Hi all,

I recently got a new battery installed, and since then (that i have noticed) I have had a few issues with the electrics.
The exact problem is that when I am driving, or stopped at lights (wherever), The radio and gauges in the dash all turn off for half a second and then switch back on...
The battery seems to be connected fine. A few people have said it may be a grounding issue.
It doesn't seem to affect the engine, however i can feel a sort of *bump when it happens.
Anybody know what's going on?
