Fat chance Roy. It's having a grand soireé together with my wallet. I have my scope tied up in 3 trash bags along with a 1 Kg jar of silica gel. I would love to find a bargain on a 5 MHz scope meter.......but...
I would love to try and discover why MoPar thinks a nervous .4vdc hunting is truly necessary on their ECU alternator voltage regulator circuit. Actually a one-minute span reveals an almost 1.0 volt wandering. The dash voltmeter has so much damping it reminds me of a fuel gauge. I love it when I start the toad on a 100F day and for a few seconds I see "15.04" on a DMM. But the nightmare seems to be bullet-proof other than for sheer stupidity of locating the ECU beneath the battery. When I take the toad back to Michoacán a field strip-down, parting of the plug and socket and dosing with D100 will be in order. Then comes an array of TVS devices. Good old oscilloscopes a viewport into The Dark Side.
