Thanks Larry,
This does not alter my opinion car manufacturers (sometimes) are violating
the basic electric engineering rule: place the fuse very near the current
source - at least as near as possible and have all current users fused
anyway.
My example shows the dashboard illumination design did not cover a fuse at
all. Rest = history.
A fuse prevents a fried loom or worst case a burnt car and perhaps someone
could be killed.
I wonder if a car manufacturer might be held liable if poor design on this
when real severe damage or actual victims are actual....
Cheers,
Hans

Subject: RE: adding an ammeter to a RBI
Hans, here is a "basic" overview of the MG wiring system. This covers the
basic 4 colors, there are
over 50 colors in an MG, but all the rest of the colors are branches of one
of the following:
1) Brown wires. These are the primary power distribution wires from the
battery/alternator. They are hot at all times, and are NOT fused.
2) Purple wires. These are hot at all times, and are fused. They are fed
from
the Brown wires. These are typically for courtesy lamps, trunck lamps, etc.
3) White wires. The are hot only when the ignition key is on, and they are
NOT
fused. These are primarily the ignition circuits, and other components
required to run the engine, such as the fuel pump.
4) Green wires. These are hot only when the ignition key is on, and they are
fused. They are fed from the White wires. These are for accessories that
only
operate when the car is running, such as WS wipers, Turn Signal, etc.
