What are the readings on stator for a 82 honda 750 nighthawk

First, test for voltage at the plug that attaches to the headlight, if you have voltage at each terminal when set to it's respective hi or low position it could only be your headlight. If you don't have voltage then you need to work back from the wire to the switch and etc etc

the screws should be the same take out the loose one and try some loctite 505 easy way to check is to take the one that works and try it on the other one

The battery is good? have you tried a new one?

No alarm on the bike is there?

Mezo.

i have found in the past its the cable not the tacho

Hi and welcome to FixYa,

Check / replace the diode that connects the clutch switch and neutral switch. The diode normally would have green/red and light green/red wires.

Good luck and thank you for asking FixYa.

Replace the neutral switch, it's worn out...

Hi and welcome to FixYa,

Stator tests:

• each yellow wire must have continuity to the other yellow wires;
  
• the 3 readings must be close or identical to each other;
  
• none of the yellow wires should have continuty to ground;
  
• there should be continuity on the black & white wires;
• all of the above readings should never be a 0 ohms as this would indicate a short.

Good luck and thank you for asking FixYa.

Possibilities are>

• Wires not hooked up properly or a wire is disconnected
• Bad rectifier or bad voltage regulator
• Dirty or loose wire connections
• Bad stator

Can I get a “very helpful” rating on this answer?
