Hello everyone, lurker on here for awhile. This site has helped me many a times after reading various threads. Unfortunately this time I’m having a problem in which I can’t find an answer.

I own a 2002 Ultra Classic. Last Friday morning I washed the bike (It was a fairly thorough wash so I fear moisture may be an issue) and dried it off. A few hours later I got on and went to pick my fiancé up from getting her car serviced.The bike ran perfectly fine for the 20-30 minute ride there and back.

Fast forward a couple hours later and we go to pick her car up, I start it and notice I have no neutral light. As I take it out of the driveway I notice all of my gauges except for my speedometer aren’t working. I immediately went home. Upon inspection my headlights, passing lamps, and front and rear fender tip lights are not working. Aside from these things everything else works fine. Radio, brake lights, etc.The bike starts and runs fine.

So to review what isn’t working: Neutral Light Indicator, All Gauges Except Speedo, Front Headlight and Passing Lamps, and Front and Rear Fender Tip Lights.

I removed the fairing, as well as under the seat, to look for frayed wires and/or loose connections. Nothing stood out except for a broken ground to the triple tree towards the left side. I don’t have a multimeter but I have one of those light up testers. I tested all the fuses with the ignition ON... none are blown. But I’m getting no power to the LIGHTS or INSTRUMENTS fuse sockets.

I have a Clymer service manual and it has a wiring diagram for 2002 FLHT models, it’s not model specific to my bike unfortunately. I’m wondering if the ignition switch is bad or a wire or connection is loose leading to it? It’s been a few days and the problem still exists. So I’m not sure if water is the culprit, the timeliness of the wash and this problem is just suspect though. I did travel down a fairly bumpy road on the way back home after picking my fiancé up on the first trip.

As for things I’ve done to the bike recently: New battery in spring, HogTunes Tweeter Pod in May, new stater in June, and replaced the inner tank fuel lines in July.

I apologize for the wordy post, I just wanted to give you guys every detail I could. I’m happy to answer any other questions. I’m really trying to avoid taking it to the dealer as they are booked out and obviously the money. Thank you in advance, guys.

I am not an electrician, but my thoughts are if none of the fuses are blown then I would hunt for a bad ground.

Several electrical faults can keep the headlights from working:
  • Blown fuse.
  • No power to the circuit.
  • Bad ground.
  • Failed switch.
  • Bad multifunction switch.
  • Bad dimmer switch.
  • Open in the circuit.

I wonder if the OP even checked for CODES ? The procedure is a DTC sticky in the electrical section.

I must have posted this info 1000 times here already !!!

Sorry, amidst all of the details I forgot to include that. Bike isn’t throwing any codes.

I’ll look around again... The two grounds by the battery looked a little rusty. I’ll try and clean them up.

No power to the lights fuses ? Check the light relay under the seat, a rubber holder located in the frame behind the battery. Squirt some silicone spray around the holder to ease removal. The relays can be swapped around for tests.
Also a bad ignition switch would affect all electrics not just the lights.

Clymer isn't the best manual but better than no manual. Touring model Harleys have mostly identical wiring and the wire colors will match between models.

Ive actually read a forum about those relays causing issues with the gauges, I’ll be sure to check them out. I’ll report back with what I find out. Unfortunately leaving for vacation today so only have a limited time to work on the scoot.

As for the ignition switch, that’s kinda what I was thinking too, but still wanted to ask.

Just went out and switched them, problem solved as far as I can tell!

Hi I have found some people use a pressor washer to clean they bike. By using hi pressor can force water where it should not go eg: bearing and under fuel tanks also seats.. So you my need to check some the plugs do not have moister. Niemo
