This is the way it's done:
If you have a 150-amp alternator you choose a 200+ amp rated smart solenoid. I would trust a Blue Seas brand for this. Secondly, you must construct a bypass circuit with switch that can be closed in case of component failure.
Smart solenoids do not need a control on/off wire run to the dash.
I would not advise doing such a modification on a vehicle that has it's alternator's voltage regularor as part of the main ECU computer.
You can also do an alternative:
Mount a 3/8" stud terminal block near the engine.
Remove power wire from alternator, change the ring terminal to fit the terminal block stud.
Connect 2nd wire that runs to house batteries. I use 4 gauge or larger.
Make up a new wire that runs between alternator and new terminal block stud
Also 4 gauge. Most RV's I see have too small of wire running to the house batteries.
Regardless I srill recommend a Blue Seas smart solenoid.
