Sky-tec Starter wiring

Vans recommends one way. Sky-tec another.
Which is best and did you add an indicator off the contactor "I" terminal?

I have no indicator but would put one in if building again. Mine is essentially wired like the Skytech drawing but I have a brass bar between the Master and Starter relays with a #8 wire coming off the Master, going to the ANL (if I recall), which feeds the main buss via 10 or 12g wire.

Wire it the Van's way. This option keeps the starter from being "hung" after the engine is started. Why? The current from the "I" terminal is used to energize the starter solenoid instead of the primary motor current (big fat wire.). With a PM (permanent magnet) starter motor, it will turn into a generator when turning and primary voltage is removed -- this in turn keeps the starter solenoid energized and the "Bendix" (pinion gear mech.) engaged with the starter ring gear.

...and yes, run another wire from the "I" terminal to the engine monitor (Garmin GEA 24, GAD 27) so you can see if it's energized on the EFIS CAS display

*edit* Don't forget to add protection diodes...

Thanks Brian. Exactly the explaination I wanted.
