2006 rubicon no spark no neutral light

Is the angle sensor that you put on it an OEM Honda sensor, or an amazon/ebay china knockoff? Are there any china parts on this bike? We need to know about them if there are any.

Unplug the angle sensor from the harness. Then, using your multimeter, check for continuity between each of the three terminals inside the sensor, to motor ground. There should be no continuity between any of those three terminals and ground. Stop right there if one of them is grounded and replace the angle sensor.

Resistance measurements between each of those three sensor terminals should be within the 1.6k-2.4k ohms spec as shown in the manual. See the attached image.

Now turn the key on and check for positive (+) voltage between the Black/Red wire in the angle sensor harness plug and motor ground. Put your red multimeter lead on the Black/Red wire terminal inside the harness connector and your black multimeter lead on motor ground. What is that voltage? Is it 5 volts positive?

Then remove your black multimeter lead from motor ground and place it on the Green/Yellow terminal inside the connector. What is that voltage? Is it less than 5 volts... how much less (or more) than was read in the previous test?

Now lets review your gear position switch tests... verify that it was installed right and that continuity is shown between each wire color pair, as the manual shows. Report those test results.

We'll need to add a couple more tests right here before moving on to the ECM test... so lets 1st check the ESP shift switches after unplugging them from the main harness. Using your multimeter check for continuity between wire color pairs inside the switches connector. There should only be continuity between wire pairs that are shown in the table relative to a shift switch position. Check all possible combinations to insure that there are no internal shorts in that switch assembly. Then check for continuity between each individual wire and frame ground. There must be none. If any of them show continuity to ground replace the switches assembly. Report back with those results.

Finally, perform the continuity tests as shown in the attachment for the mode switch.

I'll be back tomorrow night.

Angle sensor is OEM and all tests are good with 5 volts position from B/R to motor ground and 4.99 from B/R to Y/G. Resistance test good and motor gear turns freely.

Gear position is installed correctly and all wires test fine.

All gear switches test good.
I did some more testing tonight and found that if I removed the 10 amp ignition fues the 30 amp es fuse was fine.
I used a test light in place of the fuse and it goes to ground for about 3 seconds after turning the key on. Same happened when I installed the 10 amp fuse. After I tried this a few times the 30 fuse didn’t blow anymore. I have no idea why.
Now I have a new problem. I am now getting code 4. I have done all the tests on the TP sensor and no problem found.

Tried to do the initial set up again and can get all the way to step 8 but motor does not turn. No voltage getting to the motor. Tested all wiring for the motor and all ok. Removed motor and took it apart all tested good. Connected motor to 12 volts. It turned but wires got hot after a few seconds of turning. Maybe it the motor that is causing the codes.
