Hello Folks! I am trying to locate a 240Z Radio Condenser, Part Number 27984-89910 (supercedes to 27984-N3500) which is also now NLA. Can anyone suggest another Nissan number which will work for this application. Will part number 27984-N4400 or 27984-B0700 work? Any input on this part would be greatly appreciated. Regards, Rob

Is your goal to do a cosmetic restoration or to get rid of radio noise from the coil & alternator?

a 10pF tantalum capacitor, (anywhere from .1 - 100pf) from Radio Shack, mounted directly on the alternator will get rid of 95% of alternator whine. It goes between the output lug ( and ground.

Just be sure you install it correctly, they're polarized. They go off like little blasting caps if you wire 'em backwards. Want to guess how I know???

"Condensor" is just another name for "capacitor".

On the 280ZX coil, my Factory Service Manual spec's a .5uF capacitor. (In the radio section) Be sure you hook it to the + terminal, not the -. I wouldn't be afraid to try the alternates you've found.

This capacitor isn't JUST for radio noise. The coil presents a big inductive load to the charging system. A capacitor in parallel with it neutralizes a bit of that load --- when the coil is discharging, the capacitor is charging, and vice versa, so overall it uses less power, makes less RF noise, etc. Might make the coil last a bit longer too.

HTH.
