Just this Saturday, I tried turning on my 1987 Toyota 2wd CARB'ED truck. when I turned the key and depressed the clutch pedal, I heard just a click near the starter. I thought that maybe the battery was dead, so I jumped it with another car. Nothing, same click. I then hooked up my battery charger and set it to the 40 amp start. Tried it again, nothing. I ended up taking the starter off and having my step dad test it. (35+years doing starters and alternators) . He changed out contacts and brushes. Installed it, nothing. what else can I check? If I crank it without depressing the pedal, nothing happens, as it shouldn't. What else can it be?
