1998 classic, i keep blowing the ignition system fuse why ?? trying to trouble shoot this have checked for loose wires none, to figure out this out it has happed when I'm at a traffic light, happed after fueling 3 seconds after starting
I do Not know of any Fuses on a Harley... the breaker will reset then break again??
You probably pinched the Grey, or white wire in the handlebar witch housing!! Start by Run/Off switch in both Run then Off, does it still pop the breaker?
What model "classic" do you have?
The owner's manual for my FLHTCUI says that the bike has circuit breakers and fuses. If you are having to replace the 15A fuse for the ignition because it is blown, then you are sure that you have a problem associated. But if you are tripping the circuit breaker then follow Racepres advice. (By the way, Racepres gives damn good advice.)
Below are a couple of pics from my 1998 Owner's Manual.

A fuse blows because something in the circuit is drawing too much current. Trace the circuit to find either a short circuit or a component that is drawing excessive current. If the handlebars have been changed that's a common source of electrical problems and something to look at first.
If it's a Heritage & you've had the tanks off recently, it's super easy to pinch wires re-installing them too.
I had the exact same issue with mine, turned out to be a short on one of the wires to the neutral light.
Grey wire comes from the ignition fuse, through a few connectors to the stop switch on the right controls.
When the stop switch is on, it powers the white/black wire, which powers the start switch, tees off and follows the grey back though the same connectors until it gets to the ignition or engine management harness, depending if it's carbed or EFI, if carbed, the w/bk wire powers the coil and ignition module, if EFI, it goes to the fuel pump relay and ecu.
So,, the grey goes to the right handle bar, the white/black returns power.
You could have a bad component or a short in a wire somewhere.
Look for problems where the harness bends when turning the bars, even though it's usually a break rather than a short in that area.
