Isn't that dangerous on the old wiring in our Z's? Just curious.

. A 1,000,000 amp alternator is fine in our cars. The car only draws what the device needs. Having more available amps allows you to run a stereo, fog lamps, radar detector, cell phone charger etc etc.

Don't you still need the voltage regulator replacement adapter to go this route?

I think that the GM alternators are typically run as "one wire" systems.  The S(ense) wire is just shorted to the B(attery) wire.  Edit - and the L(amp) wire.  All one wire.  So the alternator will produce current.

Other wires run through the VR.  Haven't really followed them out.  Best beware.

The GM SI alternators can be wired as one wire or three. The plug is there on all of them. Your choice.

That is true.  The adapter makes the wires at the alternator correct.  So you'd just need to get those right for the plug at the GM SI.

Some of the other high output alternators, like ZSpecialties' 140 amp unit, are "one-wire".  Still waiting for him to finish his web site.

Good to know.

I've heard it could over heat the old wiring. Not true I guess?

Amps are drawn, not pushed. The device uses the amount of energy it is designed for. The gauge of wire is designed for the amount of current being drawn by that circuit. All those amps just sit idle until drawn by a device. Think of it as having a reservoir of power available for more devices than was originally designed for the car.

Okay, makes sense. Thanks. As you can tell I usually stay away from "electrical".....

Afraid of it.

Another way to look at it is to liken it to a water hose: amperage is the diameter of the hose, whereas voltage is the pressure. You can't have a hose too big, but if you have too much pressure it can break the system.

Me too!

Invisible stuff that can kill you.

In this episode I go back and tidy up a bunch of loose ends on the 680g

 

 

I've been on my car for 5 years now and I still remember/find little things to correct,  sometimes 2 or three times but the benefit is that by the third time I'm pretty good at it ?.

In this episode I put a few finishing touches on the exterior of the 680g and some of them may be controversial.
