I have been installing a Skyview system in my RV6 and came across the need for a diode to protect the Skyview from ?flashback? from the Master solenoid (did not use one 22 years ago when I wired the RV6).
That got me to thinking about why I even have a Master solenoid in the RV6, and more to the point here, whether one is really needed in the RV12. With the higher loads on the main buss (pitot heat, high amp landing lights, etc.) I sort of see the reason on the RV6.
So I thought I would ask the question here. On the RV12 weight and electric load of the solenoid are more of an issue. I expect there are simple switches rated to handle the normal (non-starter) electrical loads of the RV12 (especially mine which has no lights). If that is the case, why is the Master solenoid needed?
The only reason I can think of is to provide the ability to shut off the starter if it were stuck ?on?. That leads to questions about starters. Do they get stuck ?on? on RV12s? If that happens how do you know, and what is the result?
