People always mention using noid lights to troubleshoot the FI. Looking around I see large sets of 6-10 different types, sets real mechanics might need to buy, but they are $30-50 for the set. We don't need all those variations, we need just one or two. Seems to me they should be available individually for ~$5 bucks.

Hello...Mikey?

Is there a different light for D-Jet and L-Jet or does the same light work on both? What are yall using? Are they available individually and if so, which one to get and where to buy?

Is a noid light overkill, or can a simple test light (the awl point screwdriver handle probe type) or DVM be made to work?

I could use the Bosch ones too but haven't seen it separately for less than half a whole set.

A DVM reacts too slow to read but will fluctuate letting you know it's being triggered, so technically yes.

Also, since injectors click, you could plug in a known working one and either listen or feel.

I bought a Harbor freight set for $12.
They work ok. It is just a bunch of different terminal types.
I don't think they pick up every pulse. Response seems inconsistent. I had a Subaru fi system that I wanted to check injector signal.

Saw these on ebay
