The capacitors are bonded with the two tooth-
type lockwashers. There are two tinned cop-
per braided bond straps. One bonds the con-
trol panel to the load spring with six tooth-
type lockwashers. The other bond strap bonds
the engine to the skid base with four tooth-
type lockwashers. The lockwashers are placed
at each side and at each end of the bond
straps. There are several tooth-type lockwash-
ers other than the ones mentioned. Two tooth-
type lockwashers bond the magneto, two bond
ends of battery charging generator to the gen-
erator mounting' bracket, two bond the gen-
erator mounting bracket to the engine block,
two at each mounting bolt bond the regulator
to the skid, two bond the regulator to the
skid, two bond the exciter cover to the exciter
frame, two bond the welding generator to the
skid base, and two tooth-type lockwashers
bond the hood to the skid base. The charging
system armature and field leads, between the
generator and regulator are enclosed in com-
mon tinned copper braid shielding, terminated
at each end with pigtail connections and pres-
