Tip & How-To about 2005 Audi A8

Alternator warning light stays on after the start.

Swap the wiring of the ignition switch for terminal 50 and 50b around. Now terminal 50b is switched on first to activate the alternator and the alternator warning lamp goes off during the start.

wire 253 holden boat motor starter alternator coil basic diagram

batter positive to one big terminal of the starter solenoid--large wire as in a car ( the other big terminal will have a wire from it going into the starter)
a wire from the start point of the ignition switch to the small terminal of the start solenoid .( This to energize the starter solenoid to start the engine.) a large wire ( 30 amp capacity ) from the positive terminal of the battery going to the BAT terminal of the alternator the plug in the back of the alternator will go to the battery light or ammeter.. wires from the start and run positions of the ignition switch to the coil. One to provide power when the starter is engaged and the other from the run position to provide power to keep the engine running
basic but it will work

1989 dodge 250 the red ignition wire is getting hot and melting in two when the key is turned to the run position

Blue wire to ignition switch,from alternator voltage regulator.( 12 volts ) ECU power wire, Red wire to battery terminal. Blue wire goes from alternator to the ignition switch. The voltage regulator senses the incoming voltage from the blue wire. ) it grounds the green field wire This energizes the alternator field, and the alternator begins to produce a charge and sends it to the battery via the main output wire. When the voltage regulator senses 14 volts from the blue field wire, it cuts the ground to the green field wire. Good-Day!

The engin will not turn over intermittently. I had the dealership check the batter, the starter and the alternator. All came out good. They could not get the car not to start so they could not fix it. I took it home and the next day it had the same problem. Sometimes if I keep trying or wiggle the ignition it will start. Currently it will not start. What do you think it is?

Try starting in Neutral instead of Park. If this works, the transmission range switch (sometimes called a neutral safety switch) is faulty in Park.

Next, you can try a remote start switch (available at auto parts stores) or a jumper wire to bypass the ignition switch. First make sure transmission is in park or neutral. You will be jumping from the battery positive terminal to the starter solenoid. The starter solenoid terminal has a black wire with a white stripe connected to it. (This terminal is visible just to the left of the automatic transmission dipstick tube.) Remove this wire and connect one end of the remote start switch wire (or jumper wire) to it. Connect the other end of the remote start switch wire to the battery positive terminal. Activate the remote start switch and see if the starter will crank. (If using a jumper wire, briefly touch the other end to the battery positive terminal and see if cranking will occur). If the starter works then you have a problem in the ignition switch, or starter cut-out relay.

The starter cut-out relay is located on the back of the driver's under dash fuse/relay box in the left wall kick panel. The ignition switch also has wire leads that plug into the back of this same fuse box. You can disconnect the wire leads and test the ignition switch with on ohm meter from this point.

how do you connect alternator wires to the starter

There is only one wire common to the alternator and starter and this is the main+ wire which goes from the alternator down to the main feed terminal of the starter solenoid from there it runs to the battery + terminal.If you are replacing the cable use one of the same diameter......
