R32 Headlight Wiring

[Duncan]

Can someone with a (working, or at least wired up ) R32 do a quick test for me? I'm reworking the wiring in the racecar, but funnily enough the headlights are the most complex part in the car....

Under the bonnet in the fuse/relay box is a brown relay labelled H/LAMP. Disconnect that relay (unplug it from its loom below). Then, try

1. Low beam headlights should work

2. High beam headlights on should work

3. Flick high beams should not work.

The wiring for the headlight switches is crazy complex for my little brain, so I just want to check my understanding that the relay only controls high beam flicking.

Doesn't seem to have any effect on h/lamp operation.

lol, so all 3 worked relay-less.....odd. Nissan aren't in the habit of doing stupid stuff for no reason

can I ask a small clarifying question....did you turn the low beams off before flicking the high beams?

Thanks for helping

because...I just double checked, there is a 10a feed from the tail light fuse which goes to the output of the relay, ie it may be trying to draw the whole high beam current through the tail light circuit with no relay in place. resulting in your car burning down.

Sorry Duncan. Just re-checked - flash doesn't work if relay out & lights off.

Awesome, that makes perfect sense, thanks
