brain isn’t working diode

I'm trying to stock up on some diodes so I make sure I have them. I found a pack of 100 1 amp heavy duty 600v diodes (AT-D1-100 Diodes) and I want to make sure they will work for remote starters. I'm used to always using the 1N4001's but these seem to be the same.... just wanted to make sure since my brain doesn't seem to be working this morning.. hahaKenny

they will work, but i say 600v is excessive.Ted

50v is normal correct??? Thats where I was drawing the complete mind blank... lol Kenny

Equivalent to 1N4004, that's the most readily available, works on house voltages as well. Actually the shut down coil spike from a relay can be in excess of 300volts, let me assure you, I discovered that the hard way 40 years ago!

Yeah right Howie, like a relay could show you something the HARD way.

OK then more akin to shivering like a jelly (jello?) By the way and I'm sure it was you Craig you once posted how to show that, can you remember? If so please please post. Very funny unless you try it.

And I recall the above... And my recent reminder - the first in a few decades - manually grounding my car horn relay. (Broken slip-ring brush; used flying-clip.   Makes you wonder why they even need secondaries on ignition coils..) I am now very keen on a dash mounted horn button... temporarily of course!

I could not link to the post, so I copied and pasted. Is this it? Solder a red wire to terminal 86 of a relay. Solder a black wire to terminal 85 of the relay. Now hold your index finger on one terminal and your thumb on the other. Have a friend touch the other end of those wires to the respective terminals of your battery. Now have him remove and replace one of those wires. He may have to do it several times in a quick manner for you to get the full effect. The pain that you feel is the voltage spike that occurs anytime an electromagnet is turned off. As you could imagine that voltage spike is not liked by a lot of the electrical equipment in your vehicle. The diode eliminates this spike. It doesn't hurt real bad. Go ahead try it. No really it doesn't. It's only 12 volts how could it shock you?

That's the one Craig, thanks. I've pasted it to a word document, it's wonderful for teaching.
