    What was your earliest national/international memory?

    The death of Winston Churchill in 1965. I was nine and a half and was annoyed that TV programming was pre-empted on BOTH channels, ITV and BBC.

    If you remember pounds, shillings and pence.

    Oil

    If it's that important you might want to use the correct number. Six pounds/gal is typically used for gasoline. Oil is typically figured at 7.5lbs/gal or rounded up to 8...

    Oil

    Why do people talk about the weight of oil? The correct term is viscosity. I figure it's sheer laziness; one syllable is easier than four. And by the way, the "W" in 20W-50 does not stand for "weight"; it stands for "winter". Now get off my lawn!

    Cessna hacks

    Why would one need to manually cover the pitot when Cessna has provided an automatic metal one?

    When to replace/overhaul alternator?

    Agree with Dan that the alternator doesn't produce any current during cranking. However what you say is relevant when giving someone a jump from your automobile. If the good one's engine is running while the bad one is cranked it will stress the good alternator. In addition to the high...

    When to replace/overhaul alternator?

    Yeah, many motorcycles also use a PM alternator. Problem is you have to regulate the output directly with zener diodes or SCRs etc. instead of regulating the lower current field winding so it's only practical for 20A or less. What Dan is referring to is a much fancier system which essentially...

    When to replace/overhaul alternator?

    That's a whole lot shorter life than what I've seen in automobiles. Worst case for me was 60,000 miles in my '85 Astro. Back then you could still buy brushes from the dealer so I did. Found one brush severely worn. The other one was missing, so it likely wore enough that it fell out of the...

    Radio Static when Receiving. Progressively worse through the flight

    If your headphone and mic plugs are brass, I suggest polishing them with crocus cloth or fine emery paper, them wiping with a rag and contact cleaner. This will remove corrosion.

    "Screw Yourself" Public Service Announcement

    I'm guessing your RV coachwork is full of those. Canadian built furniture likes to use them too.

    HVAC guys are cool............get it???

    Does your thermostat have a "fan only" position that makes the fan run all the time even when there is no cooling or heating? If so I would use that to simplify things when troubleshooting the fan. No worries about things freezing up etc.

    Non Impulse Magento QOD

    The older (pre-1976) automobile ignition is often called battery ignition. Both it and a magneto have points and a coil. The difference is how the coil primary is "charged" with current. With battery ignition, when the points are closed, current from the battery flows through the coil. In a...

    Non Impulse Magento QOD

    Considering the fact that the breaker points are grounding and ungrounding the primary winding dozens of times per second during normal operation, it seems highly unlikely that an errant ground from the P-lead would do any damage. OTOH, a defective ignition switch could conceivably connect the...

    Constant Amp Discharge with Steady Voltage

    I suggest you connect a temporary second ammeter to double check the JPI.

    Brake job cost?

    One hypothesis is that more recent cars have less meat on the rotors than older ones, thus reducing the possibility of turning them. Supposedly it is done to reduce weight and get 0.001mpg better. I replaced a rotor on my wife's car recently and measured the new rotor thickness. It was only...

    White lettering in or out?

    YGBSM! I was personally affected by the Firestone 500s on my wife's car in the late '70s. Every one of them self-destructed. The replacement 721s were not much better. Then there was the Ford Bronco/Firestone scandal in the late '90s...
