Bosch 1873-8f Grinder Problems
I have replaced both bearing on the armature thought that was causing the bad vibrations but it didn't help.Current draw seems to be high lights dim when I turn it on.Brushes are good. Took the gear head off and ran it, same problem. Armature looks good but could it be causing the vibration and amp draw problem. Thanks for your help.Taylor email at [email protected].
