Anyway, I snipped the black wire stereo side and the test light went out. The trouble is, with the new box in, the right side tail-lamps don't work. It looks like it was a combination of the radio and the flasher. The fuel pump is powered by the white wire circuit. That's where original thought comes from. The terminals on the left side of the fuse where the white wires connect is a three-way splice, 1 one wire coming in from the ignition switch, 2 the left side of the fuse, and 3 a white wire going to the coil. I always try to use the factory wiring diagram when possible.

Do you have any more questions? Some of these items only have 1 wire attached to them. Good luck and happy 'sorting'. Are you having a particular problem with your car? The breakers or fuses are used to divide your home's wiring into various circuits. To the intelligent person, life appears infinitely mysterious, but the stupid have an answer for everything. I can't find the cover for the fuse box, and I'm not sure that it would have this information on it, so what does that particular fuse control? You can also try your local public library for books about automotive electrical systems. After snipping the wire, I plugged the flasher back in and the light came on. These should be split righthand side top and second fuse down.

There are a lot of loose wires in that area. The ignition is not fused. To answer your question there is no problem.

So, question is: are there any internal cross-overs imbedded in the plastic block, or do all 4 fuses simply pass power from the spade connectors on one side, through the fuse, to the spade connectors on the opposite side of that fuse. Here it's really just a stack of inline fuses. Now, if I plug both sets of red wires to the top terminals, all the lights work. It is a common problem.

I got the gas gauge to work as well as the wipers by reconnecting one of the wires to the fuse box. Probably the same thing you've got - Triple C was having a sale on new Lucas fuseboxes at Carlisle and it was too good to pass up. Bottom fuse purple circuit is hot all the time as it is fed from a brown wire directly from the battery powers courtesy lights and horns. Those items will make it difficult to diagnose and fix, but not impossible. In practical terms this makes no difference as it feeds both fuses.
