You obviously have a few skills Tess, the electrical diagnostic manual for your bike might be worth a read, you can find pdf versions online for your year/model, I prefer the hardcopy but they can be both expensive and slow to get.
G'day g'day! Wondering if anyone has any advice - I have a 2012 XL1200N and the neutral light has not worked since purchased about six months ago. Took it into Harley recently and they said it's a very common issue and they could replace the instrument assembly, but that would be about $410 plus labour.
