Title: Power problems
Post by: Jay on September 21, 2020, 10:52:25 PM
Can anyone help shed some light on this?
I've not been able to get a 9v readout on anything.

What I have tried:
Multimeter setting
(https://uploads.tapatalk-cdn.com/20200921/8064dd6c540d4481b7d4e12290933528.jpg)

Four different sets of leads
1 set with a brand new multimeter I ordered just in case mine was bad. (Same readings for both)

Measuring at the DC Jack:
Get around 4v at the pins.
Different jacks. Some tayda and some lumburg that I just ordered from lovemyswitches.com

A bunch of different power supplies.


Is there something I'm missing?
I get nearly nothing to any board that I have wired up including one I verified working prior to all this madness.

You are likely on AC.  I don't know that multimeter but you likely have to hit the SEL to change it from reading AC voltage to DC voltage when you select the V setting.

You need to switch to DC voltage. The wave in the display means you're measuring AC voltage. Look at the labels at the switch positions, there are two functions for each position. My guess would be you change the function with the orange button.

Took 9 months off and forgot how to use a multimeter. Thanks for answering my silly question.
