Europa-List: Panel Testing

[mike gamble <mp.gamble@tiscali.co.uk>]

Checking my panel on the bench  before installation. 
Powered up with 12V and before switching off in a panic, I observed a 
rise on the voltmeter which I expected but also a rise on the fuel 
gauge, the oil pressure and at least one of the temp gauges .
What should I expect the standard rotax engine instruments to read if 
their sensors are not connected? Have I wrecked them already?
Reassurance needed.
Thanks
