I'm adding auxillary fuse and relay blocks for extra lights and equipment like CB/HAM radio and anything else later. I'm thinking of powering this aux fuse block with a short length of #8 wire from the primary fuse block screw that secures the red (#2?) wire from the battery. There is a second #2(?)red wire on the fuse block terminal that goes to the alternator with an empty screw terminal on the same side.
For my aux fuse block which side is best to tap in to? The battery side or the alternator side? Is one side "switched" on with the key and the other always hot?
I'll probably mount these new blocks to the firewall with one of the sheet metal bolts already in place - anyone have a better suggestion? |

I am using a Painless Wiring Harness (7 circuit water-resist) www.painlesswiring.com I think.
It completely isolates accessories from the vehicle electrical system and provides protected switching. |

right - have seen their stuff before - my question was concerning the terminals in the Disco fuse box next to the battery. I was interested in knowing if either of these hot termnals was switched hot. I checked with my multimeter and they are both hot. I was curious why htere was a split inthe bolck for the alternator wire? |

.....uh, of course, logic tells me now that the alternator is fused. So if the alternator fuse gets overloaded with extra stuff and blows I've got a bigger problem than no rear work light - right? This is a pic of the points I'm talking about:
this still doesn't tell me why there is an extra hot tap on that side of the fuse block? |

I have added both positive and negative terminal blocks on my 95 disco.. both are mounted just below the fuse panel on the passenger side wheel well. I went to a boating supply place and purchased 2 stainless steel blocks with plastic covers. Using water tight solderless terminals this is a bullet proof install. I have 4 extra lights and some other acc. stuff so it was getting very crowded on the battery terminal and main engine ground terminal... stainless or brass is the way to go.. |

great idea (Boat yard) I knew that - I just never think of "new" stuff when I do this. I always first think of "how can I rehab some piece off of a wreck I can get for free or little and convert it to my use?"
I have time this AM and I'll root around the junk yard for a while and then drive over to the coast and see what the boat yard has to offer. |

Jerry,
The terminal blocks in my diagram are straight from West Marine. Same stuff, just ordered online.

Just came back from West. They didn't have any relay blocks on hand but I did get a fuse block to use. I'm going to try Painless and see what they have in the way of relay blocks. I dislike the idea of a half dozen separate relays screwed to the wall. |

I ordered the relay blocks from www.ralleylights.com. It's a place here in PA called susquehanna. They sell hella lights, and accessories. Good stuff.
The terminal blocks came from west marine online. They are just a block like a bus bar. Plug in a single 4 guage wire, and then tap into it with your 12 guage power needs. |

here is a pic of my fuse box next to the battery, If I power my aux relay's and commo though this side will I pick up engine noise and static like you do when you plug into your cigar lighter? Also, does this terminal operate through the 100 amp fuse that the alternator uses and will any extra power drain over tax that fuse? |
