Hi all, riding an Aprilia Mojito Custom '07, 125. So the problem:
-A bunch of electrics went out - headlight, rear light, fuel gauge etc. So I took off the apron, and eventually found there was a bad connection around one of the fuses. Cleaned that up, and now all the electrics were back on, only...
-Now it won't run! I can turn the key for 15 seconds and it might weakly kick once or twice. This was only hours after having last ridden it, and before all this it was starting straight away. I'm getting a spark, can clearly smell fuel on turn-over, spark plug comes out wet afterwards.
-I thought maybe I broke some other weak connection somewhere while unplugging stuff to diagnose the first problem - in particular I saw that one of the other fuses leads to the automatic choke. But there is current going to the choke (8-9v DC - I also checked the resistance across the terminals for good measure - 25 ohms), so that doesn't seem to be the issue.
Thanks for reading!

are you getting a check engine light immobilizer?
compression?

I have compression - did the finger-pop test.
Not sure which light you mean, I have no immobiliser - I'm getting the correct lights on the dash (red oil indicator and the green headlamp indicator).
Further development - I've found my kill switch is a bit dodgy. With multimeter probes inserted across the wires you can see that the kill switch only works properly in a certain sweet spot. But the bike still won't start even with the switch in that spot

Bypass the kill switch and try again.

Thanks to everyone who has replied so far, any more ideas?

Right, final update - it now runs! I'm not sure why, or why it wasn't before, which is slightly unsettling. Basically I tried cranking it for 10 seconds and got nothing, waited 15 seconds, did it again and got a few kicks, waited another 15, tried again and it ran (this is with the kill switch reconnected too) It doesn't usually need that sort of faffing about, and now seems to have gone back to starting straight away as before. Odd! Anyway, thanks again to everyone who chipped in!

was it one day good one day bad? or was it you didn;t start it for a week and no start?
I suspect fuel problem.
