Re: [alfa] Bosch distributors

Don't hold me to this however according to my manual the (breakerless)
ignition system was fitted to cars built after late 1983.
There may be a few motronic equipped alfetta/guliettas around but the efi
didn't really come on until the ts was introduced.
A friend has an 84 gullietta carburetted, with electronic distributor,
revised air box and cam cover. This car also uses the g/box with the
isostatic (gtv6 type) arrangement so I assume it has a gtv6/alfa 90
transaxle. All standard. Oddly it has 13 inch wheels, also standard.
In Australia there were a series of cars which are referred to as updates.
i.e.: a gtv 2lt built to gtv6 quality sadly with plastic crap all over them.
I think they sold along side the gtv6 as did the updated guliettas.
Anyway this electronic distributor bolts straight in and simply wires into
the existing loom.
Here is the manuals definition on how it works electronically wise.
Primary voltage is applied from the batt through the ignition switch to the
module,and through a resistor to the coil. The resistor acts as a heat sink.
the negative terminal of the coil is connected to the module which itself
connects to the coil.
Forgot to mention you need the electronic distributor coil (with heat sink
and module attached). It was some time ago that I wired it in however with
the diagram in hand it wasn't hard.
I must add that I still like the old marelli single point distributor. The
advance curve is easily altered and its made in Italy.
Cheers Dean
