No ignition lights or starter connection on Countrax C400 H key change

[cjdg]

Tried to change the key starter lock mechanism today and shorted very briefly (small spark) as I fed the new lock into its hole.  Went to start it and - nothing! dead as a Dodo. Assumed it was a fuse but on checking, it was not.  Double checked the three fuses with a mulitmeter. All sound.  Triple checked by putting in new ones. All dead. Checked the earth from the battery. OK. Checked the seat cut out switch (which should not affect the ignition lights - only the running of the engine. No ignition lights. Just to be sure put a wire across the two connectors. Still dead. Went to lunch to think. Still dead. It was working with the old switch (with a screw driver as lock was effed) and put that back in  Still dead.  Battery has 12.65 volts and is fine and fully charged.  Checked with the manual and diagram for wiring to see if there is a hidden fuse somewhere else in the system. Cannot see that.  Took the top off the fuse console to get direct access to the female fuse connectors and cleaned them up a bit and put in new fuses - still dead. 

Thoughts.... is there a hidden fuse?  Unlikely...

There must be something very simple that I am missing... 

Now pretty desperate as my tiny brain is hurting and its sunny and the lawn is telling me I want to be cut!

Are you getting a voltage reading from anywhere in the wiring loom? I would check the battery terminals and earth ( I know you have checked that one) are all clean and tight and go from there.

is there a sensor switch under the seat (driver present) and or on the brake or handbrake

Yes to the sensor seat. I tested that by shorting out the connections   See photo with blue wire

I will try the battery terminals   Never thought of that 

Its obvious but they "look" good and are a robust clip on mechanism. However I will do that right now!
