Jeepers Creepers, this is why Design Engineers need PRACTICAL Engineers to over see them
When I first brought this up, GRJ said it was too hard and too costly, so get an Oscilloscope. NOW, Adrian designs what I asked for about $10, and all of a sudden GRJ is asking for upgrades for it!!!!
So let me add some practical advice. Certainly a go no go is ok and I certainly would pay $40 for one that can easily test a TIU output. Show a perfect signal around 12V with Green, Show and acceptable around 9V with Blue and a Red for no go.
If there is a crude adjustment POT that can be calibrated in rough voltages to get a green to light up at the set value 3, 6, 9, or 12 that would be great, and no other LED required. Start at 12V, no go, set to 9 and retest, still no go, set to 6V and if it lights up, you have a rough estimate. But frankly if less then about 9V from what I have been reading and you should replace the Transmit chip. So a simple device and I do not see how Service techs would not pay $40 for the test equipment. We far more for a PS-3 Test set. BUT we need something that doesn't take up square yards on the work bench, so for me a O Scope is out. This device is in. Thank you for this effort. ADRIAN if you build me one I will pay for it and then pass the charge on to MTH G
