Hello guys.. FIRST.... to save any responders time please do not recommend changing the starting system to another style, I am keeping this Jeep as close to original as i can. It is a 1952 CJ3A with an AutoLite MZ-4162 starter.
While in camp last week the starter failed to engage. I have replaced the starter rod block which attaches to the firewall so the rod contacts the lever correctly.
What happens is nothing. First thought was dead battery, battery charge good. Turned on the headlights and engaged foot starter to check for a heavy discharge, lights did not even flicker. Checked push rod action, lever hits switch squarely and switch appears to depress normally. Battery cable connection is clean and tight. Removed switch to check contacts and found no issues there, contacts clean and no pitting or signs of arcing present. Using battery disconnect switch connected battery cable to starter, closed switch and motor spun, next engaged bendix and closed switch and starter spun engine. Reinstalled everything and starter worked as normal.
No other failures for rest of trip. I figure it will fail again when between a rock and a hard place. What would you experienced fellows check next? Could there be a mechanical obstruction preventing the bendix from fully engaging thus preventing the contacts from closing? Or some sort of internal electrical issues? Any thoughts appreciated. Thanks.
