So assuming one has an unmodified car, what's the key-out, "off" current on these? I've got a 72 4 which doesn't even have a radio. I could certainly go through the wiring diagrams and determine this for myself if this is potentially anything other than zero, but there's a good chance I'll miss something quirky, so I'm asking the experts.
If turning the car off brings the background current to zero, then there's no need for an isolator obviously. |
