Hi Danno! I already did my homework! I took all the measurements you asked for. I found that the brown wire that comes from the ignition key has 12.6v and stops having them after the connector. Something made the brown wire connector hot to the point of needing to separate, we'd have to figure out what causes it. Also, the gray cable has 6.6v, which seems strange to me..

I hope we find the solution! Thanks again for the time and patience to answer me.

Here are the photos that you asked me of the connector burned with the brown wire, and the turns signals connections (It took me a while because I had the connections protected and I had to disassemble them)

Measurements:

2. KEY OFF - ignition-switch connector
BR = 0v
W = 12,6v
R/BL = 0v
W/BK = 12,6v
W/G = 0v
GY = 0v

3. KEY ON - ignition-switch connector
BR = 12,6v
W = 12,6v
R/BL = 0v
W/BK = 12,6v
W/G = 12,6v
GY = 6,66v

4. KEY ON, backprobe fuse-box
W/G = 12,6v
O/G = 12,6v
BR/W = 0v
BR/BK = 0v
R/BL = 0v
GY = 0v
BR = 0v
W/BL = 12,6v
W = 12,6v

6. KEY ON, test voltage at these points

battery +positive terminal = 12,6v
B-terminal of starter-solenoid = 12,6v
White wire leaving starter-solenoid = 12,6v (pull back rubber cover on connector and back-probe)

White wire at ignition-switch connector = 12,6v
Brown wire at ignition-switch connector (harness side) = 0v
Grey wire at ignition-switch connector (harness side) = 6,6v

Brown wire going into fuse-box = 0v
Yellow/Red wire going into start/stop/kill switch = 0v
start/stop/kill switch ON
Red wire leaving start/stop/kill switch = 0v

Red wire going into start-button = 0v
press START button and hold down
Black/Red (is Blue/Red) wire leaving start-button = 0v
both Blue wires going into starter-circuit relay = 0,58v (both)
Yellow/Red wire leaving starter-circuit relay = 0v

Yellow/Red wire going into starter-solenoid = 0v (pull rubber cover off and back-probe)
M-terminal of starter-solenoid = 0v
release START button
