4agze supercharger not work

[Sprintn]

Yeh it worked when I connected one wire from the charger to the negative terminal, so is it not good to drive it like that? Could it be the relay?

Its not suggested, as it burnsout the clutches or something ( been a while since i done research on the charger ).

other then that i cant really help sorry, i run a microtech so is wired a little different to yours.

Oh ok fair enough thanks heaps mate

Yeah dont run it like that.

The factory way is one pin on the ecu (i cant tell you this as you never stated what model ecu/loom you are using) is an earth when the supercharger is activated (black yellow). This pin is used to trigger the relay which is powered by a simple 12v ignition wire hooked to it (black red).

The output side of the relay has a black yellow wire before the switch (from the supercharger clutch), and a brown earth wire as the output.

The way it works is when the ecu wants the s/c to work, the ecu earths the pin which activates the relay and pulls the black yellow wire on the supercharger clutch to ground.

Now you may think you can connect the supercharger clutch directly to the ecu, but this will put too much current through the ecu and probs melt some things.

for a diagram.
