    Power supply not working

    So during our meet today, my computer stops working. Couldn't figure out what the problem was at the time, so I gave up.

    Get it home, test a few things, and it appears that when I connect +12 to the PS (Keypower), the voltage drops to +3 to +4 Volts! No fuses are blowing.

    Anyone care to take a guess at what could be causing this? Internal shorts? I've unplugged the motherboard and as many accessories as I could easily disconnect. Same results. This is direct to the battery (through a switch and fuse both rated at 30A) - SDC and other things have been disconnected.

    The Keypower is ~5yrs old, so I suppose it's had it's time - I also just added a GPS and it was acting flaky last night - kept shutting down.

    Found it. Faulty relay.
    So, let that be a learning experience for me - if power faulters when under load - check that the power and ground lines work! (phew)
