I could use some help from Ed and any of you who know more electrical than I do. From my best reading of the 79 FJ40 electrical wiring diagram, the starter is triggered by the ignition switch turned to the Start position, which is fed by the 15amp Engine fuse to the Black with white stripe wire. It appears to be 14awg to me, to match the 15amp fuse. So I want to use this switch for my engine test stand, to trigger the starter, but can't make out if it is up to the task alone, or if I need to put a relay on it. I see what I think is a 10 AMP rating on the #3 feed connection on the left, but am confused by the Ui:600V, and output "AC15 and 240V-3A" on the right. This switch is part of switch panel I got off Amazon. With those high voltages it seems like it was made for AC use perhaps? Is there some conversion formula from AC to DC to determine the switch capacity? BTW, the switch circuit is activated by pressing the green arrow looking thing on top. This is pressed by a different LED lighted "Engine Start" button switch thing. Any insight is appreciated.
