2009 Harley-Davidson FLHX: sudden loss of power

Filed Apr 26, 2016 · Electrical · 37,415 miles · FL

The throttle by wire failed while riding. I had a total loss of power and nearly caused an accident from behind. The dealer blamed corrosion on the circuit board of the induction module. Coating the connector is a temporary fix. After the 3rd failure I had it towed and had a new induction module installed. I spent $450 fixing a known problem with a wide range of the most popular hd motorcycles.

While riding down the I 65 south, I attempted to pass a 18 wheeler on the left. As I did I noticed the car in front swerve into my lane and I tried to throttle to get over and I lost power nearly slamming into the other car. Yesterday as I pulled out to merge onto the hiway I again lost throttle(power) and had to swearve to avoid being hit by on coming traffic.

On acceleration from a stop the engine loses power and goes into an idle mode. This event also occurs when you're accelerating up to road speed and occurs without any warning, including situations where you're entering into an intersection and potentially in the path of other vehicles - in normal situations, you have plenty of time to have a safe distance to clear the intersection. When engine goes into idle you're basically without the ability to move off the road safely without potential for collision. The latest situation occurred on 7/3/2013 while I was passing a vehicle and accelerating to 70 MPH, with a passenger on the bike. The engine lost power and went into idle at 2000 RPM without the ability to decelerate or accelerate. I was trapped abreast of the vehicle I was passing - if oncoming traffic was in close proximity, I could have lost any ability to take actions to get back into my proper lane of traffic to avoid a conflict.

The wiring connector at the throttle position sensor/servo is getting a bad connection due to the routing of the wire harnes and the extreme pressure being put on the pins inside due to the wires being pulled to tight. The pins wear from vibration and pressure cause the 5 volt signal to diminish causing the computer to go into limp mode. I was going up i65 north of montgomery in the center lane. The bike went into limp mode losing all power almost causing me to get by vehicles behind me. This issue is a simple fix to reroute wiring over top of throttle body to connection point. This is a life threatening problem.
