Fuel flash code eight... Possible wiring issue? 1 Month, 2 Weeks ago  
Got the bike back from the dealer after the recall and the mechanic told me the wiring harness is a mess of dirty splices with electrical tape everywhere. I'm really not surprised. I paid $4k for this thing and I didn't expect anything on it to be in particularly good shape. Anyway, that was apparently an excuse for the dead fuel gauge and main headlight. Well, I'm getting flash code eight from the fuel light and my headlight is out. I'm going to avoid the knee jerk reaction of buying a new headlamp bulb and just poke around the wires until I find a shitty splice somewhere. I don't know much about the fuel level sender unit, other than that it costs $400. Is it possible that my problem with that is just a short circuit or something? Maybe a fuse? If I find out I can't fix it, I'm definitely going to raise a little hell up at the shop. They have a pretty good reputation and I'm sure they wouldn't sully it over $400. I'd rather it didn't come to that though, so is it possible that some time, effort, a bag of shrink wrap and a heat gun could clean things up and fix the issues? I'll let them off the hook, since they just tore my bike completely apart and put it back together in two days with one of their two mechanics on vacation the whole time, but I'm not thrilled about how it came back to me.

This is anecdotal. Skip it if you want:

Got the bike back with new bearings in the neck, swing arm and both wheels, high flow oil pump gear, piston rings, Speedstar stage IV clutch, new engine and transmission oil and filters, fuel filter, adjusted valves, brake pads, etc. The bike immediately felt about twice as powerful as it was before the recall was done. I guess I was getting a lot of blow-by before the rings. I can't imagine it being anything else. Anyway, the underwhelmed feeling I had before is now gone. I went ahead and replaced the side covers with Show Chrome units, since they were dented up and starting to rust out under the crap paint job. Progressive fork springs are on the way to keep my street sweeper fender I'll be getting when I can afford it from hitting the ground. It's just a matter of money now. Once I'm ready to spend the cash, the bike is getting SS Custom Cycles' street sweeper fenders, shark fin dualies, air ride and Kong bars. I've just survived long enough by now to know I need to spend the money on the basics first. A sweet looking ride that doesn't run or isn't safe is just a polished turd.

Yeah, I misspent my youth making junk cars run faster than most people would believe. I learned a few hard lessons along the way. I hope the Roadie turns out as nice as I have it envisioned in my head. I just don't know if I'm going to paint it flat black with red pinstriping or give it the Model T Ford with original paint look.

The 8 flashes is a self diagnostic signal that your fuel level sending meter is down you can take it off and test for resistance to determine if it is fried . As for the headlight there is a fuse to check ....Coug

Two questions:

Where's the Roadstar's fuse box?
What resistance am I looking for when I test the sending module?

The fuse box is under the left hand side cover(fuel pump side)15 amp I think.When removing the cover be aware that the left side and the right are held together with a clip nut and it is very prone to dive into the middle of the bike and disappear...


To test for resistance using your ohm testmeter, you have to remove the sending unit and with the float inside the tank in the normal empty position the reading should be between 140-143 ohms...in the normal full position should be 11-13 ohms......Coug

I had the cover off to avoid scratching it when I was beating the AIS taps out with a slide hammer. While I was in there, I checked the fuses. All good. I'm going to look around for a loose wire tomorrow, I guess. If I can't find anything, I'll test the line with a bulb I have left over from another bike. Haven't messed with the fuel gauge yet. I'll be pulling the tank off tomorrow to have a look around.
