Terminator 2 - Testing power supply? (Noob questions)
I have a Termnator 2 which wont boot up. So I am thinking first thing lets check out the power supply.
Symptom: contstantly reboots. Even gets to some type of check screen than reboots. Garbage constantly comes onto the screen as well.
Getting out my multimeter I am wondering if I am doing this correctly.
First off the multimeter should be DC, so I set it to that. See the picture of how I have the multimeter setup (ignore the reading though as I had nothing connected) Which I think I have that part correct, and the cables plugged in correctly.
Now here is where I dont get it. In my head I am thinking I need a - and + to check the voltage coming out the device. I checked the AC from the wall and see 122ish, and that made sense because the only inputs were side by side, but the DC ones are all over the place.
See the picture but it appears to me that going from the AC inputs you have:
(+12V) (EmptyPin) (-5V) (Two pins-+12V) (5 pins ground) (Two pins +5V)
Okay in my brain I am expecting a - and a + somewhere like you would see in a car battery, but that isnt true here. So am I to assume that where I stated Two pins, one is + and one - ?
From what I could tell the Two pins +5V were showing about 4.98V DC, but the two 12V pins were not showing that and fluxuated. Now keep in mind I am not sure I setup the multimeter correct.
What are the pins which are on their own with +12V and -5V for? From what I can tell though neither are used.
Now look at the power supply with the connector hooked up. Why is the connector longer than the power supply? One pin which has a wire in it, doesnt even connect. Surely that is not correct?
So I am wondering what I am doing wrong here. Obviously I am a newbie and I expected to see + and - signs and be able to just easily grab voltages, but this is not showing what I thought it would and the marking I expected to see are not present.
Just want to make sure the power supply is correct before I move onto the next task of breaking down the board and figuring out whats wrong there.
