Won't start off engine battery

Alright my motorhome won't start off the engine battery but starts when I switch it over to the house batteries. I have had the battery tested and it is good, so am I looking at a bad altenator?

Have you checked all the connections from the chassis battery to the starter?

Have you had a high rate discharge test done?

Place an external battery charger on it over night, see if it starts on a fully charged battery. but your coach should charge the chassis battery too, does it ?

If you get it started, run it see if the alternator charges the chassis battery.
