DIY: Cost effective car fuse tester

bravo82in · 10th January 2025, 21:01

When my car voltage tester failed early in the morning (right as I was trying to hardwire a dash cam), I needed a quick and cost-effective solution without waiting for the market to open or an online delivery. So, I came up with this simple DIY fuse tester, which worked perfectly.

I used an unbranded car interior LED light I already had, extended its wires, and made a few tweaks. The negative wire was looped through a hole in a cloth clip, and the positive wire was attached to a safety pin.

In just 10 minutes, and at a total cost of Rs 50, I had a functional fuse tester.

Please if you can elaborate how you used this to test fuse.
I used this coin type led recently to replace the festoon bulb in my Zen’s cabin light. It’s much brighter than the original festoon bulb which also goes dim after a few days. Costs super cheap at Rs. 10 each. I even put one additional lamp in the boot and wired it through a door switch activated by the tail gate.
