Yes, there is a wrong way to make it if you don’t understand how it works.

Attaching to the alt stud WITH THE CORRECT alternator, won’t get the bulkhead or ammeter loads going through, except with engine off and if fans are still running.

ONCE AGAIN, WITH THE CORRECT ALTERNATOR OUTPUT RATE.

Anyway, get the bulkhead path bypassed it will get a better charging system STILL with the ammeter in line, as far ammeter is also in good conditions… checked/serviced after all these years of use and abuse.

STILL WITH A 500 AMPS ALTERNATOR.

(Amps are not pushed in by the power source but sucked out by the accesories. Power source just need to be able to provide them anytime)
