)* suitable for the FD19 and all rigs fitted with a JHub and the Redarc SBI, but without a BmPro Miniboost.
The proposed hack is:
Pulling the AUX connectors to the J35 at any point in the wiring loom ! (I was asked by Jayco if I ever tested this, but my answer was No, because I had installed the MiniBoost.
Benefits when driving in sunny conditions:
This hack fools the Jhub into determining that Solar is the only charge source available and hence it assesses it as the dominant charge source and switches it through all the time The output current that reaches the Leisure battery will only be subject to load and Solar charge conditions. No longer will it be subject to the redundant AUX input.
More tech info:
Jayco uses the high current Redarc SBI as their dominant AUX charge source, which makes the thinly wired AUX input to the J35 practically irrelevant. It obviously didn't do well enough on its own. Please be aware that the vastly dominant Redarc SBI borrows energy from your vehicle battery by paralleling it to the House battery for hours after charge sources have been removed. The Tablet will not show the Redarc's currents cause it doesn't know about them.
