Opus 150W - input voltage drops to 2V
Heya, I've got this supposedly lovely lovely psu wired up to a 20A circuit in the car (ciggy lighter) the switched 12V down there is admittedly triggered by the headlights, not the ign, but I don't see how that would make a difference, 12v is 12v when all it's doing is activating the main circuit.
The second I hook the psu up to the feed, the voltage across the + and - leads falls to 0.5V and climbs back to around 2V over a second or two, then sits, like a sulky wet crappy dog that won't power my computer.
I get nothing at all from the PSU, no LED flashes, nada.... I can't find a short, and none of the fuses are blowing.
I am, to say the least, confused.
Any thoughts? The whole system works fine when powered from a psu in my house, and has also worked from the same feed circuit in the car using a 300W inverter and a normal psu.
