I suspect the neighbors are not asshole; they are crazy.

give that judge a medal.. he’s cured a bad case of harpies.

I had to scroll way too far down for this. The 24v you don’t feel unless your skin is wet or broken. The inductance ‘kickback’ from a solenoid - or even worse a big starter motor, will give you a very nasty jolt. I was fooling around with a 24v 10a scooter motor. It gave me a big shock when i interrupted the 24v…

I’m quite thrilled with my result. I’m in the market for one.

I don’t think it’s just the cold. It’s the constant shift between extreme cold and high heat- the rapid expansion and contraction on those plastic parts will accelerate the brittle-ness.

You caught most of them but there are other aspects like lot to lot material variation which don’t get caught in internal testing or OE PPAP.

Don’t just test random parts, understand the output from your process be it the range of plastic density, color mix, raw material supplier, regrind percentage ect ect then test…

I worked for a major brake OE, I know all about these type of test stands. I wrote a designed a massive internal study which proved that your wild temp swings on the dyno do not actually simulate real world conditions. There’s problems with plastic aging especially that you won’t see on one of these test stands.

I know…

Or a Porsche where the battery is in the frunk, which open at the touch of a button near the driver seat, a solenoid activate the frunk locking mechanism. Which means that if/when the battery dies, you can’t access the battery ...

I proactively replace junk like those plastic clamps. The get brittle and age poorly with all the heating and cooling cycles. They are meant as a cost savings measure. Oh, for the manufacturer, no me.

Tested by some guy in an environmental chamber, not in the real world. Or even worse that’s just the engineering spec for the material without real world testing. After working with/for OEs in materials testing labs nothing surprises me anymore.

The problem I’ve seen with plastic crap failing on my vehicles has been age. Plastic just doesn’t age well and seems to get brittle - you might be onto something with the cold/vibration combination on startup. 

ah, being in Canada can be a problem sometimes.

Some years, it can get a lot colder than that, depending on certain conditions. Also, does that take vibration into account, using a cold start as an example??

So you’re “that guy” manufacturing the magic bullets that everyone else hates and you have no idea why. Just an FYI. Stainless crimp clamps FTW

We’re gonna ignore that I’ve worked for Freightliner, and this isn’t the only sketchy design decision I’ve seen from them.

This is a Nope gif waiting to happen.

That “cute” 0-60 time will embarrass all but the La Ferrari

Ah yes, Maserati, all the maintenance costs of the Ferrari without the performance. Sounds awesome. (Please sell me literally any Porsche for less money).

Yes and no, I think. The military spends billions on jets and ships like they’re going to fight another modern army or an alien invasion. But the ultra expensive tools of war are completely inept at taking on the potential threat highlighted here. This can be used as an argument that we need smaller more personal…
