Great thread, thank you to all for their input. Craneman, your recommendation is on my list of tools to get when I return to the US. I see where this would be used often by me, both saving time and it's ability over just a multi meter. I am posting the following video as it shows where just a simple multimeter and knowledge would have saved this 24 year old drag car (Escalade, 2,000 HP) driver with his new to him rv some heartache (both time and $$$).
At 25 seconds in, he voices that he read on line a loss of power to the ECM often causes his failure. A voltmeter would have helped diagnose this issue. The first tech at 3:30 guesses that it is bad fuel pump. The second tech finds no power at ECM at 9:30 in to the video.
