Oh I would use a test light to check the two purple wires right? And use the voltmeter to check the battery voltage...
Digital volt, ohm meter. Your Fluke is an excellent tool. Far better than generic cheap toys available everywhere. From your picture, going clockwise from the top:
I'd suggest using the dvom for the tests. The volt readings are kinda important. They tell the regulator what to do.Oh I would use a test light to check the two purple wires right? And use the voltmeter to check the battery voltage...
You don't really need to worry about polarity here - i.e. which lead, red or black from the meter goes where. It really makes no difference for what you are doing. If you put the red lead on the ground terminal (-), you will simply get a minus number on the meter, or something like -13.30. Simply disregard the minus sign. The polarity (using the red lead on what you expect to be the positive side in a circuit) can be important for trouble shooting where, if you get that - sign on the meter, it means your circuit board has reversed the polarity - good to know if you are trouble shooting. Otherwise, it is not important.Which setting will I need to use? It's kind of a different language to me..also do I use this same setting to test all the things I need to test..and should the voltage remain the same at wide open throttle and other throttle settings..and will it remain the same with pto and lights on
What should the meter read when checking the purple wires?It looks to be wired correctly.
The green wire from harness needs batt voltage when key is on. Remove relay and turn key on, using dvom, check for power at relay terminal for purple wire.
If that's good, then plug relay in, you should hear and feel it click.
Check other purple wire going to regulator. This is your clean voltage from red wire.
This is voltage regulator uses to determine charge rate.
Charge the battery up. Get the tractor running and check the charging voltage. It should be 13.5 to 14.7 volts.
