Allows me to kick off the DPF regen before emissions test (thus prolonging the vehicle life and wallet contents) and kill the service indicator every time I don't get it serviced :-DD

med6573's one is a rather nicely engineered bit of kit though. I haven't cracked mine open but it's probably got bugger all in it.

On this side of the pond annual inspections, and what it entails, is left to each state to decide. California is the strictest state when it comes to emissions testing and there are some states that have no testing of either safety or emissions. I reside in New York State and we have an annual “Safety and Emissions Inspection”. The vehicle is checked for tires, brakes, steering, lights, etc. If the vehicle is 1996 or newer the ECU is linked on line to DMV (Dept of Motor Vehicles) and scanned for current and pending DTC's. If any are found it's an automatic fail. Even if it's DTC P0440 for loose fuel cap you fail. Get it fixed then test again (and pay again).

A few months ago the Honda Civic starting puking DTC P1457. The detail is “Evaporative check valve minor leak to atmosphere”. In other words....I had a small fuel vapor leak near the charcoal canister assembly. Horrors! I'm polluting! A bit of research revealed that this is a fairly common problem in older Hondas. The evap valve and the canister are located under the vehicle by the fuel tank, exposed to the elements. The evap valve rusts and develops pin hole leaks. And individuals reported that shops and dealers charged upwards of $500 USD to fix it. So a few weeks ago I got under the Civic and checked this valve. Sure enough, it was rusted. I ordered a new valve and canister assembly. About $150 USD in parts. 1.5 hours of my labor (cheap) and the new parts were installed. Reset the DTC and drove it for a week to make sure it was fixed. It was. Last Wednesday it passed it's annual inspection with no issues. That scan tool paid for itself again.

I spent a few years working in the AV Repair Shop in my High School; it was where I got my start in electronics. I've seen this particular failure mode more times than I can count in AA, C and D size battery holders of this type. Devices that get forgotten and stowed turned on tend to kill batteries such that they leak much more often; in extreme cases the resultant oxidation of the battery itself makes the battery "grow" in all directions. I've seen ones cracked apart like this where once you clean away the remains, you can see how the force of the decomposition of the battery was great enough to flatten the coil spring, and in some cases it stays flattened due to oxidation thinning and removing the temper of the remaining steel.

This seemed to be much more common with carbon-zinc batteries, however I have seen it happen with alkaline cells as well.

That is my best educated guess as to your culprit; not that it matters, because once the contacts are that far corroded, replacement really is the only option.

The fix I related earlier in this thread of cleaning with Windex & wire detail brush to neutralize the electrolyte and silicone dielectric grease to prevent corrosion relapse is really only reasonable in cases like remote controls and meters where replacing the battery contacts with new is not feasible.

GREAT find - thanks for the tip, bitseeker!   :-+ :-+ :-+

I just grabbed some.  There's probably a pallet of the damned things buried in a warehouse somewhere, and some day a space probe will find all those that have gone missing from old gear orbiting a distant planet in a huge clump, tangled up with the trillions of single socks that have vanished without a trace from washing machines and dryers down through the years.

Sure thing. I remember some of yours were missing the little guys. Looking forward to seeing them with their facelift.

Yeah, vanishing socks, pen caps, SMT components, etc.

It's the cleanest HP supply I've ever seen! They're usually in a right state  :-+

Looks like new! Wow!

Can you see the manufacturer and model of the power switch? I think it may be the same as on the HP 6114A. I got one that needs a replacement, but my good one uses a rocker switch, not flat toggle.

Specmaster:
Yes the batteries in this were I think Carbon Zinc as they were the original ones that came with the meter, made by Toshiba and were swollen and rusty.
