Switching to the solenoid type Andy is talking about is a great way to go . You don't have the voltage drop from the diodes .

A hot wire on a correctly working alternator should not have much current draw when not running .

Just got back from dinner and read the sheet on the 1315-200. Looks like I could tie the chassis bat and alt out to the main terminal and the aux bat to the other terminal. It sounds like it will tie the banks together when either one reaches 13.2 volts. If that is the case then I wouldn’t have to use the aux switch to keep the chassis batteries charged when on shore power. It sounds like a win on both fronts. Is this what your using in your bus Andy?

I installed this a while ago, but have been busy since. BMC people might like to know that this eliminates the need to combine your batteries when parked. I didn’t use the combiner function in the 1315-200, instead I retained the original system. This also solves the issue on having bat + visible to the alternator output if you switch to a 28si alternator. Thanks for the recommendation Andy. Both battery banks were rock solid today during a cruise around town.
