HELP: electric/fuse - for V8 radiators Options

[jimkelly]

I test ran my engine after running a bunch of wiring and fuse blocks for my horn, wipers, and radiators.

the blocks are rated for 6 fuses, all can be 20 amp circuits.

I had one 20 amp fuse (in my dash fuse block) feeding my front trunk fuse block, which had two 15 amp fuse for each radiator, and a 10 amp fuse for my horn.

when the engine got to temp, the 20 amp fuse in my cabin blew.

I can only keep it from blowing if I run only one radiator by leaving one 15 amp fuse out of my front trunk fuse block.

looks like I have no choice but to run another (10 guage 12v) hot from battery to radiator area, to a fuse block that can handle at least two 30 amp fuses, one for each fan.

thanks guys!

new wiring - will put a 50 (or 100) amp inline fuse near battery today.

I currently have..
a 10 amp fuse to horn switch - will put a 5 amp fuse
a 10 amp fuse to wiper switch - will put a 5 amp fuse
a 10 amp fuse to horn relay
a 10 amp fuse to horn relay
a 20 amp fuse to radiator relay pass side
a 20 amp fuse to radiator relay drivers side

it seems 10 guage wire can handle up to 100 amps in a 10' run, which is about what I have. (a 10' run, not 100 amps of auxillary stuff)

for the moment, I installed a 100 amp circuit breaker between battery and circuit. I also put switches on a panel for easier access to them.

just ran it, got to 190 degrees, fans (2) came on and brought temp back down to about 165 or so. tested wipers while fans ran, all good, so far.

time to hit the road. need to get registered and inspection, though I still think I have crap in my gas tank, after numerous replaced filters and partial gas drains, and fuel pump flushes. current fuel tank far better than removed tank BUT not perfect.
