I have a 2007 Softail custom and have lost blinker and the horn checked fuses and all wirering possible cannot find a problem any idea's

A 1992 Heritage doesn't have fuses, they have circuit breakers from the factory. A circuit breaker is looks like a small metal container that is about about a half inch tall and wide and about an inch long. It works like a fuse in that execessive current will trip the circuit breaker just like the ones in your house but as soon as the bi-metal strip inside of it cools, it will reset itself until the next time the current level is exceeded. The current level is determined by the currrent handling capability of the wire in the circuit it is controlling.

Now, the Heritage was notorious of blowing the filaments in the rear tail light bulb. Have you tried a new bulb in it. If that's not what it is, you'll need a test light or a DVOM (digital volt ohm meter) and a schematic to trace out the problem.

The horn is probably not on the same circuit as the tail light. Use the test light or DVOM to check for voltage at the plug on the horn. It's probably got a bad ground or just the horn itself is bad.

Good Luck

Your turn signals (but not your running lights), horn and a few other things are on the "accessories" fuse in your electrical circuit, I think. If the fuse is not blown, I would guess that you have a bad connection in the power lead for that circuit. I'm not sure of what I'm going to say here because I don't work on the newer bikes but in the older bikes, the "orange" colored wires carried the battery voltage to the individual components much like "red" wires used to do in most DC circuits. I'd look for a bad connection in a plug somewhere. I hope this helps but like I said, I don't know a lot about the newer bikes. I mostly work on the older bikes that the dealers will not work on any longer.

Good Luck

SOURCE: Fuse keeps blowing as soon as my 2000 Ultra is

Check the wiring under the handlebar assembly that controls that side, sometimes if this is taken apart for mod, a wire get pinched under the assembly. Check both sides while your at it. I would put a fuse in and unplug all the connectors, with the bike on, start connecting the connectors back and the fuse should blow, then you know exactly which system your working with. Check ALL the wiring in that system, I bet its a pinched wire up in the handle bars.

Let me know what happens please.
