When you say end to ground you mean test continuity between the end of each wire coming off the left controls and the black and white ground wire this way I know all the switches are going to ground?
Kinda
Useing the wiring diagram follow a circuit and test the continuity of the circuit.
A Powered circuit should not have a high Resistance to ground (or earth)
A Ground circuit should have low resistance to ground
A complete a circuit such as for a light you need power and ground to
A way to run the power and ground to the light a switch to turn the light on and off
power supply such as a battery with 1 poles one positive and one negative
The negative side is ground and is connected to the frame or any other metal on the vehicle and can be switched or just grounded to the frame
The power side goes to the part you want to energize , in this case a light,
The light will have 2 poles a positive (power side) and a negative (grounded or earth side)
When connected to the power supply(the battery ) this completes the circuit.
The switch allows control of the circuit turning the switch on energizes the circuit allowing current to flow.
To answer your question

You want to test the circuit the test the circuit to ground
All grounds or negative will have little to no resistance when checked with the Ohms meter to ground or the frame. if you have no resistance then you have a dead short or broken wire
Positive should have High resistance when checked with an ohms meter to ground
(if the needle or gauge dosent react then that is high resistance or no contact to ground )
If the positive shows low resistance when checked to ground then you have a positive short in the positive side of that circuit which will cause a fuse to blow
A circuit with a switch will have low or no resistance with the switch on and high resistance with the switch off
I use a bar graph meter because the bar is more sensitive to changes
I hope this helps
