FUSEBOX 1986-1990
by Lorne Goldman
This is the first of the Morgan "modern" fuseboxes. It
is difficult to pinpoint its exact dates as Morgan went through a transition
era at both its debut and its finale where cars would be fit with what
was available that day from the local motor factor on Worcester Road. To
further complicate matters, it was fit to the EFI Plus 8s first at a time
they were still making carb Plus 8s. In any event, it is impossible
to confuse with earlier boxes (which contained only a small handful of
fuses. However, it is not a very robust affair and could have been replaced after becoming defective
over the last 25 years.
WATCHPOINT: From this fusebox on, the fuseboxes
became internally bussed. Most automobile fuse boxes since the 1980s have
internal busses. (God knows where they find these automobiles terms!) A
"bus", in auto electric lingo, is an internal conductor that make a mutual
connection between several fuse positions. For example, if you have a number
of components that should operate with the ignition key on only,
(coil, fuel pump, windscreen wipers etc) why have a separate power wire
to the fuse pox for each of them? It is a waste of wire and the more unnecessary
wires you have in a car the more mistakes that you can cause.
With a bussed fused box, you simply join the power side of similarly operating components with a internal bus. Bingo, one power feed to the power side of any of them, and they will all have a power feed. Of course, if you, by mistake, put in a feed for something else into a position attached to that bus, you now have two feeds for everything on that bus. So it is VERY important to know where these busses are
in the box. Morgan does not provide a diagram that shows this and the Factory
people do not know where they are either. The result is sad. Someone installs
a radio, they bring in power from the battery for its clock and memory
settings and they install its fuse in a fusebox position.
I do not have the diagrams of the internal busses of the three primary fuseboxes from 1986 to 2012. However, they can be ascertained with the use of a multimeter and an unwired box. Check the continutity between the power sides of the fuse positions. |
