SR/F 12 volt supply
« on: August 22, 2019, 04:21:15 AM »

I have emailed support but no response yet.

Looking to install a permanent camera solution.

Camera requires a constant 12 volts and a key controlled 12 volts.

I found there is a SAE connector for 12 volt accessories (but haven't check if key controlled).

The SAE connector is key controlled. There is no Zero approved always on 12V source. If you're willing to risk things, you could connect to the 12v battery directly.

There appears to be a connector in the tank storage box just under the hinge.  If you remove the cover on it believe you are looking at an automotive style DLC (data link connector) which is used to connect a scan tool to the vehicle.  If it is, they usually have a 12 vdc power source to power the scan tool and it is usually always active.  You could try probing the connector for 12 volts. If it is the same shape as an automotive connector, there are plugs prewired to get the 12 volt power out available on the internet.  I just took a quick look at it at the dealer as I don't own an SR/F yet---but I will own that bike next week.

I finally got my SR/F and can confirm there is constant 12 volt power available at the DTC connector located in the front of the "tank" box.  I bought a OBD II power adapter wiring harness on Amazon that plugs into the DTC connector and provides a pigtail wire to connect your accessories to.  I wouldn't draw more than 3 amps on this circuit but it should be enough to power most of the devices (cameras, GPS, etc.) you would want to power anyway.  Be aware that the 12 volt battery is very small so you would need to be careful about leaving something on that is drawing power from it for an extended time.  Pretty sure there is no "run down" protection provided by Zero for the battery and hence the admonishment from Zero to not connect anything to it.  It is a Li-Ion battery so running it down could damage or destroy it.

On a brighter note, using the DTC connector for a power source is easy to reverse with no trace of a connection should something go wrong.

Awesome. Could you post a link to the harness you bought.

Also do you think the 12 volt battery gets charged by the bike when the main battery is charging.

Bought it on Amazon, appears well made

I dont know if the 12 volt is charged during charging the main pack but would assume it is.  The DC-DC converter would charge it when in operation.  Hook a voltmeter to the battery (via your new adapter) and see if the voltage changes under different charge scenarios.
