I'd call back & ask for the next person up the food chain until you get to the boss, if necessary. That's nonsense, coming from a specialty vendor like B&C.

Yes, I have seen the PDF. And yes, you would think you could ohm out the terminals. And yes again, I agree, it does not look like a very complicated device. However, there is no continuity between the "I" terminal and any other terminal. Hence my inquiry to them. I am still wiring so I have not energized the contactor and checked it in real world operation yet. My questioning to them was whether the "I" terminal is suppose to go positive (+12vdc) on contact closure and have continuity with the "M" terminal or, have continuity through the mounting base and thus go negative (-12vdc) on closure. It would make a difference on the annunciator wiring. My assumption tells me it would go positive but I didn't want to assume anything. I called and talked to both of them and neither could tell me how it worked nor could they provide a schematic.

I assume you have seen the PDF that explain how to wire up the unit ? Link on the B&C web site ...
You should be able to ohm out the "I" terminal ...
Not a very complicated device ...
All the best

I purchased this starter contractor recently and I was surprised to
see that there was no identifiable manufacturer and country of origin markings on this part.
B&C declined (refused) to give me this information and suggested that if I were dissatisfied,
I should return the item..htnbsp; -Matt Dralle,tribution" target="_blank">

John,
Thank you for this. I had not seen it. I do see it is "driven" by +12 on the diagram you sent.
Thanks again.

Connect 'B' terminal to battery
Connect 'M' terminal to starter
Connect 'S' terminal to your starter button (+V)
---
'I' terminal can drive (by definition +V) a starter engaged light

I'm not sure what is being asked here (ie: subject line - 'pedigree unknown') but we are now talking about the "I" terminal, which is shown on any (eg: Z series or B&C) wiring diagram goes live (+v) when the contactor is closed, therefore can power a light which says 'starter engaged' !!!

Problem solved!
I don't recall ever flying a piston aircraft that had a "starter working" light. Perhaps it is not a bad idea!

Hi All,I have it in my RV7 , finished in 2007 and it is a great reminder that the starter has disengaged after initial start up

It would certainly alert you if the starter was "stuck" in run mode after the engine started due to the Contactor frozen in the start position.
