original owner. I was riding the bike at slow speed close to home. The bike quit. There is no sign of electric power going to anything, Nothiing to the instrument lights, headlight, starter, turn indicators, etc. The fuses look fine (is one a spare?). No previous trouble after 20,000 miles of laid back riding. What are the most likely things to check on a TW200 after fuses that look fine. Could a fuse look perfect and still be bad? Thanks in advance for any assistance.

Welcome to the forum!! Where are you from?

I would check and clean the connections at the battery and the ground. Do you have a voltmeter? How many volts does it show for the battery?

Thanks for the quick feed back I replaced the fuses even though the originals tested good. Battery has a charge (the motor started normally before the trouble). I disassembled the battery posts, wire brushed, touch of grease, reassmbled. I put a lead on the negative post and the other on the frame, bypassing the ground wire and the meter noticed that so doesn't that mean a signal from the post through the frame to the ground wire connection on the frame back to the negative post? Bike is still electrically dead. What next?

I'm in Grosse Point Park Michigan. I generally ride the Tdub from there to historic fort wayne staying close to the Detroit river. Stopping places likeThree mile park, Angel Park, Belle Isle Park, Riiver Walk, Joe Louis, several boat ramps, fishing spots, etc. Then scattered along the way are graveled areas where I do balance practice, Mostly ultra slow ride in straight lines or circles. Or I ride the front wheel into a pot hole, stop, balance, climb out without putting a foot down, etc. May be I care more about the skills than just riding around. Up on the farm is a klx300r bought used. A bit large for the trail riding I do but you ride what you got. The Tdub is an excellent excellent bike for balance practice. I practice on gravel because it lubricates the front tire so less front tire wear sawing the forks side to side to keep the bike up. Balance and muscle memory manage lean and traction. Thanks again for the assistance.

Check every connection on the bike, pay close attention to the connectors behind the headlight.
I can do some disassembly and wiggle everything. What ever the problem it is a wire or device that can stop all power to everything. There would be a limited number of things that can do that. Does anyone know where I can find an electrical diagram? 2008 bike.

Maybe a dumb suggestion, but is the battery okay?

I tested the battery, it's fine. Somewhere in the electric system is a wire or componant that's bad and it is something that can block all electricity from going to everything that lights up and the starter. The nearest bike repair place is 20 miles and I don't have a trailer at hand. With winter cominng on I'm missing some prescious riding days although I do short practices even with snow on the ground.

Thank you, looks promising and seems like that could create the total blackout I'm seeing. I'll go out and check for that.

I inspected the key switch mechanism. It looks like new. All the wires are well attached to the plastic holder. Judging by the guage of the wires under the key, do theyyy power a solonoid switch that has to work to provide power to the bike?

Forget the battery, the bike will run with no battery. Its in the ignition on/off circuit or a bad stator, etc. Think about the options on a problem like this.
No crank (that depends on battery); no run with kick or coast start (this depends on key, kill, and other electrical components); no lights (could be battery, but should glow if bike running), etc. etc. The solution is simple, its just not evident. Tom
