My '68 280s has a recurring electrical short that I've been trying to chase down for years. On startup (seems to happen with some predictability when car has sat for awhile), car will kill when any pedal, signal or gearshift is touched. I then have to cycle the ignition many times and then car will work normally. During these cycles I turn the key halfway, generator light comes on in speedo gauge, I activate an electrical item (signal, brake pedal, wipers), generator light goes off/ gas gauge needle goes to zero, turn off key and repeat, over and over.

Battery, alternator and voltage regulator are all recent. I've cleaned the grounds under the hood. After reading up on grounding on the sl113.org page (http://www.sl113.org/wiki/Electrical/Ground) perhaps the ground on the inner dash will have to be next on the list.

Thought I'd seek the collective wisdom of the group and see if you guy had any ideas. Thanks!
