G'day all, first post. Just started my HD journey at 62 and took a chance on a as is 85 FXR from Harley Heaven. Got it for under $10k.

Same model as mine...I have the 86 but they are identical.  I have the manual diagrams somewhere

Nice bike 👍, breakers do fail, but sometimes they are doing what they supposed to because of a short, instead of hitting the start button with ignition on try jumping the solenoid pull terminal to the main positive beside it, if it starts easy it might just be a breaker, if you can round one up a factory service manual is bloody handy, you gotta search for them though, but pretty sure there are digital versions available online at various places.

what circuit is the black wire/blue crimp running, looks foriegn to the rest.

that is one sweet looking bike....tidy as

yonks ago i fitted a simple inexpensive aftermarket solenoid push button for such occasions that my old Evo wiring might not be up to it on a given day.....been handy a few times

The breaker pic posted is of another set up to find out the amps. Mine has had some elec upgrades, here is a pic of my set up. 

That needs a good tidy up, them crimp connectors are not ideal, aside from being an undesirable way of doing it if not done correctly they can and often do cause intermittent connection, your problem could well be right in front of you, not much we can do remotely, I would give them all a bit of a tug to see if any are loose then try to jump the start solenoid to see if that part of it works, basically working backwards towards that rat nest.

Thanks Hilly, just did the solenoid jump, started and ran fine, no brake light, indicators or horn. 

Thanks evo94, my 85 has the rubber boot on the back of the solenoid. Dont think there is a bolt on button for that.

bugger....sorry for bum steer cob :-/
