2 Din head unit flashes from day to night mode when rh indicator and brakes are on.

I think when the problem was happening with your indicator that was an earthing issue, sounds like that has been resolved with the earth strap.

It sounds like you already have enough load on the stop light circuit. If you have a resistor handy you can try putting it on the tail light.

Before you do that connect a voltmeter to one of the tail lights. For ease it can be the tail light feed in the trailer plug. With you foot on the brakes what is the reading?

Edit... the resistor fitted to the tail lights is only for testing purposes. It will generate too much heat if left fitted when the park lights were tuned on.

Ah yes it will too...
I'll go check the voltage tomorrow. Thanks.

If you don't want to muck around with it and your tail and stop lights are working correctly, you can fit a relay to the tail light circuit to isolate it.

The easiest place to fit the relay would be in the passengers side kick panel. The harness for the tail lights runs through there. The tail light wire is a blue with a black trace.

Thanks Rodney. I really appreciate your input. I'm just trying madly to get my camper finished for this weekend. Just gotta fit up this volt and amp gauge with the shunt then I'm onto this if I have time before this weekend.

Hi Mudski, I bet you've got a reverse camera linked into your double din unit?

Display cuts out occasionally
•If the screen goes black when you apply brakes or indicator, this is related to the reverse camera trigger wire cause by small voltage jumping to the trigger wire from the brake light or indicator.
- A common inline diode such as Part#: 1N4001 - 1N4007 will need to be added between the trigger wire and the reverse light positive. Ensure the diode is around the correct way.

Its an easy job and I have one of these diodes spare which you can have if this is your problem. Save pissing around testing earths etc. My dig options double din system did this until I put the diode in. The diode fits in the live feed from the reverse light to the din unit (easiest place to fit is in the back near the reverse light)

Cheers
Mark

Sorry for the late reply.... yes I do have a reverse camera. The display has cut out maybe five times in the 2 years it's been in. Its the issue of the night mode coming on when i apply the brakes. I think I have some diodes already when Yendor guided me through how to make the angle eyes go off when the headlights are turned on. Little black thing with a silver stripe.
But I can't see how this is related to the issue at hand. Unless it is...
thanks.

O.k I finally got out to do this test. 12.2v is the reading with tail lights on, 12.1v with the brake applied. What does this tell you?

run a new ground to the body of the car, then if your still having the problems get your multimeter out and check how good the ground is through the illumination wire on the OEM harness.
