Electrical problem
1985 Other Suzuki Models 4 cyl Four Wheel Drive Manual 250000 miles

I've had intermittent problem starting my 1985 Suzuki Sierra.Sometimes it would crank over and other times it would not.Now the problem is permanent,it will not crank over at all.Has my ignition switch worn out and needs to be replaced or could there be another reason why this is happening.I've checked the battery,it is fully charged and when the engine was cranking over it sounded like the battery was charged.Thanks.....Mark
