Relay 2 is switched by the 12V power switch in the control panel above the door. This activates the system and supplies power to the step, doorway light and frost protection valve for the Truma. Relay 1 is switched by the main switch on the front panel. I knew too, that 12V power from the batteries was getting to the back of the EBL - but the habitation 12V would not switch on. I guess it's a call to Udo Lang at Schaudt in the morning unless a Funster can come up with the answer (which I hope is not a new EBL!).Īs I mentioned before, I was confident that all the work I had done was OK. I had to move the EBL forward and up in order to run the new cable but I was careful - no sharp knocks. I know there is 12V to the EBL from the new batteries as I can measure 12.7V at the rear EBL terminals (same as the rest voltage of the new batteries). I have tried working the switch a few times resetting the 12V panel switch plugging in to EHU (the charging routine works as the battery voltage goes up to over 14V). About an hour ago I finished everything, switched on the main switch on the EBL -NOTHING! Not even the sound of the main relay switching in.
The EBL has been shut down for about a week whilst I have been carrying out the work. At this point, there is no fuse in the isolating holder and the solar panel is not supplying power. This is not to protect anything - merely to allow me to isolate the solar panel for work on the batteries (the regulator is fused at the EBL in any case). I have also taken the opportunity to fit a fuse in the +ve feed from the solar panel into the LR1218 regulator. I am confident that the new cabling has been done correctly and I am confident that I have installed 2 x 90 Ah Varta batteries correctly. Just finished running an additional cable to the EBL99 and fitted two new batteries (having convinced myself that the previous ones were on their way out).
