IS dash with no power

[AussieValk]

I was wiring in a new accessory socket and was using the power from the acc side as I want it to be powered up without the bike running. All was going well, located supply and tapped into it then noticed after some time (15 mins) that I had left the key switched to Acc, but there was nothing on the dash, no lights or symbols, nothing. Switched to main power and had the fuel gauge only, still no radio or cb. I've checked all the fuses, wires and connectors that I had previously touched to make sure nothing was loose, but still no power. It looks like I've killed the whole radio circuit. Battery is good as it's brand new last week. I'm stumped now!

I've had a search in here but can't find anything relevant.

Anyone have any ideas?

click on Interstate and follow from the battery to the point where you lose power.

I had a similar problem on my Interstate but it was caused by moisture ingress in a hidden connector within the main wiring harness.
The problem is that this splice plug is located below and in front of the battery box. In a place that is subject to rear tire splash. It is protected under one layer of harness tape. The tape also hides it from casual view. The hidden connector looks like a square block taped inside the main wiring harness.

I fixed mine by removing the connector and splicing the wires together.
When the connector is severely corroded and there were two options:
replace the entire wiring harness or
cut out the connector and splice the wires together.
The connector is part of the main wiring harness and can't be replaced.

 It is located above the swing arm just below the battery box.


My display would cut out occasionally and it was really annoying. The only thing that worked was the fuel gauge.

I know of three or four other interstates that have encountered the same problem. As our bikes get older others will  encounter the same problem.

I think while you were trying to install your accessory and moving wires around you likely have disturbed something in a connector . You can fix this with a little patience and multimeter.  There is a wiring diagram for Interstates on this site.

I have a repair document for removing the hidden splice block that I can send you but that might not be the problem.

Thanks for the input.  I had considered that hidden connector but hadn't been in the wet for a while so it probably wasn't that. (might be someday though)

After I slept on the problem, I went back to the beginning testing for power again. It appears that I either missed a fuse or it blew again somehow. All power back after replacing the fuse. The upside is that I am now more familiar with the circuitry of the bike. All a benefit if something goes wrong on the side of the road.

"a hidden connector within the main wiring harness", You didn't  happen to snap a pic of this connector did you??

I'm overseas and don't have any bandwidth. I'll be home next week and anyone who wants a copy of the hidden splice word document can PM with your email address. There are pictures along with instructions.
Like I said one day you might need it if your LCD ,radio, CB and other stuff quit working. If you notice when your driving in rain that your dash quits then the hidden connector is likely the culprit.

I get a few weeks R&R with and then head back until mid May. Just in time to get back into the riding season.

Yes that is the connector I'm referring to. The following are routed through the connector (that I'm aware of):
LDC display;
Radio/ CB;
Stop Lights;
Clutch Lever Switch;
Side Stand Switch;
Neutral Switch;
Alternator turn on and voltage sensor wire;
Bank angle sensor and relay; and
General grounds

So you can see when that connector begins to corrode a whole host of electrical gremlins will take hold. Minor surgery on connector (removing it and properly splicing the wires together) is the cure. Unless you want to replace the entire wiring harness.
