 |
|
Other builders tell me they wired in a light to indicate that the starter motor is 'doin its thang'. They value this because you can't hear a Lycoming starter working and if it continues running, due to welded contacts or some other problem in the circuit, something needs to be done about it.
What I would really like is a light to indicate A) that the starter is available to be engaged OR B) is actually energized and working. It would switch off when the engine was running and the starter was no longer working. Such a light would come back on when the engine was cut off as long as the master is still on. This is pretty much how my car status lights work.
I am still learning about electrics but would somebody more knowledgeable know; can a starter light be wired to this effect and how would it be done?
I will be using the z13/8 architecture for my RV-9.

A simple "starter energized" light is powered from
the downstream side of the starter contactor. It's
illuminated all times the contactor is closed either
because your finger is on the button . . . or because
it's stuck. See:

Do an archives search on "starter engaged" for a constellation
of the problem and variables associated with the various
starter technologies.
