measuring 24v on my onespot. Don't know much about switch mode PS.

Is that normal? Can you just hook up a MM to it to check the voltage? If that is the case mine is reading 24v, no good.

Edit: looks like it reads fine when I use the DC volts setting rather than the battery test setting. While I was looking for a problem in my rig I found a short in my CE-2.

I just measured a 9volt switchmode for my cordless phone and it read 18v

I guess that is normal

Phew! You had me scared there for a minute.

A properly working 1Spot always has about 9.1 to 9.4V on the output plug, whether it's loaded or not. Actually, there is an internal minimum load to ensure that it's stable even if there is no load on the outside. I have tested many of them by simply sticking a meter probe in the end of the plug and touching the barrel with the other probe. One that is not damaged will read in the normal range, and a damaged one will read either 0V all the time or "tick" up to about 9V then go off again. The ticking is the internal circuit trying to come up into normal operation, failing and shutting down to avoid damaging anything outside the unit.

Nothing is perfect, and nothing lasts forever. But I've been astounded at the low failure rate on 1Spots. I had the idea of testing returned ones to determine what was failing. Near as I could determine, the failures were randomly distributed in the parts inside and matched the expected infant mortality rates of the raw components themselves. You have to go to multiply-redundant backups to get much better than that.
