If the OD solenoid does show any problems, possibly take a look at your voltage regulator. It may be, that upon acceleration, the voltage from the generator is going up, and the voltage regulator is trying to compensate. If it is defective or mal-adjusted it may not be reacting properly (constant on-off).
Longbox55, thanks for the OD parts link, good resource.
