spotty ignition

Keyed ignition in the cockpit to start my A4 is acting funky. She works... then she doesnt... i climb in the quarter berth and jiggle the wires (scientific, i know) and she will fire off again. anyone know a good procedure to isolate the problem? frankly all wires could probably stand to be replaced if this is the problem or not... just looking for a way to diagnose the issue.

thanks all

Sounds like a bad connection and/or corrosion. Check all the wiring and connections and maybe replace some while your at it. I had a similar problem soon after we purchased our boat, it was a corroded negative wire on the battery terminal, replaced the lugs and added heat shrink tubing and all is well.

T37 is right on the money, IMHO. In addition, from my experience years ago as an auto mechanic, you may ultimately find it easier and quicker to just replace the wiring, rather than trying to track down the one bad connection. Diagnosing intermitent electrical problems is one of the most time consuming and maddening projects I've ever encountered.

We had intermittent problems - sometimes she'd crank, sometimes she wouldn't - and solved it by running a new tinned wire (don't remember the gauge) from the starter button directly to the solenoid.
