help, I blew something big

Always fit replacement fuses upside down, easier for fault finding later when you forgot what you have done already.

Now I am even more suprised anything works on Bacho86 truck... at least 1/2 his shit has shorted out at some point.

(Sorry, Graham, couldn't resist)

Does it matter which way fuses are installed? (Too early in the morning to tell if you're pulling my leg ... Lol)

First time I'd open that hatch that housed all the fuses l, pretty sure they were all like that already though...

Just use this method to work out if you're being had...

Is the post by ET?
No - further investigations required
Yes - the post is full of sarcasm

... hurt most deeply am I by that

Now, I'm dying to find out how you managed to post the upside down smiley.

Does it matter which way fuses are installed? .

AC fuses - No it doesn't as the current flows one way 1/2 the time and the other way for the other 1/2.

DC fuses - Yes, the +ve is the larger leg (just like the +ve terminal on a battery is larger than the -ve)

In a DC circuit the voltage drop in the wiring mean there is less arriving at the -ve terminal

That takes us back to Winnie's method in post #23 lol

Well I thought it was appropriate given the topic... Upside down Smiley face is a standard option on iPhone

This is a common mistake that comes about because it was thought that electricity flowed from positive to negative. We now know that it is actually electrons flowing from negative to positive. The positive terminal still has to be the larger one to catch all the loose electrons.
You can test this theory yourself, the nozzle on the end of the garden hose is about 1/4'' diameter where the water comes out, but you need a much bigger area to catch the water that has come out.

If you are using AC fuses on a DC circuit you should take them out and reverse them once a week.
