You also should use at least 10 gauge wire to wire the regulator, for optimal performance.

Yup Same instructions i got,,you have to read between the lines to realize what he's talking about.

The POS needs to be connected to a 12 volt IGNITION source. NOT constant battery, it must only have power when the vehicle is running.

to me, the instructions are crystal clear.

What you have done with the relay is created an ignition source. If you are capable of locating a suitable ignition source (hot with key on, not hot with key off) then you shouldn't need a relay.

Unless the issue is that the stock ignition source is not capable of providing the amperage necessary to operate the alt. Then I could see the need for the relay.

This is why the relay is used,you don't want to overload the circut.Direct power from the battery is what actually feeds the power to the regulator the relay just provides a switch.You could use an open spot on the fuse panel but it is simpliar to just use the relay.

The draw back of hooking it up to the ignition on to the ignition source is that ,a/c ,turn signals, flashers,power windows all vary the voltage ,which in turns will vary the out put voltage of the alt.You get a more reliable and steady voltage from the alt or battery directly.It doesn't need amperage to work it just reads the voltage.

I believe he was using an open spot on the fuse panel but believe it or not the voltage varies too much at the fuse panel.Which will cause the alt voltage to jump all over the place.

That what I did, I hooked mine up to the fuse panel Ignition source and if you use the windows,A/C,Defrosters or anything that uses power from the fuse panel it start jumping voltage and won't level out.

did you guys figure it out?

 

[RHoughton1 10+ year member]

Yes,,,,, he needed to put a relay on the positive side of the voltage regulator,instead of using an ignition source on the fuse block.

Thank you. That makes perfect sense now.
