Warning Light after battery disconnect

Background:
Disconnected battery to clean terminals while doing maintenance on new arrival...
Also replaced air filter without disconnecting AIR TEMP Sensor....
Also Disconnected rear turn signals and plate light....
Warning light was not on prior to starting work

Reconnected battery and started her up....a little sluggish at first but fell into idle just fine, but....
Warning light is on and stays on.
Questions:
Will warning light go off after a period of time or is it related to the (a) battery disconnect (b) disconnected lights (c) unknown?
Also.....replacing all turn signals and plate lamp with LEDs.....can I just replace the signal/flasher relay with a LED relay (and if so, where is the signal/flasher relay located so I don't have to pull the all the plastic?) or do I have to install the 10 watt resistors for each.

Thanks for any and all assistance. GRiSO looks great next to the CX, and the ST1300 is already jelous.

I've changed the number plate and the small position lamp in the headlight (both T10 fitting), those that stays on when the key is at "parking" possition, with LEDs with no problem - other than finding a LED that illuninates good enough through the mirrored surfaces. Most LEDs are focused, not illuminating the headlight / number plate enough, i think its illegal in some countries. Anyway, no fault from the ECU...

Turn signals will either need CAN-Bus LEds, or the resistors, there is no relay, they are fed directly from the ECU.

Thank you Petros.....Now I know why I couldn't find a relay listed (I'm no mechanic, so reading the wiring diagram was an exercise in futility). I suspected that the resistors were going to be needed.
Still looking for answer on the Warning light.....my CX100 is so simple......
Thank you again.

When the ignition is on do you get an icon of a globe/bulb at the bottom of the LCD screen on the dash as well as the red triangle in the upper RH corner of the display? My guess is you do and it's because the system thinks the bulbs are blown due to the lack of resistance offered by the LED's. Yes you'll need in line resistors for the system to work correctly. The lack of a number plate light triggers no warnings.

make sure the load is the same as original globe 10w here in oz otherwise ecu will not be happy

Thanks Pete.....yes, globe at bottom and triangle in TRH...rear signals worked but both arms broken in transport, reason for replacing......will have to wait for replacements to show up from Amazon. I hope I ordered correct Resistors......will get out meter to check OHMs. Now to tackle the oil filter issue....have new HIFLO with 14 flute and wrench, but bike arrived with UFI 8 sider....like I need another oil filter wrench~
Thanks again

hi Ian
You do not need to buy another just bash a couple of screw drivers up thru the arse of the old filter and unscrew with a bar between then use your new filter and socket.
cheers

As a temporary fix you can solder the old bulbs parallel with the led's and tape them off with black tape.

When ever I bash anything, it never ends up well.......Walmart (home of all things poorly made) had a universal remover for $5US that did the job. I can used it to extract other things like teeth, kittens stuck in drain pipes, and the like.....
Oil Job done....3.2 liters, and will take a quick run, top off, tighten up and move to the next project......replacement LEDS due in today or tomorrow, so will just tape off until I can install. thanks for the advice.....Will post pics when installed and running.....Wanted to buy fender tidy kit, but have already spent all my "good husband points"....don't want to loose my riding privileges.
