Ignition problem
Maax1200:
I mixed it up before, its secondary surcit om the coils that are faulty. Managed to get hold of 2 secondhand ones and they confirm its not my multimeter thats showing wrong. So i now, at least, i have 2 working coils (for now) but im starting to wonder if there is a problem with the voltage regulator maby, giving to mutch voltage burning stuff?
I will keep digging and rechecking earth wires etc but the whole system going dark makes me think something happend to the egnition switch, maby due to mutch voltage?
Only times i ever seen system going dark before is because of main fuse blowing (not the case here). The next thing i can think of is the egnition switch.
P.S. Thank you all for your input and hoppfully i will solve it in the end.

Worth a look maybe....

Sry, i meant the subassembly behind the sidecover below the seat.

It's clear you've just disturbed a connection that is vital, in particular check the connector to the fuse.

Will check again. I made fresh new connections to the fuse but will try again. It just has to be that or the egnition switch.

I think i have solved the problem (i think).
The original issue was that the turn signals and oil lamp didnt work. Turns out those two cables was switched on the new main harness, grey to blue/red. So now that issue is solved. So thats a tip for those who buy new "quallity" replacement parts. Allways check so that wires isnt in the wrong place.
My second issue ended in the bike going dark. After checking all the connections and confirming that everything was fine i finally came up with the idea to bypass the starter relay and viola, it all works. Now i need to order a second hand starter relay and everything should be ok. The relay turns the starter motor if i bridge the two terminals but it doesnt seem to let through any power from the battery to the main harness.
I need to check the voltage regulator so that isnt the cause giving to mutch voltage. Maby that killed the switch and even the coils (should have blown a few bulbs first i would think)?

Good work Sherlock, keep us updated. ;D
