Hello,
My uncle is having some issues with the speedometer on his 1999 Fatboy. Here's what I know.
While driving down the road sometimes the needle will get stuck, sometimes it will go to zero. Whenever either of these two things happen the odometer display goes away. It can stay this way for many miles. Normally happens when the bike is cold. We were doing some trouble shooting in the garage today and found that we could make the odometer blank out occasionally while revving the engine. This would happen whether we had the speed sensor plugged in or not. When the key is on and nothing is running there is approximately 13 volts at the orange wire and 11 at the green wire. I noticed that the odometer will blank out while the engine is cranking over to start (don't know if this is normal) and the green wire will drop to 8 volts. I don't notice this voltage drop when the odometer is blanking out while revving, but I may have missed it. The speed sensor is new. The bike has 12000 miles. He just purchased and installed a speedometer from a 2003 softail with 400 miles off of ebay and has the same issue. Any help would be greatly appreciated.
