john deere 757 ztrak

According to switch labeling you have the wrong switch.



Don't use the Oregon aftermarket switch as it will rust and fail. Simply poor quality.

Then whoever at JD sent you the drawing has no idea of what they are drawing. Wire positions are correct but their terminal labeling is wrong which suggest they are looking at the wrong switch.

I just verified that the Stens 430-128 ohms out correctly here. as a replacement for the TCA22740 per the make break table I posted. So ohm out the current per that table. Also note the Stens doesn't have any labeling on it. Also this switch is the Indak 4A463A switch.


Off position contact only between M and G
On position contact only between B and A
Start position there should contact between B and A and separately S1 and S2.

Here is the full wiring schematic for the 757 Ztrak.
