hi guys just installed a big block in my 73 cuda with an msd ready to run and a mini starter,so i got rid of the relay and have wired my 3 wire altenator up corectly,everything is wired as factory,car cranks over fine,but when it goes back to run it loses all power(checked start and run modes on the ignition with a multimeter)power in start mode and no power when ignition goes back to run............how do i get constant power in run mode......what colour wire..what do i have to do?????????
