Brushes & Brush Holder

Ensure brushes slide freely in brush holder. If brushes do not slide freely, check for dirt or contamination. Clean brushes and recheck operation. Replace brushes if brushes still do not slide freely.
Using DVOM, check for continuity between insulated brush holder and brush holder plate. Fig 1 or Fig 2 . Continuity should not be present between brush holder and plate. If continuity exists, replace brushes or brush holder plate as necessary.
Inspect brushes for cracks. Using caliper, measure brush length. Replace brushes if cracked or if brush length is not within specification. See STARTER SPECIFICATIONS .
