Hi everyone,

I installed an iPod through the 6 point adapter to my 1971 mercedes 250 (blaupunkt).

Everytime I start the engine, a whining noise cuts in. I suspect it's from my distributor (whines when the car moves; doesn't make a peep when the engines off).

Someone told me that it may be a bad ground, so I replaced the negative battery cable. I also installed an noise silencer to my radio.

...still whines.

I replaced my original points in my distributor with pertronix (so I removed the condenser that suppressed this noise from the diz; but still kept it as parts).

Question: how can I make this whining noise stop (can I still connect my diz condensor to the electric pertonix upgrade; any other thoughts?)

Jub
