Mmmm, field controlled switches - love the glow :D

I just sold my Audio Research SP9 preamp which only had 2 tubes in it. I was shocked, I got more for the thing that what I paid for it 20 years ago!

Actually they are gas voltage regulators... The purple one is argon(I think), and is 150v, it's actually a bit more "pinkish" than the photo suggests... The orange one is neon and 75v... They are in series, so regulate a 225v voltage source...

battery is dead again so obviously it was a good idea that i did not run over the head unit like i wanted to.

I moved further up the circuit and put the little bulb in line with the pos battery post and the positive battery cable. 

with the key out and nothing on, the bulb lit up.

I unplugged the alternator output connector and the light went out.  perhaps it is the voltage regulator or alternator itself. 

Ill change that part and see what happens. 

Ill play the waiting game again with a new alternator and see how it goes.  The alternator is original but never gave me a sign of bad output.

Scott is that bulb the little #37 that is used in to light the switches and is also in the systems sentry???

its the bulb located at the thumb wheel adjustments for auto lamp/ auto lamp / headlamp switch.,, so yes is the answer to the question,, i think.

Yes they are #37... 

Drum Roll... And for the skinny...

They draw approx 82ma at 12.2v & 90ma at 14.4v... So if you know what to expect, can make a very good indicator... Also they take 25ma(1.7v) to light one so it can be seen in dark conditions and 40ma(3.5v) to be seen in average room light...

BTW I tried it on my TC and the light comes on bright, then fades out completely... Checking with a meter indicated a 20.2ma draw...

Yeah,, i had similair results.  The light will glow and when i unplug the alt, the light goes out.  I replug the alt back and the bulb "charges up" and then slightly discharges but remains on. 

Same results when i was pulling fuse 8,, I should have done the test at the battery in the first place.  I did not have a chance to purchase an alternator today but soon.

if this does not fix this problem,, then I will truely feel challenged.  Till now,, its been a pain in butt not to mention confussing.

My previous test showed the bulb went out when pulling fuse 8.  I have to look up that large yellow wire and its far end termination becaue it may have been tied to the radio in some manner. 

Its odd i unhook the alternator and it goes out as well as the radio.  Granted, the light bulb was positioned differently in both instances but still, something does not feel right.  I think i better look at the ignition circuit diagram of the ford bronco and double check the wiring layout.  I dont want to find out later that its something else. 

I did replace the ign switch down low on the steering column about 4 years ago (not the key switch) but for the life of me i cant remember why. 

Yeah,, i think i need to trottle back a little and study the path of that large yellow wire on the starter solenoid.  I suppose at this point it could only be the ign sw again or the alternator.  I suppose i could shot gun the porblem with both parts new.  I am getting pretty good at chasing my own tail on this problem so pop some pop corn.
