Hi All. Sometimes when I go over a bump, particularly at high speed, my speedometer drops to zero and I lose power.
After several seconds it returns to normal and the power comes back up.

Any ideas? 2008 xB. Thanks, Dennis

Best guess would be a loose connections at the battery or the grounds under the air box. Check them over to see if they are corroded or loose.

 

Thanks Greg! I'll take a gander and see what I find.
