I'm currently putting together a CK2III using all the recommended parts. I'm nearly done but I do have a few questions. I've put together a cmoy before so I do have some experience but I am in no way experienced at diy electronics.
1. Me being smart, decided to see what color the led was by hooking it up to a 9v battery which immediately blew out the led. Is an led mandatory? or can it just be bridged with a lead? Also, I can't find any information on the orientation of the led on the board. Which way should the led be hooked up to the board?
2. I've hooked up the primary leads of the transformers but the secondary leads are giving me a bit of trouble. As of now, I have the wire with the voltage through it going to the positive or square pad on the board. Is that correct?
Sorry if the wording is a bit confusing, I can take pictures later if it would help. Thanks
