This is the trick!
Yeah, two bulbs blown or connection a bit dodgy.
But side repeater was OK, which only showed up on the static jumped test.
We know that if one bulb blows the flasher has a fast blink rate.
Didn't know that if both main bulbs blow(F&R) indicator system still semi works, relay DOESN'T, but dash arrow still flashes at the normal rate.
And because the relay doesn't work, side repeater won't flash either .. so looks like a major fault.
Weird how they set up these modern systems.
