how do you connect the wire from the alternater to the starter?
The ignition wire in a Nissan 350z is black and red. The starter wire is white/red and the second starter wire is white/green.
The Chevy starter does not have a ground wire, the starter grounds through the starter casing.
Starter solenoid is sticking. Replace it.
on average you need to fuel an 18 wheeler once a day
It is the ignition wire. The purple wire goes to the small stud on starter.
Are you referring to the battery wire that goes to the starter? If so replace the wire. By disconnecting it and follow wire to the starter and replace. Reconnect battery and your done.
why would my starter wire burn, going from starter to battery
18 wheeler
The starter needs a large wire from the battery and a wire from the starter switch. These are connected to the solenoid that is attached to the starter.
Jump the starter solenoid Take jumper wire from Battery + to trigger wire to starter (mounted on top of starter)
