My guru buddy had issues with auto combiners masking bad engine batteries where the newer combiner dis connects when starting  under auto so the engine start batteries true condition can be shown
Bob,

If you have adequate engine batteries, why in the world would you need any kind of auto combiner? My diesel tractor, several diesel cars only have one battery and do fine without a "spare" battery. Our fire trucks had two 8Ds for starting but also no spare.

To me, it's a case of the owner not doing any engine battery and related components maintenance so they use the boost switch to mask the shortcoming. Do it like Jimmy and maintain it then you will never have the need.

That's the point.  He no longer uses the auto combiner on starting designs that were the only ones available.

The new units on auto do not combine the batteries anymore.

That's we he installed on ours.

He has 17 years of customers and things evolve.

Our start batteries see less than one tenth of one percent discharge to start the coach so the "heavy lifting" is for perhaps two seconds, not enough to be noticeable.

Maybe so on your Detroit without a air intake
manifold heater. Probably not a bad idea to use the Boost switch on a cold day with the Cummins. If not just extra work for the alternator to bring back the chassis batteries.
