Aux battery switch not working
On a 2018 Southwind 36P my chassis battery got low and I needed to use the Aux switch to start the RV. When pressed, the light does not come on, there is no relay click sound, and no power to the battery. I have checked the fuses in the power control module, in the cab and all coach fuses. I was able to start the RV by running jumper cables from the coach batteries to the chassis battery, but the aux switch would be much easier if I can get it working.
Any ideas ?
