I recently purchased a Cermark LCD Power Panel from Chief Aircraft, after falling in love with it from the catalog. When I installed it and tested the Glow Driver, when I turn it on, the lowest setting indicates .7 Amps, and the glow plug is red hot. I don't believe this is correct. Shouldn't it start at zero Amps and increase to like 5 Amps??? I am afraid to use this on my plane fearing it could do damage to the plug or Engine... Is there something wrong with my panel?
