Had a couple of minutes while waiting for someone to show up here so I pulled the cover off the gen control box to back probe the LED's.
The standby LED is normally on and that read 1.94 vdc.? I pulled the connector on the low gas pressure switch to make that LED come on.
That was also 1.94 vdc.? According to the controls manual, some of these LED's besides just coming on solid can also blink one second on and one second off.? I'm curious if a versiport can handle the blinking end of it and also the optoisolators.
