CSI P1800 continued...
Al;
...no surprise there...the entire length of the Blue wire was carrying the overload current so the entire length got toasty and can be expected to have (luckily only partially!) have melted its insulation...this is obviously a confirmed fact from the remaining evidence...the Blue wire is the incoming power to the footswitch...
...so the next thing to check is which OUTGOING wire carried the overcurrent...referring back to the wiring diagram (fotomkoplare) we can see that the Lobeam outgoing wire is the Blue/Red, and the Hibeam outgoing wires are the two Blue/White (one powers the indicator on dashboard)...from the footswitch...from the picture, I cannot make out heat-damage to any of the outgoing wires, so unless you can ( by closer inspection of those three wires) tell which is also heat-damaged, (which will send us to the next location), the switch itself may have internally developed a short to chassis.
Next Step: Very Carefully Inspect Blue/Red and Blue/White wires at footswitch for heat damage...if you find it, then go to other end of that damaged wire and continue following path of overcurrent to short...if none is apparent, internal short at switch is likely and needs to be confirmed...by disconnecting all wires from footswitch and checking for a short (single Ohms) to chassis from three terminals (especially the terminal Blue wire was on)...
...please report back...can you believe this remote troubleshooting???...it's actually working quite well...at this rate we may be at the root cause by tomorrow...and you'll owe me a pint o' Guiness!
Good Hunting!
