Everything Needed To Fix Your 12v Wiring Problems!

**PARTS LIST IN DESCRIPTION BELOW** In this video, I demonstrate how to use continuity on a multimeter to diagnose and fix 12V DC automotive wiring problems. Start with setting the DVOM (digital volt ohm meter) to Ohms, and then find which wires are continuous and which wires are not. Common problems are: - Damaged wires - Loose connectors - Blown / popped fuses - Open circuits - Power & Grounds - Butt connectors - Damaged switches In general, this video covers diagnosis for race car wiring, alternator wiring, automotive wiring, how to wire a car, car wiring basics, wiring a car, fuse box wiring, hotrod wiring, and muscle car wiring. ➡ This is my video on how to choose the right fuse and wire sizes when building a circuit: https://www.youtube.com/watch?v=EhzN6UdnmPA ➡ Automotive Wiring How-To's: https://www.youtube.com/playlist?list=PLsF7T1tRFy2hmiiUUfMZNyV-BUA_yrPIh Items used in this race car circuit: 🔗 Ratty Muscle Car Amazon store - https://amzn.to/3KKkCdP 🔗 LED bulbs https://amzn.to/4dTTzs4 🔗 Clear shrink tubing - https://amzn.to/4d2XQZa 🔗 194 light bulb sockets https://amzn.to/3VQNPXr 🔗 Universal fuse holders https://amzn.to/3eVf2HN 🔗 LED Turn Signal Flasher https://amzn.to/3yW8vBx 🔗 Single Pole Single Throw (SPST) Switch https://amzn.to/4ghXuRd 🔗 100A Circuit Breaker https://amzn.to/3AQyqAq *As an Amazon associate I earn from qualifying purchases.
