Yes dash is working just no mph.im not get 12v where my speedo sensor connects under gas tank.any ideas? Its gone out before I replaced the sensor in the past.so I bought another one and it still didn't work .so I tested connection im not getting the 12v. Thanks
I couldn’t find an ‘03 wiring schematic but the 02 is likely very similar. When you are testing which plug are you checking? In this case the power at that point is on the B/W wire in the plug coming from the speedometer. The plug on the sensor will be dead.
If you go to Carlsalter.com you can download the ‘02 manual. The troubleshooting instructions are in section 7-35 and the wiring diagram is page 44.
There commonly is a B/R lead with 12 V to the sensor. You can check it at the sensor connector (with the bike on). If it's not 12 V, one or more contacts on the connector between the main and front harnesses are probably failing. That's fairly common on bikes of your vintage. There's probably a big connector with a sheath inside the left front cowl. But the location and details can vary and I don't have your manual. Look for the B/R and P leads. There's also a B/W ground lead but you'd have bigger problems if it was bad. You can also check at the cluster connector.
Thank you for your replies. I do have the manual. I've tested where speedo sensor gets connected with key on i get 3volts.tomorrow all gohead remove fairings to check all connectors maybe I over looked something. ..thanks again you guys.all let you guys oknow if find .
