One coil or two?

Post by pequeajim »

I am going to use a Compoiste Design power panel in the Lightning that I am building. This has a split power toggle switch on it (master/alternator). The panel wants to see power from a battery solonoid (like a Cessna), and not wired direct.

My engine is a Jabiru 3300 and most of the aircraft built by the Jabiru USA guys just takes power directly off the battery to a 25-35 amp master breaker switch. Based on this, I have a couple of questions:

Why does Cessna use the extra solonoid?

Why dothe Jabiru guys use a breaker switch and not the extra coil like the Cessna guys? Is there an advantage of one over the other?

Thanks ahead of time for the help...
