mark64 0 Posted October 14, 2007 My B210 recently started draining my battery when parked for a few days. I switched to a known good battery and same problem. Anyone have a idea where to start looking for the problem? Thanks Mark Share this post Link to post Share on other sites
Tom_Byrne 0 Posted October 14, 2007 MY TWO CENTS: Try cleaning and tightening all the connections(voltage regulator, starter/generator, etc;)first. If that does not work, time to get the tester out and test the regulator and S/G, but it sounds to me like the regulator. Share this post Link to post Share on other sites
Dark 0 Posted October 15, 2007 check the points in the regulator (may be burnt and or stuck) Share this post Link to post Share on other sites
