Diving into new project, '53 1-ton. Found answers to some questions - here's another question: I installed a 12-volt foot activated starter from a salvage yard that is compatible (gear wise) - I just don't know what the little switch gizmo is on the top (not the main foot pedal switch). This is a little cylinder-shaped thing (a little smaller than a tobacco chaw can) with three electrical posts on it - it seems to be a switch that gets activated when the starter is activated. I can supply pic if this is too vague. I'm having some trouble with the starter engaging the flywheel gear - this isn't some kind of switch to engage the flywheel gear is it?
