Hello everyone, it's seems that I'm here yet again for my yearly forum ask for something I can't troubleshoot on my 2013 Stelvio NTX.
The problem I'm having this time is that whenever I turn on the ignition, the 10A fuse in the block near the steering head pops.
I first noticed the issue several weeks ago when I started the bike and realized the headlights (and Aux lights) weren't working anymore. I replaced the fuse and it worked for about 2 min before popping again. Since then I've been down the rabbit hole.
1. I thought it might be 'startus interuptus' coming to finally get me even though I had fused the Aux lights some time ago. But checking the main (30A?) fuses on the right side panel showed them to be good.
2. I disconnected the headlights and Aux lights and it still pops the fuses every time I turn on the ignition.
3. Got new relays and replaced the ones for starting and lights logic (2x of the special 4 pin)
4. I got the guzzidiag on it, read the error codes and found a P0170 error (no electrical signal). I traced the wires from the ignition to a connector on forward, right side of the bike near the ABS control unit. I cleaned it with some contact cleaner, put some di-electric grease on it (and the other connects in that area) and fitted the tank on just enough to get the engine running. That seemed to have done the trick with the headlights and Aux lights working and the battery charging. But as soon as I properly remounted the gas tank (tightened it down) it continues to pop fuses again every time I turn on the ignition.
5. Took off and on the starter motor, checking the grounds underneath it. No change.
At this point I'm out of ideas. My instinct tells me that there's likely some ground connection with the ignition that isn't working properly, whether that's with the connector underneath the tank or some other ground wire I haven't identified. If you have some ideas or advice, I'd greatly appreciate it.
Thanks in advance
