high pitched whine after re-wire / new alternator
Just replaced the alternator in my 1979 911SC - while I was working on the 'trecity, I decided to clean up some of the wiring mess that was left over after the PO replaced the fuel injection with webers.
Everything went smoothly - but (isn't there always a "but"?) when I put the ignition in 'run', I notice a high-pitch sound from the engine compartment that I don't think was there before. It's hard to identify where it's coming from, but I think it's from the CDI module. I'm pretty sure it's _not_ the fuel pump (I'm familiar with that noise). The car seems to be running fine - haven't taken it out on the road yet. I do notice that the CDI module seems to get warm - is this normal? The PO removed all the rear defogger relays/etc - so none of that is back there anymore. any other ideas what could be the cause of this? |

you're probably correct about the CD unit. bosch units whine. unplug it and see if it goes away.

Unplugged CDI: no whine.
Plug it back in : whine-o-matic Imminent failure, or normal operation? |
