Title: Wiring for Rally Navigation - Advise Required
Post by: SparkMark on July 23, 2019, 07:21:28 pm
Hey guys,

Wanted to check in with you guys on how you wire up your Nav stuff. The reason that I ask is that I have had an issue with my RNS GFX unit, that froze up.
After a reset it froze up again. I had previously ridden maybe 10 hours with no issues.

Tony (from RNS) thinks that it may be because of fluctuating voltage and has recommend that I take power from the headlight rather than the battery.
I don't quite understand that, as the voltage also fluctuates at the lights.

My setup is as follows:

Separate loom ... from battery with a 10A main fuse.
That goes into a fuse box, that has 4 fuses (2A each)
From there into 4 switches and then onto the 4 things that I'm powering (RNS GFX, RNS Trip Master, Roadbook, Roadbook light)

I get 14.2v at the battery when the bike is running and 14.2v at the fuses.

- Does anyone have a separate voltage regulator (e.g buck / boost unit) installed for the Nav stuff ?
- Anyone run into the same thing with their GFX unit ?
- Any other thoughts ?

I notice on the rally bikes, there are no switches ... and its powered when the bike is on. Perhaps I should get rid of the switches and do the same ?

Had mine wired the same on RNS stuff. On 2013 KTM 450 No problems on 3 Amageza.s. Check your bike regulator.

I had weird issues until I ran a dedicated earth wire to the tower.  Direct from the negative pole on the battery.

Regulator is good.

I run a direct earth wire from the battery and I have an extra one to the frame as well, just in case.

In that case, connect a small volt meter on the tower that will get fed from the positive and neg lines so that you can see any fluctuations.
