If you look at the RB30 circuit the globe is in circuit with the field.
If the globe blows the globe doesn't work, and
If the globe blows the Alternator doesn't work as it probably won't flash unless there is sufficient residual magnetism, and lastly
If the globe blows you have no warning the Alternator doesn't work
Ergo, if it is blown nothing works.
Is this better??!!
Why didn't you say so before? I would've corrected it ages ago.
I know the wording was incorrect.
What I am saying is that the alt warning globe is actually an integral component of the voltage regulator circuitry. if it blows, due to age, vibration, over voltage etc, the alternator will not work. Therefore, if your alternator is not working, checking if the globe is blown is one of the first and easiest things to look at.
Always replace it with a similar wattage globe as it will affect the operation of the regulator.
It wasn't a thread hijack. You brought up something pretty damn important.
You did a big favour to me by bringing it up. I didn't even know before that I should've asked that question.
Now, I do.
The idea that the failure of alternator warning light leads to alternator failure is something totally new to me.
Now, I just need to understand it along with my OP questions.

Yeah, I think it's a bad design. The regulator should be "smart" enough to have separate warning lamp circuit & field current circuit, as it may be indicated in the below picture. L & IG are two separate pins/wires that come out of the regulator in the diagram.
But, apparently that's not the case with RB30 alternator regulator?!!

Why? .
Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.
sense wire have connection issues or the fuse on it dies and the alternator puts out some 18+ volts.
That kills the alternator dash warning light(assumption on my part).
Now you have a sense wire problem and warning light problem, a combined trauma.
Auto sparky is the only guy who can figure that out.
Certainly it won't be my cup of tea, regardless of how much I've learnt from you guys.
