My setup in my lacrosse is the same as Gr...and my red light has never come on...even when lighting....and the manual states this light will only come on in a lockout condition...which is after the unit attempts to light 3 times...after that if it fails...the unit goes right in lock out mode and the red light comes on....
This seems to be the case with mine...as when I turn mine on I hear it trying to light...and then light...and the red light never comes on during that process.
Mine is an attwood..and this information is on page 4 of the owners manual. Just an FYI...
