Doing something wrong... How do you use a multimeter?
Hi,
I'm working on my Defender, today, trying to get the wiring cleaned up and proper, detail stuff mostly (coin door lights, etc), and in tracking down the power to the coin lights, I was getting 9v dc on my meter(in DC mode, in AC, I got a solid 0v).
I'm racking my brains trying to understand how a 5v output on a switching supply can possibly give me 9v... Clearly I'm not using my meter right.
So with great embarassment, I ask for help, 'cos this is really driving me nuts! I've used 2 seperate meters on 2 seperate supplies in this game, and when I put the black probe on -5vdc and the red probe on +5vdc, I get 9v... What the *#%#???? It's not the dial, either, I can only get a variance of maybe 1.5v in either direction by tweaking with that.
Is there some funky thing with Defender, or am I just getting so old that I can't remember how to use a meter?
Thanks very much,
Ryan
