Hello Forum,
     I just recently vector 300 w 5km Air cooled and am trying to desk test it before I install it in my sailboat.   I'm trying to determine how (if) I can use a ET-134 throttle controller instead of the rather large heavy one that Golden motors has for sailboats.

the et-134 has 48V input which I can get from batteries (switched and fused) and produces the  0-5V necessary Green-white throttle wire.  So far I haven't been able to get the motor to move.   What else is the controller expecting and on what wire? What signals are required to indicate reverse?   

In terms of shutting down the controller, is the e-lock (Orange wire) just a switch (closed/open circuit)? or is it expecting a signal of some sort?

Unfortunately the vector controllers don't have a proper schematic for the control wires that I have found so that I can plan my wiring harness.

Any help that anyone can provide would be useful.

I think this drop out works with the adapter.  it might need a little widening though.

Mark, the holes in the frame bracket are not threaded, they are just clearance holes for the M6 bolts that pass through them and then thread into the caliper mounting piece:



Please note that you only need to fabricate the section shown in blue (not the entire bracket) and it may have to be shaped differently to fit your particular frame:



Here's an example of a different bracket shape:



The most important thing to get right is the distance between the two 6mm mounting holes and the distance of each of these holes relative to the centre of your axle.
Please note that the centre of your 14mm diameter axle is likely to be at least 2mm lower than the one shown in the dropout above for a standard 10mm axle (unless you have already filed 2mm into the dropouts)

1. The light/horn connector should connect to the four unterminated wires coming from the junction block on the main Control Harness:



One of my Magic Pie Harnesses was equipped with a three pin connector which was presumably meant to connect directly to a battery voltage headlamp/horn unit (which I don't have) with a matching three pin connector.
The Red Lighting feed wire is connected to one of the outer pins, the Yellow Horn feed wire is connected to the middle pin and the two Black and Blue Ground wires are both connected to the remaining outer pin.

2. If your existing frame does not have mountings for a disc brake caliper you may be able to use a bolt on adapter kit to mount the caliper to your frame.
I have not tried any of these kits and I'm not sure how suitable they would be for your particular frame or for use with a 14mm diameter wheel axle.
If you have a steel frame (or forks) and want to try and fabricate some steel mounts to weld/braze onto your frame/forks, then these drawings may help:





3. I would use either electrical insulation tape or nylon zip ties to secure the brake cable (or hydraulic pipe) to the frame.

Hi Chuy andto the forum.

I don't have any experience with the EggRider display but I would expect the speed and odometer readings to both be effected equally by the wheel size/circumference settings.
As your mileage is reading too low, I suggest that you try increasing the wheel size/circumference until the speed and odometer readings matches the GPS speed and distance figures.

To measure your tyre's actual circumference do the following;
Make a chalk line on the ground and place your front wheel with the valve stem at the bottom of the wheel directly above the chalk line.
Roll the bike forward in a straight line one complete wheel revolution until the valve stem is again at the bottom of the wheel.

Make another chalk line directly below the valve and then measure the distance between the two chalk lines in mm.
(if you don't have a metric tape measure you can convert inches to mm by multiplying them by 25.4.)
Make sure that you measure the same wheel that the speed sensor is attached to. 

If entering the correct circumference does not cure the problem (i.e. the speed reads correctly compared to the GPS figures but the odometer does not) then you would need to enter the required offset value into the "ODO Offset" field to correct the odometer readings (make sure you also click the "Write" button to save it).

Example: If a 10 mile trip shows only 9.2 miles on the odometer, try entering an ODO offset value of 1.087 (10/9.2) and see if it sorts the odometer readings.
If this offset makes the odometer reading even lower, try entering a value of 0.92 instead (9.2/10).

Please let us know how you get on.
