Progress on the Rans Fusion E-Bike build:

  

All of the new parts have arrived and the process of the E-Bike conversion has begun.

All of the parts that will be replaced have been removed with no surprises.

Grips
Brake Levers
Front Gear shifter
Rear Gear Shifter
Front Derailer (with the mid drive motor, there is no need for a triple front chain rings)
Pedals 
Crank Arms
Bottom Bracket 

The bicycle then was cleaned of any dirt and grease.  The Frame was in perfect condition.

A mock up install of the new part was done to check for motor/chain line alignment, cable routing options for speed sensor, gear shift sensor, wire harness route, display mounting, Electronic controller, Sram 9 speed shifter, new brake levels & throttle, male xt60 to Anderson connection extension to match motor to the batteries that I use on all of my E-Bike builds. 

It is super important to NOT have wiring or cable wires be pitched. The main wire from the motor to the wiring harness will run between the motor and the bottom bracket frame for a clean installation and to keep cable from snagging.  The rear shifter cable runs under the bottom bracket frame as well. So it is important to NOT let the motor press against the cable or wiring.  The Shift Cable stops keep the motor from twisting too high on the frame.  A quick pre install of the motor into the bottom bracket confirms that the shifting cable worked smoothly and the motor wire moved freely between the motor and the bottom bracket. 

Next Step was the test the motor and display to see if it would turn on. I connected all of the components, then connected the 48 10aph battery to the system.  I turned on the display an NOTHING.  


FAILURE.

Trouble Shooting
unplugged and re-plugged all connection.  - nothing
used a different battery - nothing
used the batteries on a other e-bike - yes the batteries work
plug the new display into another E-Bike - Yes, the display works fine. 

I was not able to test the "male xt60 to Anderson connection extension" maybe it is faulty, although it is new. I called the seller and they suggested sending everything back for them to troubleshoot and resolve the issue. It could be a faulty motor controller, or a component.  

BUT it could be a 'user error' .

We will soon find out!
