Need help: Did my M4-ATX die?
Hi to everyone!
First of all: Sorry for my English, I come from Germany ;-)
I hope somebody can help me out with following (as I still hope I didnt blow my M4-ATX):
I just finishied building up my car-pc with a M4-ATX power supply.
I set it into P1 mode, connected it to GND, +12V, and IGN and connected the ATX-Cable from the car-pc.
Normally the LED then should start to blink, waiting for IGN, right?
But it doesnt... it just does nothing.
When I start IGN the LED should be on, but it isnt.
I measured wiring: GND to +12V: 12,8V, GND to IGN (when off): 0V, GND to IGN (when on): 12,6V.
So I disconnected all cables, waited for about 10 mins, switched the DIP to P0 (all DIPs off), connected it to GND and +12V (without IGN) and connected the ATX-Cable again.
The LED still does nothing. I also cant start the carpc with its powerbutton (which I directly connected to the mainboard to test P0 mode).
When I try to reset the M4 as described in the manual (disconnect, Jumper to P1, connect), the LED flashes for less than a sec, then does nothing. When I disonnect the M4 and take off the jumper P1, the LED flashes again and fades out then.
Does anybody have an idea how to do further tests to make sure the M4 is (or is not) broken?
At the moment I think it crashed...
Thanks in advance for any help!
