Did I fry my istD?

[Toine Kuiper]

Today my istD was repaired by Pentax. The flash charging circuit board
was replaced. It was repaired very nicely by Pentax.
The internal flash died and caused some short circuit (the battery
indicator showed zero and everything stop working)
Now I'm wondering if I fried my D with a Metz CL1??? I don't dare
connecting it again. The specs and measured voltage are ok I think.
