HI Guys,
When i start my 8v mk3 it sometimes for a split second acts like the battery is flat and a micro chirp from the alarm and my clock milage and everything blank and reset? but car then starts fine! but i dont want to wait till it wont start.
I fitted a new starter motor about 5-6 months ago when the old one just completely died

Im guessing this is a bad earth? is there a favourable place to start? bit of a novice
Thanks in advance for any help!
