We installed new 20" bars. Wiring looks good, new battery, new fuses and new quick valve. Now we have no power. Not sure where to start troubleshooting.

 

What bike? What year? How about some more info??

 

2011 Dyna Wide Glide

 

Wiring not reinstalled properly. You will need to disassemble and find your problem.

 

You know new batteries usually need a charge. Did you check the charge?

 

Did you remove or pop the maxi fuse?

 

Check voltage at the coil...if you have less than battery voltage at the coil.... check the run/off switch circuit...

 

My gut is telling me throttle cable not adjusted right.

 

You might have pinched a wire and grounded it to the frame. That happened to me this past week putting
new Dominator mini-apes on my FXDL. Found the pinch, fixed why it pinched, fixed the pinch, re-assembled,
all is well.

 

In my experience, pinched wires would allow bike to start and then blow a fuse. I would pull tank and look at electrical connectors that you had to add extended wires for the longer bars. I bet you put a wire in the wrong numbered pin. Take a look and see if your wire color codes match up on both sides of connector. Are turn signals, horn, lights working?
