Some boards look for micro-amps, some tenths of micro-amps. Always DC.
Thanks that would explain it. Maybe my meter wasnt sensitive enough to read the Micro amps on this particular unit although i know i did read .1 uA on a unit befor i cleaned it. If it was much less than that i doubt my meter would pick it up. Giving the size of this flame rod it would make since it feeds back less uA . Thanks again good to know
