RADIO NOISE GENERATOR/BATTERY INCORRECT WIRE ROUTING

MODELS/YEARS 1983 CUTLASS SUPREME, 88, 98 AND TORONADO

CONDITION

Some 1983 Oldsmobiles equipped with a 5.0L V-8 engine may have generator feedback noise during high charge rate periods. The condition is most noticeable on manually tuned radios and is due to the routing of the generator output to the battery.

CORRECTION

The generator noise can be eliminated by routing a generator-battery low directly to the battery, rather than going to the starter motor first. This allows the battery to filter generator output directly. To correct this condition install a new positive battery cable with a generator to battery feed wire spliced into the terminal end of the cable and connected to the "BAT" terminal of the generator. It is not necessary to remove the original wire from the generator output (BAT) terminal. However, a ring terminal will have to be installed on the generator lead of the new positive battery cable assembly (except the Toronado cable assembly which has a ring terminal). See diagram.
