The 1000 S came equipped with variations in the charging system:
Saprisa charging system. Voltage regulator was mounted behind the right side cover.
Ducati charging system. Voltage regulator was mounted in front of the engine, above the alternator.
The 1000 S came equipped with variations in the ignition system:
Standard distributor with coils located behind the left side cover.
Digiplex electronic ignition with coils under the fuel tank.
Please let me know which variation you may have.
I duplicated an original main harness. In construction, I use the same gauge of wire, the same colors and tracers (stripes), the same length and sheathing, the same terminals, etc. All terminals are of the double crimp, strain relief variety.
Note: Main harnesses comprise the main - or primary - wiring harness. Each motorcycle also uses ancillary sub-harnesses. The individual sub-harnesses are sold separately.
