Do you ever feel overworked? • Your vehicles electrical system can feel the same way. CBC
The three types of circuit defects are: • Shorts • Grounds • Opens • poor connections C75-78 L64-71
Fuses (Page C52 ) • Glass Cartridge How to pull them
Two reasons for blowing Where do they blow? Why?
Fuses (Page C52) • Ceramic • Used by. . . • Metal/glass replacement • Caution in pulling
Fuses (Page C52) • Auto-fuse (blade type) • Mini-fuse • Maxi-fuse • Test holes • Pulling
New Circuits ? • What size of fuse should I install? Page L53
Fusible Links • Location • Circuits protected • Insulation • Visual checks don’t work • Installing a new link • Size • Soldering C54-55 L53-54
Maxi-fuses • Combination blade / cartridge • Safer • Cover fewer circuits than a fusible link C52
Circuit Breaker • Why circuit breakers • Styles • Deterioration C56 & L55
