On the diod, the Cathod is marked with a silver ring ; solder the 2 inches red wire on it.
Then on the other side, the Anod, solder the 2 inches black wire ; at the other
xtremity of this wire, set the 6mm round pod.
Properly insolate the connections with thermoshaft.
2. Unmounting the fuse and relay stands.
First of all, disconnect the battery. Generally, it's a good idea to begin by the negative to prevent problems ;-)
Unscrew the lateral cover in order to access to the fuses socket.
Release the fuse and relay socket (2 screws for allen key 5).
Locate the ECU fuse. Warning : on Calif EV, it might be either the 5th or the 6th from the left. On my Calif EV, the wire between the ECU and the fuse is brown. On others, it can be green / white. Remove it from its stand.
Remove the ECU relay from its stand (here also, it might be the 5th or the 6th relay from the left side).
Release the relay stand applying a pressure on the small lock lever between these 2 modules and
Release the 6th fuse stand the same way.
The fuse stand and the relay stand unmounted:
3. Connecting the diod and put all the stuff back.
With the clip, connect the diod red wire to the wire between the ECU relay and the ECU fuse.
Put back the ECU fuse stand.
Put back the ECU relay stand on the ECU fuse stand.
Screw the fuse socket with the diod black wire to the ground.
Reconnect the battery.
Insert a 10A fuse on the ECU fuse stand.
Try to put back all the stuff you have been an expert to unmount up to here :-)))
The diod in place:
That's all, Folks ! With this protection your ECU should last all the life of your bike :-)
