Well I think I fixed it all I re wired the box with Blade style fuses fixed a few grounds and put the correct fuses in it and well nothing appears to be getting hot :crossesfingers: Thanks for the help guys

Well found part of my problem over half of my fuses were 30ampers. The other ones were 20's. I rewired the whole fuse block with in line fuses and it all seems tobe good now :crossfingers:

Seeing as my work didn't have the relays I did what Ddgonzal said and just put in a inline fuse using same size wire gauge and correct fuse rating and now I have MORE NEW issues!! So here goes (See pic for reference)

Ok so the yellow lined fuse gets HOTT! when I put the key in the on position and cools right back off once I turn the key off

The Purple gets hott as soon as I pull out the lights for running lights only and gets cold as soon as I turn it off. It got hott enough it actually started melting the fuse box

Light Blue well it doesn't get hot any more that I can tell I upgraded it to a Blade fuse and well it doesn't feel hott.

Red wire can't remember what it went to but well now it gets hott and cools off once I turn off what ever it went to

All I did was installed a inline fuse didn't touch any other wires and now all these others fuses seem to get hot and hot as in burned the #OOPS# out of my finger touching them. I did notice that the BIG white wire coming off the fuse block got warm now aswell Can anyone tell me why this is happening and what the big white wire is I'm thinking it's a ground from the way it connects to the negative side of the fuses. So if it is a Ground could I just hack it off and run my own to the Chassis or where ever I want? I looked over the wiring diagram Ddgonzal gave me awhile ago and it seems my wires are different or I'm dumb and cant read the diagram.

Cool thanks for all the help guys I will be tackling this tomorrow after work and I will post if I have success or failure lol

Ok I think I have it, but one last question how does the relay keep the current away if there is still power going threw the stock switch and fuse??
Is the switch more or less just now a lower circut that just provides the small amount of juice the relay needs to trip to allow the "new Full" juice from the relay to go to the lamps?

Datsun1000: Yea I saw that earlier but I am confused about the switch part. Do I use my stock light switch or do I have to wire another one inside to like a toggle switch or something? For some reason this makes no sense to me and I'm not a wiring dummy I know how to do it lol but I've no never really played with relays before

Do you mean ground them when you say earth? Also for the switch I use my current stock switch I just use the high/low beam out puts right? If so do I leave the stock fuse in the block?

EDIT:
Sorry for all the questions but I just don't wanna screw anything up the whole object is to restore the Datto not burn it to the ground lol

What do you mean by relays Earth?

Do you have a walk thru and pics so I could modify mine please

Has anyone done this to there 1200? I've tried the Tech Wiki but came up empty handed. On the other Datsun forum I look at for assistance they have done it to there trucks and 510's. They say it makes the lights brighter and draws current away from the switch and cures the over heating issue. But unfortunately none of them have done it to a 1200 so they can't tell me what wires to modify anyone have any info on doing this to a 1200?
