Really? Been wiring cars for close to 25 years using this style set up. Never failed a NHRA tech inspection yet.
The alt line solenoid IS NOT a ford starter solenoid. It's a continuous duty relay. If the CD relay happened to lock closed, you are in no worse position than the folks that wire straight from the alt to battery positive post. The direct alt line passes tech every week and has for 40+ years.
One change to make if you are driving a street car. The line that energizes the Alt line CD relay should come from a switched/keyed source. The way it's wired in the above schematic will have a constant draw when the master power switch is in the on position. May run the battery down if you forget to switch off the master when parked for any duration of time.
Poison, HaHa, you could also use a Jeep solenoid... LOL :)
