<VV> Cyl Head temp gauges

[Padgett]

I have the dual unit ( 
http://www.aircraftspruce.com/catalog/inpages/smicrocht6.php ) - extended 
with a two pair cable. The reference points are inside the air duct in 
front of the engine. 14 mm probes under  #2 and #5 spark plugs seems to 
work well, reading about 300F on Interstate. Doors open at 200F indicated. 
Need to order light separately.

See installed http://padgett.ws/files/dashcht.jpg - glass face needs to be 
removed to reduce glare if in dash like mine.
