Bike had been sitting for about a month. I always have a battery tender on the battery. Battery shows about 13.5 volts. Bike will not crank. Lights come on and I can feel the ignition relay clicking when I hit the start button. Question is it the ignition switch that needs to be cleaned or do you think it is another problem?
'03 Fatboy, carb. No recent work done on the bike. No work done on the switches, handlebars. Rode about a month ago, no problems, stopped and put the battery tender on as usual.
I have an 02 FLSTF and when I had issues w the ignition switch, nothing would work. No lights, no starter click, nothing. Its not a bad idea to clean the connectors on the switch and put some dielectric grease on them, but I dont think that is going to be your problem.
Corrosion on battery terminals (also ground at frame and hot lead at starter motor). It takes very little oxidation to cause what we "Evo" riders call the "dreaded click".
Also, if you haven't, take the starter solenoid end cap off, remove the plunger and clean the copper washer on the plunger and the two contacts inside. These contacts carry all 120 Amps the starter draws, and I'll bet yours are black and pitted by now. You can clean them up with fine sandpaper and polish them. Disconnect the battery first before working on the starter.
I think I found the problem. I checked the voltage across the battery poles. Registered about 13.5 volts. When I tested the battery while hitting the start button the voltage dropped to 5.5 volts. My guess right now is the battery is shot.
