Smoking Resistors | O Gauge Railroading On Line Forum

Pat CoilOGR Forum Member

Hooked up 12V DC 1A power supply to LED flood lights (3V) using resistors supplied from vendor. Yikes smoking resistors, too hot to touch! Now what do I do. Anybody know an English speaking supplier who can talk me through this?

It would be useful to know what resistors and LED's you have. Clearly, either the resistors are rated incorrectly for what you're doing, but without any details, hard to know.

Also let us know if you have a meter that measures voltage and resistance/ohms.

Try using another resister in pallial.

Also you need to found the resister rating.

Check to make sure you have it wired properly and no touching wires
