How about each fan separately. When the AC is on, just have one on all the time, and the other cycles. You can also set the thermostats to engage at slightly different temps, so they are not kicking on at the same time.Well......that didn't take long. Already burned up the 50A circuit breaker to the fans. I used the wire they supplied with the kit to feed the breaker, burned the terminal out of it. Mucho bigger wire with soldered heavy gauge copper ends will hopefully stop that, and like I said above fans always on when the A/C is on will stop the repetitive high startup amp load.
Drove it nine miles home at 2500 rpm with no fans, about 98 degrees today, ran 210. Getting out of town was a bit sketchy, turned the engine off at every red light 😆
