One last thought. The Cole-Hersey merge relay is a known source of issues. I believe that it is wired in parallel with the two outputs of the isolator. Have you removed it as a source of the voltage drop. The reason that I mention this is because it would be way cheaper to replace.
Also...If you are contemplating ever upgrading to Lithium batteries....you may want to look into an isolator that has a high amperage rating. My alternator can put out close to 300 amps and the batteries can take all that and more....but the isolator is rated for far less current than that. So, if the lithiums are run down and the engine is cranked, you could easily overload the isolator. Just a thought.
I found these guys who make solid state isolators, but did not buy one yet. Perfect Switch
bill.
