Help replacing an OLD isolator
So I am going to assume my isolator is broken (judging by how old it is) and NOT that it was wired wrong. Although it does seem to be wired differently than the instructions I see for new ones. Fo...

Only armageddon prevention protection should be placed in between an alternator and the chassis battery. The safest protection as far as reliability is concerned is a fusible link. Fuses can corrode, breakers can break, and switches are controlled by mistake makers.
In my designs I am so touchy about this that I insist on a straight run from alternator output stud direct to battery positive. A 2nd cable from battery positive gets distributed after a very short run. The manifold at that point gets branch over current protection devices.
Why people gnaw fingernails to the quick over the supposedly "exposed therefore vulnerable" alternator to chassis battery wire is beyond me. The circuit is protected by a fusible link. Want tough high temperature wire? Use XL cross linked polyolefin insulated wire. Insulation is extra hard and extreme temperature resistant. Black nylon spiral wrap can be applied over the cross link wire. Then, it would take pressing directly against an exhaust manifold or hammer and chisel to compromise its integrity.
Ill furnish a link below in another response to a relay that shames the reliability of a metal an relay if an individual insists on using a control wire or switch.
