While waiting for the wife to help me test the voltage and current going into the MAF sensor (using the jumper pigtail, a DC amp clamp, and a multimeter), I drew up a "revised" wiring plan.



I'm still undecided about whether to just get a step-down (Buck) converter, or for about the same price, or opt for a step-up, step-down (Buck-Boost) converter. The wiring I'd need to add would be the same, for either. Might as well get the more versatile unit.

If my experiment to reset and/or tune the MAF's output signal ends up as ineffective, then I can use the Buck-Boost Converter inside the house, as a cheap low-power DC power supply (I've got several old AC-DC power bricks leftover), to test DC devices and perhaps charge them. That is, if my experiment doesn't burn up the converter (and/or my test MAF), first.

My wife is back in town, but the outside temperature will be about 99-100F today, so my test must wait for cooler weather. She doesn't handle temps over 80F very well (she's had 2 trips to the emergency room, due to heat...though I've had many heat-strokes myself, I'm like the Energizer Bunny and I keep on going, though my DR. has warned me against it).
