at 15K, the GP's should be pulled, and the holes reamed. also, the plugs themselves should have power applied and verify the TIP gets hot bright orange at a minimum.

If it wasnt so annoying to do it, Id say absolutely... It would make the engine easier to turn for the valve adjustment too.
Problem is it is nearly impossible to get the GPs disconnected and removed without pulling the injector spider, which means repriming and difficulty to start, etc., etc. Or am I blowing it out of proportion?

Finally we are on a subject that I actually am competent in. Another reason that the amps might be dropping (besides those mentioned) is the resistive co-efficient to temperature. Many heat elements (most) change resistance as the temperature changes. Some have a positive co-efficient -- resistance rises with temp and some have a negative co-efficient -- resistance drops with temps. This can easily be seen by measuring the resistance of an incandescent (quartz - for exampe) light. Using ohm's law and a cold resistance reading would not give anywhere near the amp draw that an ammeter would indicate. That's because the ammeter only measures the current as it flows (hence the filament is hot). Also ---- clamp type ammeters work well with AC; they barely function at all, and are wildly erratic, on DC. An in line ammeter with a healthy shunt is far more accurate than a clamp type.

I dont deny that it could be done more accurately, but even being 10A in 100 off is close enough to get a baseline for what draw truly is, and then to see if a GP is not working in the future...

less than a "Franklin".

I see nothing on that ad that says the meter will measure DC amps...

Mine is this and more than a Franklin:
http://www.fluke.com/Fluke/usen/Clamp-Meters/Fluke-336.htm?PID=70327 So Im pretty sure my measurement is OK.

Like everything else. Cant escape it. DO you know of a DC clamp meter that is US made?

searching, I found this page, it's interesting... and it states how accurate the fluke or other DC surround style ammeters are... it likes them, but gives tests for ways to use the less accurate style...
http://www.stuttgartperformanceengineering.com/inductiveammater.html I also found that amprobe brand test instruments are made in germany, not china... does that help? of course, they don't make any DC amp test inductive anyway...

As I have said before, testing with a meter will tell you that you have a problem, it will not tell you that the GP's are good as you can have perfect meter readings yet not a proper glow on the GP !! If one tests bad on the meter, then any one with any intelligence would know to test them all on a bench. Relying on meter readings is just a case of artificial intelligence ( the meter) being no match for natural stupidity (they guy who rely's on the reading)!! Many of us are rightfully critical of the limitations of the electronics that now 'controls' many cars, yet we jump to use an electronic device to test GP's. If your brushes are bad in your alt, you visually inspect them, same goes for GP's !!
