Lightbulb moment

[JOEPRO]

Of all the automotive electrical test equipment I have, something simple is sometimes best!

I wanted to quickly confirm what fuse in the car powered a circuit I was working on. So I need an in line test light. Surprisingly there are very few items like this on the usual sites. At least for a fair price.

So - I cut a cheapie bannana lead and soldered it to a 12v orange indicator bulb. With a croc clip one end and bannana plug on the other I can back probe, pierce or clip the other end.



Really easy, fast fuse confirmation. Just pull fuses until the bulb goes out.

This will prove very useful.

Some other uses - as it can be left connected unlike other test lamps I can connect to one end of a circuit and use a power probe to send power to see if the orange bulb lights up



I may make a couple more but with higher wattage bulbs for load testing circuits.

I use one of these, indispensable.
I did throw away the cap and replaced the weedy pointer with a panel pin.

Yes I have a couple of those type of testers.

The one I made up differs in that it can be conected both ends and viewed / operated remotely. Which is much more useful for joe no mates like me!

Gosh. That looks really similar to one I had back in the 70’s. It did the job perfectly.

That cannot be true. You must know at least Climate, Animate, Primate, and sadly Cremate.
