Trik l Start question 2011 Expedition

[wbnjr]

I notice on our new to us Expedition that while on SP my house batteries would not charge. I was advised to install a Tiik l Start which would then solve my problem. I have done that but still find no power to start genset if coach has been stored for sometime. The house batteries still only seem to charge while engine running. What ami doing wrong. Thanks

The house batteries should absolutely be charging on shore power.
TrikLStart is for units like mine that the chassis batteries don't charge on shore power.

I'd make sure my batteries were wired correctly and also be looking at my inverter/charger.

Do you have a panel with your inverter that shows house battery state of charge?
