This is kinda related to contactors...
On the BD4 that I am rebuilding, the battery is behind the baggage compartment, with a really fat wire running up to the firewall. 
IO 470 engine so lots of amps required for start.
Is there a recommended contactor placement/battery disconnect protocol out there?
I'm thinking safety in the event of an incident which might short out the fat wire to the fuselage.
My setup is very rudimentary (steam 8 pack), conventional engine gauges, perhaps a mini EFIS. 
 
I did try the Forum search but struggled a little....
Best Regards,Bob Verwey

Thanks to you both for the quick feedback. I'll include the jumper from the contactor "I" terminal to the starter with the extra diode.

You are correct that B&C no longer sells the crowbar module so I was going to build my own from your crowbar schematics.

Thanks again, I'm sure I'll have lots more questions...
