NEWS FLASH While it has been implied that FanZilla doesn't "relieve" the load to the car's main power relay THE FACT IS The Fans DO NOT RUN THROUGH the car's Main Ignition Switched Power Relay. Hence, the Main Power Relay doesn't need to be "relieved". Further, in nearly 20 years Rob Grady is hard pressed to remember a single instance when he's had to replace a MAIN Power relay. ( It is important to understand : The Main Ign Switched Power Relay is NOT the same as the cooling fan relay. ) FanZilla can run the fans even with the engine off and the key removed. "Will my stock D's fans run with the ign off ?" No Only the FanZilla system controller can do this. Clearly, this was intended in the original design of the car. The DeLorean has a sticker on the fan shroud alerting you to this. Intelligent Fan system control was accommodated in the car's original wiring but not implemented in production. There were many things DMC just didn't get to do. Imagine what they would have done if they were still around today ? SCHEMATIC ERROR The complete schematic of the car is correct relative to the fan wiring. The Single page break out schematic is wrong. One final note: When both Cooling Fans switch on and off together a HUGE spike is created on the power grid. This is cut in half with FanZilla's sequenced cycling. WARNING TO ALL OWNERS The Idea of removing one fan from service to reduce the electrical load & spike is an accident waiting to happen. Failure of the remaining fan would not be pretty. Operation on hot days with a single fan WILL run the engine hotter than it needs to be. Not wise. Bob Zilla
