I got an engine buss connectect direct to battery, power goes through fuses to toggle switches to each component. Pretty straight forward & simple. Having another way of power to the engine buss would not have helped as power would still not have got past the corroded fuse. Redundant system would entail complete duplicate system right to the connector on each component with diodes where they join, this at the moment is just too much for me to contemplate.
Will look at better circuit breakers though.

Does your wiring include an essential buss for all devices needed to keep the engine running?

Using the AeroElectric scheme you have two independent ways to get power to the essential buss.

If your dual fuel pumps,, leading / trailing ignition and primary/secondary fuel injectors are on the essential buss it takes at least two major power supply failures to stop the engine.

 

I agree with Bobby – circuit breakers are more reliable than fuses for essential items.  Also – I had a rocker switch fail to make good contact – changed all out to hard snapping toggle switches..

Andrew,   Electrics -- I hate them as all looks the same if it works or not.  At least with mechanics you get a half gear missing which is obvious, not so with electrics.  I wired my fuses with a 30 amp fuse so that without a solid short it should never trip.  Redundancy is the never ending discussion --- just where do you stop?  LIke Dick Smith said, we need "affordable" safety, not a full second plane towed behind.  Only time I have trouble starting is if batteries get below 11 volts, otherwise second turn every time -- noise.

Question to all, just what sort of connection can I put in my electrical circuit to take jumper leads??  My baron had a female plug on the outside for those occasions.  I want something similar on the inside that I can plug into without having to dismantle the seats to get to the batteries.  Bad enough having to find another battery let alone a full tool kit as well.  Suggestions??

Neil Unger.
