544C Loader Will Not Run

[garebear]

I have 544C loafer that will not run without ignition in on position & using my remote button at starter selinoid.
When running the panel shows stop, park lights flashing & it will not go into any gears or shut off the park brakes.
I check fuse, relays, main shutoff switch, selinoid & its getting power to everything it should but it stoll won't start at key switch, shut off parking or go in drive & reverse. Im getting at my grey hairs ends. Any tips or idea's would be greatly appreciated.

Welcome to HEF garebear .
From your instrument panel description doesn’t sound like you are working on a Deere 544C.
You have the serial number ?

Thanks for welcome & replying. Ya it might be a 544G. I've looked every where on the unit & cant find a plate with a date mfg. or any other monoclasure. I'm assuming it's a 96'. The plate in upper right corner shows,
Model # 924399
Serial # 549841

The plate should be under the cab behind the steps to get in.

I'll take a look again & get back with u.
Thanks

@garebear , Does the monitor panel look exactly like the screenshot below?
If yes, it’s a Deere “G” series loader.

Yes it look like your pic. So I'm dealing with the 544G Model. Tht may explain not finding a tag under or next to the steps. The tag I located was in the upper right side of cab:
Model # 924399
Serial # 549841
I'm back working on this loader & still have not found a solution. Been checking all the switches to the brakes, transmission & haven't found a problem. Has anyone run across this problem. Thanks in advance

Thanks Dave for the schematics. Do u have any advice which controls or system I should test. Qht might be the most probable causes? Thanks

I would begin with the start circuit.
Find the fuse and relay panel layout below, in case yours is not readable.
