Main beam wiring

[TorqueSpec]

Hey all - nearing the end of my 360R build and am trying to sort out an issue with the main beams (high beams). Dipped (low beams) headlights work with the switch. But when I turn on the main beams, either with the dedicated switch or the flash to pass switch, the main beams do NOT come on, though the dashboard indicator does come on. 
 

Here is what I’ve tested:

- Headlight relay works

- Main beam fuse is fine

- multi meter shows power at the fuse and at the relay as expected. 
 

Somewhere along the line, power is being interrupted to the headlights. Given neither main beam works and neither switch works, I’m guessing a connection somewhere. 
 

Thanks in advance for any thoughts. Full build can be found in the build threads…

this may give you some ideas on where to look. Although it’s likely a bit different wiring layout.  
 

maybe use a tracer to find where the cut out is happening.

Got this sorted. Ended up being the Caterham installed connectors (on both sides) that were not fully seated. Improved my multimeter skills! Wish I found it sooner…

This was the connection at issue (factory wired side)

Was it the pins that weren't fully seated in the connector body, or was it a problem with the connectors themselves?

They didn’t seem to be seated fully. I still don’t love the connection - I may change it in the future.
