- 1Measure the voltages when the power supply is in operation (it's possible that the voltage(s) drop under load). If you suspect the power supply is faulty, you can replace it with nearly any IBM-PC type power supply you happen to have lying around (I've done this for my for Apple II, quickest way is 6 screw-terminals in the 6 wires. Make sure you connect the right wires.). If this doesn't help, next step is to get a schematic diagram and start measuring.dirkt– dirkt2016-07-17 11:09:18 +00:00Commented Jul 17, 2016 at 11:09

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. ms-dos), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
