TOPIC:

Each fuse is it's own circuit. I saw no realistic means of bussing (bridging) two , internally - (The 30amp MAIN and 10 amp FAN) - so I did this on the outside with a small loop of wire from MAIN 30A "IN" to FAN 10amp "IN".
DO NOT USE THE SUPPLIED FUSES - THEY ARE SHIT ! I had the MAIN 30 melt No issues after replacing it with some GOOD quality fuses from an auto-parts store.

What I’m saying is in the original fuse box there is a wire soldered to each end of each one of the 5 fuses . The fuse boxes I can buy here have only one connection for each fuse . So for example the 30a main fuse can I crimp those both together with a spade connection and put it on my new fuse box with a new 30a modern fuse ?

I guess I'm a bit confused On my '80 I also had the individual circuits soldered to the terminals on the bottom of the fuse holder, with a buss connecting the 30 amp Main to the FAN. Obviously this was so the fan can come on / continue to run, when the key is OFF.
So if I'm understand the question correctly - Yes -you can "crimp" the two together. As long as you do so on the power IN side of the fuse block you are using.

Being someone that likes to fabricate stuff from scratch, I did basically what Scotch did, but, with a twist. I use mini circuit breakers, and they are replaceable with a large sized flat blade fuse, should the breaker...break. Haven't had a problem since doing that, and, no evidence of melting the housing from high current heating issues since then, either.

That's interesting! I have a selection of "standard" size suitably rated aviation circuit breakers that I considered using. In my case I thought the O/A "stacked" size precluded their use for where I wanted to place them. Would appreciate a photo of your "Mini's" installation. Curious to see if you used a fuse-block with blade-type Mini breakers in place of standard blade-fuses. A quick search just now suggests that I "could" replace my blades with blade type "Mini's" if I chose to. There's always another way of doing some things !

I use the blade type mini's, and built my own box from a section of rectangular plastic. Lots of build/design latitude when you do it yourself.
