Strange shut down

[crimpdoc]

every now and then when driving along I can here a faint click noise (almost like a relay operating) then everything must shut down for like a millisecond , I noticed it more just recently when driving back from spa in the dark same click then headlights dim momentarily as fast as you can blink dash off then on !!

Any body have same issue or know of a common fault before I start checking things out ?

I've tried a search but it's diffuclt to find anything these days

Same here, never worried about it because everything is working fine.

I have the same and I think it's happening when the radiator fans are kicking in. After all, it's a TVR!

Same here. Not a shut down though, just the lights dimming. I'm pretty sure it is when the fans kick in.

It will be the fans as they draw more current from the battery.
