I think this diode is bad.
It meters .0L both ways. However there are no markings can anybody tell?

I am repairing an analog multi-meter. (attempting that is )

Thank you for the help!



here is another

It could be about any old glass-passivated diode. It's not big enough to be a rectifier. You can always try a 1N914 - good luck figuring where the cathode points.

It came out of the top right corner

Why cant you test components soldered in place if you just meter on opposite leads of the component?

What I was reading about electron flow, the positive and negative leads of the multimter would be the "circuit" right?

I went to two places to see if anything "looked" the same.

NO LUCK!

But I ended up buying a HAKKO FX-951 and an 808 desolderer.

This project is getting expensive.

I noticed the sensitivity of that meter was 2k/V. That's going to load down alot of the circuits you'll want to build ... and it could introduce some unwanted results to the circuit.

Thank you for the tip.

This more of a learning experiment. I have a nice Auto-Ranger.

I'm using this broken meter to teach myself all kinds of stuff.

Heck, I found my FIRST bad component--- All by my lonesome!

(with help from all the great reading on this site):D

Any cheap little signal diode is going to work. If you are concerned about voltage and current, consider the meter isn't much, and you're risking on the order of $.05.
