Hi,
I have disassembled an old furnace of mine to get some parts back for a project. I scavenged a 8LED display. When I tested the pins, it did something odd. The tested leds kept blinking in and out (As if they had a really slow PWM on them). I've never seen this before. Any explanations/ideas on what it could be?
I ran my test :
12VDC, limited at 20mA.
At 5VDC it was working, but the light was dim and the power supply was giving 12VDC to the transistor.
Attached is a picture with the piece. I did my research online with no luck.
Thank you,
Jeremy
