Why do you think that is so? There are reasons why what you say is absolutely correct and, if true here, would help explain Martin's experience and potential for a future repeat. Some vehicle OEM wiring is aluminum. Much of the grid is built with aluminum wire. This is done intentionally and...

Glad you figured it out. Nothing wrong with a fuse in the negative. Like I say some accessory harnesses come with them and it's an extra layer to prevent excessive fault current on a negative run like may have happened to you. Some nuisance downsides, like now you have more fuses to check and...

Yes! That's exactly the sort of thing you're looking for, it make sense. I'd guess the way and length of insulation that melted that the cable got hot. Are you sure of the size and loads it carries? One reason this can happen is it's carrying a load you don't expect, too. You know how the...

No, it doesn't necessarily indicate the charger. I did a poor job of explaining. What I'm suggesting is that the voltage drop could increase with load. When you first turn on the DC-DC it's a low draw, just the internal consumption, a few watts perhaps. This is the power the device itself...

recreation.gov is run by Booz-Allen-Hamilton. https://pmags.com/the-scourge-of-rec-dot-gov Who, I'm not sure incidentally, was sued over just where the fees go. https://web.archive.org/web/20230607024751/https://www.tzlegal.com/recreation-gov-fee-investigation/ The whole process is a scam, a...

Try measuring the resistance of the input on the DC-DC, both polarities. If your meter does it I'd also check the input using the diode check function, also both polarities. What you're showing looks odd and what I'm asking is to eliminate that it's the DC-DC. It's possible the DC-DC did...

Regards to made in USA or perhaps just not made in China. There have been such radios in the past but current production isn't really going to be an option. You might get not Chinese made but I'm not sure there's ever been a US-made GMRS/FRS. I'm not sure there's even been a US-made FM mobile...

An alternator will have a continuous rating and a peak or absolute maximum. I don't know yours specifically but typically medium, heavy duty, marine type Denso, Balmar and similar fall around 80°C to 90°C for continuous and might tolerate 105°C or so. For a light duty I would expect 93°C/200°F...

It's not a simple yes/no. You're right that multiple chargers can and often do run in parallel. The problem is coordination. You have multiple control loops running and there's no guarantee they'll operate well together. This is more of a problem you'd have with smart or multi-stage...

Not an influencer but I run a DIY battery box. I had some of the components already so if starting from scratch I might have made a few different choices. It has come together over time as I change things, experiment, etc. Having commercial off-the-shelf devices can be handy with apps and...

This piece of advice needs to be clarified. If you're fusing for a 50A circuit you use a 50A. Fuses are sized based on the current they will hold indefinitely. They will open at some current higher than their rating, which is going to be based on a time-current curve. So the higher above...

That's the bike industry in a sentence. You could have also said "the manufacturers love to convince everyone that they are Matteo Jorgenson."

Dylan Johnson did a great video on this. It's hard to really believe how back in the day we were running slammed mile long negative rise stems and rock hard skinny tires and all that. We thought we were fast but really smooth is fast.

FWIW in case anyone's interested. This is my all around mixed surface and gravel all cleaned up for spring. On the fatter side at the moment coming off winter, 29x2.2 front and rear, so technically 700x55. The frame is the tail end of what I'd call the classic MTB frames, 2012 Gunnar Rock...

Unistrut is happy to send you an engineering catalog that tells you everything you need to know. They know it's used for all sorts of things other than just hanging conduit and pipe from ceilings. It's completely fine to use for racks like this. https://unistrutohio.com/pages/unistrut-catalog...
