Hi Guys,
I'm trying to complete the pre-power checkout on my just assembled Excalibur.
I show no shorts to ground on atlas +12V or +5V. For the +6V test point I
have about 2.4K to ground (OK). For the +5V test point I show 15.1K to ground
versus 4.1K expected. For the +3.3V test point I show 111.9K to ground (sort
of close). I re-checked these with both the lower pin of J3 and the shield of
the lower BNC. I also tried a second meter.
Any advice you can give with respect to these anomalies would be appreciated.
I haven't tried a "smoke test" yet.
