY stuff!

My favorite is when my wife puts something "where it goes" and I get to guess why a multimeter "goes" in the utensil drawer in the kitchen

Great job man, with AI, YouTube, some simple hand tools and a brain, most home repairs are possible and easy. Good job having a multimeter. I recommend everyone to have one. I'm a tenant and ended up replacing my own cartridge on my water tap for the same reason. Landlord said most companies were 1-2 weeks wait. Ain't nobody got time for that. I need water in my bathroom sink.
