Checking power to the starter. Battery is connected and key/ignition is on at the first position. I have power to the big black wire. But the big red wire and the smaller one that clips to the solenoid (yellow one?)are dead. My 12 voltage check light does not come on. What makes power to those two wires? Does the car need to be running to light them up? Trying to figure out why some of my wiring melted. Thanks for the help.

That is what makes the engine crank. The smaller red wire should be connected to the same stud as the big heavy black wire. The red wire comes from the alternator and is used to charge the battery. It won't have power on it unless the engine is running. Clay |

The small red wire will be live if the battery is connected. (IMG:style_emoticons/default/smile.gif)
One thing you want to check is all the grommets, where the wires goes through the metal. Without the proper grommets the sharp metal hole can cut into the wire causing a big short. Check the wire itself, where it goes through the metal and confirm that the plastic covering is not cut. |

Thanks Clay and Mark.
I have been having distributor/points issues (melting points wire) and had the wrong wires connected to the coil. I had the condenser wire to the + terminal instead of to the - side. I think(?) when I get the wires in the right place that should get me power to the yellow wire at the solenoid. Maybe? I hope. |

I am fairly good with electrical things, but I don't get how the alternator can have power on the charge terminal if it isn't hooked to the connection on the starter where the battery cable is hooked. Or are you assuming they are already hooked up correctly? Clay |
