The 4D batteries in my Catalina 320 don't have built-in threaded terminals but rather simple lead posts. So they use "military style" top post clamps (pic).
Now I need to install battery terminal fuses, the cubes that sit on a rectangular saddle, whose lug is tightened against the horizontal screw of the top-post clamp (far right in the first pic). To get a neat installation, I've got to position the fuse saddle to sit astride the battery post. And to do that, I've got to put flat washers underneath the fuse lug. Otherwise, the clamping nut prevents the fuse assembly from sitting flat on the clamp.
Now, I know that it's a no-no to put stainless washers under a battery lug. (I assume that's because stainless is a poor conductor.) (Ref: Compoass Marine How-To's; 'Battery Meltdown Averted' section)
I found a bronze bearing that looks like that thick flat washer and can sit between the top-post clamp and the fuse holder. So my question is, will the bronze provide enough conductivity to keep the installation safe?
