Did some "wire fixing" and now im having prob.

ok I was messing around and fixing/upgrading some 1974 premo wiring. I put new battery cable on the ground and put a new cable end/ battery term. on the +. I also replaced the + wire running from the battery into the cab to the "main fuse" on the pass. side behind the seat on the cab wall. I ran some nice & pretty, Nasty guage amp wiring that I bought to do multi stereo upgrades and some wiring upgrades also. Any who, All was well & good for about 3 days... 200-240 miles then on day 4 she fired up and i went to get gas and after filling i hit the key and it was dead. nothing jack and sh!t. I checked the batt cables all were good and tight.... ok next stop is the main fuse block deal behind the seat... they were all still inplace and felt tight... so i jiggle all the wires... when i jiggled the 1 from the battery the guages came to life so i jumped in and goto work. At work I tightened the conectors thinking this would fix the prob.
NOPE, almost every time i get in to start it i have to jiggle the main in wire.
What im thinking about doing is replacing the old stock main fuse block with a new unit... prob something like a car stereo sys. might get. so i can keep the 3 main power fuses fused... i think its a 50amp and a 20 and 30. ill have to hit the wiring diagram book to check.
Has anyone else changed out the fuse blocks and if so what did you use/do? Im also planing to(later date) replace the stock glass fuse block under the hood with a newer style blade type or maybe do the fc style underhood block type fuses. this will also give me some aux. fused ports for things like headlight wiring upgrades, air horns(a must, all my rotors are invisable to other drivers), elec. fan... Flex o lite Black Magic:) , fog lights ect.

Please keep us informed on this project. This friday I've got to replace the + cable on my 74 because it sometimes shorts out.

If you suspect the fuse block...:

...have you ever removed it, and not only cleaned it scrupulously, but also cleaned/redone each and every cab/chassis ground...? A wire brush and a few droplets of a 'De-OxIt' type electronics contact cleaner *may* work wonders.

That is, if it's not something else...

ok i did alittle work on the 74 this morning. i did the mod to install a internal volt reg. alt. other than the exh overheat light its working GREAT. I also replaced the large wire on the alt. i just replaced it from the alt to the drivers fender connection. I also did a little on the rear fuse block. i replaced the female tabs with small ringlug ends and removed all the fuses and screws cleaned them up with 3m buffin pads and then installed the ringlug on the screw that holds the fuses. so far its working GREAT.
I also installed 3 8 guage grounds. from the body to the intake, body to tranny/motor bolt, and body to the alt. housing. all got soldered on ringlugs and heat shrink.. and the mounting area got a good cleaning with 3m pads and brake cleaner.
I do still want to replace the old stock fuse blocks as they are near there end.
