Ignition problem
Maax1200:
I will check again with another meter and thank you for the link.
With that said, the problems keep flooding in. I removed the assembly behind the left side cover to check faulty wires and a general cleanup. Checked for continuity and all seemed ok, no broken wires etc. Reassembled everything aaaaaaaaand.....the bike is completly dead, no lights no nothing, just utterly dead. Iv changed nothing between removing the assembly (starter selenoid etc) and reinstaling it again, very carefully i might add. Its like the fuse popped except it hasnt.
Im on the verge of giving up. I will check everything again and after, if i dont find the problem, its of to the lowest bidder im affraid (Have several other projects that need attention to and there are only so many days in a year).
I mean, everything except the coils and the sub assembly behind the left sidecover is brand new so how many culprits can there really be?
fogrider:
If you mean that little cover on the left next to the coils, that's where the main earth wire goes to the frame on mine. Is that OK ?, have you disturbed a poor earth connection ?
Worth a look maybe....
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.

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.
