2010 Murray Electrical issue

[BGS Mex]

I have a 2010 Murray MODEL: 42L18G60X8A SERIES: 080310001196 that electrically is driving me crazy.
Issue: Although the starter solenoid tests that it is operational, it does not function with the key switch (new). The white wire has voltage when the key is turned to “start”, and the black has continuity to ground. When powered directly with 12 v. at the solenoid (the terminal for the white wire), the starter operates as it should.

There are no obvious damages to the wiring harnesses and the (new) fuel solenoid operates. I have tested everything (Meter) that I can think of, however there is no change. I have been unable to locate a wiring diagram for this model.
Does anyone have one?

all your safety switches tested to show current going through them, Joe

Yes: and the 4 terminal seat switch has continuity (when connected and pressed down) has continuity between the Green and Grey conductors. All the others seem to test Ok. The thing that baffles me is that when the (new) ignition swich is turned to "Start" (white) there is 12 v yet it doesn't activate the starter. When I put 12v directly to that (white) terminal the engine turnd over as it should. I have been unable to locate a wiring schematic for this model!

May want to try a test light on that white wire to see if it will light a light. Just because a meter shows 12 volts doesn't mean it will carry enough current to engage the solenoid.

Thanx so much; I will check it again. Thinking about it; at one point I thought there might not be enough amperage there.

I think that I have watched every related video at least twice.

Trace the white back and run a separate new wire to the switch S terminal that supplies the 12v solenoid. If that works you're looking at two relays that must operate to send power on to the solenoid.

The red wire at the ign switch plug is the 12 volt feed not the white wire. Put a test light at back side of wire harness and turn key to is if switch is sending voltage out to starter solenoid. If power is coming out of switch test at starter solenoid the same way. If good there make sure ground wire to solenoid is on
