What orientation was the sensor in the collector? i.e. was it at 3 o'clock, 9 o'clock, sticking out the top (12 o'clock) or bottom (6 o'clock) etc etc ? I've heard that anything between 9 and 3 o'clock is good (i.e. the top half of the dial) as below that moisture collects and can damage the sensor I presume by rusting. just my $0.02 worth jw
