I have seen a lot of these modules. They are the green ones that Heat n Glow and Hetilator use on there electronic ignition units.

How many mico amps do they need?
Oh and one more thing. I have seen them send power back to the battery pack. This caused the new Batteries to split open. This can't be normal. Is the module bad?
They back feed voltage to the battery pack all the time. Batteries should only be installed when the power is out and removed once it is restored. Unless you have an upgraded wall control that auto switches to battery backup (WSK200 or WSK300).
I have never found the need to test the micro amps for the rectification system.
This IPI system is not very discriminatory. It can usually run with microamps anywhere from 0.5 to7.0 .
Keep the fire inside the fireplace.
The Pilot was cycling several times before the main gas would remain on. I found about 1 micro amp before I cleaned the sensors at the pilot. It then went up to about 4-7 and did not fail again.
