1995 456 GT Six Speed. So I was driving to the inspection place this morning with the running lights on and the dash lights started flickering. I could get it to do this when I touched the brake pedal engaging the brake lights. Thoughts on where to start with this one?
It does not do this at a stop, just when moving so I'm thinking a lose + or - wire somewhere. It's also all the dash lights including main cluster and the center dash gauges. They all flicker in unison. Is there a decent wiring diagram for the GT? Anyone been under the dash. I assume there is a single power source, but is there a single ground or do the lights ground as the sockets? Maybe the switch on the column? Thanks
I had an issue with dash lights on my 550 flickering while driving every once in a while. Turned out to be a bad connection in a connector to the fuse box. Found it by wiggling wires until I hit the right one and the dash lights flickered. Fixed the connection, never happened again.
You might also check the dimmer switch married to the hood release panel - that often goes bad and can cause the dash lights to flicker (did mine). An easy replace thru Ricambi. Sent from my iPad using Tapatalk
It’s coupled with the hood release - there is a wheel switch to the right - see if when you play with it if the lights flicker. Can also remove it and check the connectors, ensure no corrosion. My switch simply went bad and ordered a new from Ricambi and fixed the issue. View attachment 2520973 Sent from my iPad using Tapatalk
