[Shop-talk] noid light

[Eric J Russell]

I have a dead cylinder on our Alfa Romeo GTV6. Spark plugs are good (swapping
them does not change the location of the dead cylinder), plug wires are good
(normal resistance and I can get a good fat spark by holding the end 1/4" from
the block)

I want to check for electrical signal to the fuel injector. Can I use a
digital voltmeter to test? (Start engine, remove connector and put the
voltmeter's probes on the two contacts. I have a wire diagram to tell me which
wire is + & - )

I don't have a noid light. Is that an LED or some special light bulb?
