Disable alternator charging of house battery
Hi everyone, Does any of you have any experience in how to install and wire a manual switch to disable alternator charging of the house battery via a latching relay? I have a Trombetta Latching Rel...

That is not a latching relay which is a different design. Install a cab switch to supply 12V to activate as needed and eliminate the delay relay, You can reuse the ignition wire but connect the switch to the house battery because the chassis battery may not be able to engage the 684 relay when it's discharged, hence no emergency start. Of course you have to remember to turn off the new switch except for emergency start.
