Only needs two wires, run a 40 amp cable from the large terminal on the alternator marked +, direct to the positive terminal on the battery or to the battery supply feed to the starter (which ever is easier). Then run a wire from the terminal marked 'ind' to a 5watt bulb, other side of the bulb needs to be wired to an ignition live feed. That's makes it the charge indication light. You need to fit this light, without it the alternator will not charge!!!! Light will come on when you switch the ignition on, and go out when the engine is started. Put a volt meter across the battery, should get a reading of 13.5 to 14.5 volts with engine running. Good Luck.

Can i put the ground wire direct from light to frameto keep it burning out?


Most cars have neutral / negative earth where the neutral / negative is wired direct to the body / chassis of the car. I cant see how wiring the negative side of a lamp direct to the body will stop it from burning out as the wiring harness already there will ultimately be connected to the body anyway. If a globe keeps popping, I would suggest it may be the wrong wattage and getting too hot ?

Wiring an alternator to a kit car


take the alternator to an auto electrician and have him explain which terminals you use. Ask him if it is internally regulated or needs an external regulator as there are marked differences as to how it is wired up.

How doi install a radio after the original has been stolen and wires ripped out


You will need to buy an install kit even if they did. The back of new Radio's don't have anything but a plug to connect to. So the install kit will be needed to hookup the four {or just two depending on it's already installed options} speakers, the power, and ground. Plus the Antenna cable. They will all be color coded.

For example:

I'm trying to find out how many wires connect on the alternator for a 1994 Geo Metro, I have the wires plugged into the alternator and then have a black and yellow, black and a green and black wire and I'm...


There are usually only 3 wires to an alternator.
The heavy red power output, a light field input, and the chassis ground.

There are about 20 different types of Geo Metro alternators, so I can't be sure, but I doubt your extra wire are for the alternator. Often a wiring harness will have all the possible wires, whether they are needed or not, such as AC, etc. Look at one in a used car lot or salvage yard.

I just finished rebuilding my truck engine and will like to test it before installing back in the truck. I know how to get the starter going, but I don't know how to wire the coil, distributor, alternator...


To start the engine you need a+ feed from the battery to the + side of the coil[this acts as an ignition live,to be disconnected when not testing the engine ]Next you need a heavy + feed directly from the starter to the battery[use good heavy cable]Also a good heavy earth lead from the battery negative to the engine block[jump leads work great]Connect the distributor contact breaker wire to the coil - side.To start take a live+ wire from the starter + to the "pull in" terminal of the starter[this is a male spade connector and the lightest terminal on the solenoid.when you connect the starter to the battery + the engine should turn over,Check for a spark using an old plug earthed to the block,add some fuel and listen to that baby run.

How do i polarize alternator after new regulator saab9000 1989?


You dont. Alternators DO NOT require polarisation as they can only be fitted to vehicles that are wired as NEGATIVE EARTH. If you have replaced the Alt, reconnect the wiring, reconnect the battery - Positive lead first then the negative lead, then start the motor !! Using multimeter, check the charge rate at the battery. It should be around 13.8 volts. The charge rate SHOULD NOT go above 14.7 volts and if it does, turn the motor off immediately and recheck the connections, especially any battery voltage sensing wires. if nothing appears to be wrong, contact an auto electrician and have them check things out. I have known faulty regulators, even in new Alternators..

Hi I am Vortash the battery light is an indicator to if the Alternator is charging or not .. if the light is on it is saying that it isn't , check the plug and wire connections to the alternator check your earth strap from your negative side of the battery to earth or if it is a continental positive earth car check the + side is attched to the earth securely and cleanly .. check the output from the alternator you should be gettinfg approx 13.5 to 14 .5 volts DC if not switch to ac if you get a reading the rectifier has gone and will need replacing ..( most of the modern alternators come with new brushes attached to a rectifier as a single module ) Check the fan belt tension slipping belt can cause bad charge rate and bring the light on .if you are finding the car is becoming difficult to start the battery going low the fault is realy dead to rights a charging fault.. Hope this helps Vortash
