RE: How to convert an ATX power supply to rc use
I tried to get this project under way but have a few snags...
The power supply is a 300w Astec Model SA302-3525 looks like 12v 12a output.
I cut all ends and grouped the wires:
yellow-post (currently wires are hanging out of the case)
Black-post (currently wires are hanging out of the case)
green-black
red-black to a 1157 bulb (no resister as of yet)
not using:
red
purple
white
gray
blue
orange
I have no switch just a plug and there is a voltage slider switch.
I plug it in and the fan turns and stops. I can dtach the green/black wire and retach the wires and the fan will start and stop for a second... from my read you did bring up that it could be a short but I do not see how in this case. Could it be due to not having a resister?
Any help? I usually get these things pretty easy... but not sure on this one.
