Ok after replacing the controller with another one, I see the same symptoms, except the multimeter ohm reading throttle driving problem.

I could not make the wheel spin using the throttle signal, I checked the software currently running but I could not see anything wrong, after the first time I changed the battery settings from 48v to 36v and then I shutdown and start reading again but this time when I connect the usb to my laptop a strange tick sound comes out every second or so, then if I manually spin the wheel, it starts spinning and then stops and then spins again, here is some photos for what I replaced.

Hi Alan,

Thanks for your reply. Will check the brake handle sensors.It works properly before, but after an emergency stop it doesn’t work anymore, thus something with the brake switches sounds logic

Thanks Alan, I see it's on the first post now. GM sent me the wiring diagram for the controller, which is the same as every other diagram I've looked at. Unfortunately it's not quite right. They told me the throttle got its power from the red wire on the throttle plug, which goes to the white wire on the throttle loom (the one I got reattached) but it actually comes from the KSI plug on the controller and goes to the KSI plug on the throttle loom. They also told me every wire from the throttle had to be connected to the controller. Not sure why parking and brake need to be connected on a boat but they ho.
The electrician who connected it all up in the first place had the key switch connected to the KSI plug on the controller. Should have known it was wrong. He had one of the CN2 loom plugs connected to the CN1 loom. I can't remember which one but I knew that it wasn't right.

Any chance you know what SIF stands for ?

Just tried again and it is too big. I'll email it to you.

Hi Soetie andto the forum.

I suspect the "Eb5" is just a visual notification that the EBS is engaged due to a brake lever being stuck partially open, which can easily occur if you have plugged in the brake lever switch connector before the brake Bowden cables are physically connected to the levers and one of the levers is not fully released because the cable attachment pivot is preventing the lever from returning fully:



If the brake levers are definitely fully returned to the released position and you are still seeing the EbS notification, it could be due to a faulty brake switch or the wiring going to it.
Unplug both brake switch connectors and see if the EbS notification disappears. If it does, plug in the brake connectors one at a time to determine which one is causing the problem.
