Default alternator wiring question

On a '76 there is a clip with 2 wires, one is hot and the other is not. Where does the non-hot wire go? I have traced my battery drain down to this circuit. Thanks for your help.

One goes to the starter solonoid , and the other goes to the ignition switch , terminal 1 to the switch and terminal 2 to the starter solonoid , send me an e-mail I'll send you a diagram. Ron
PS it may go through a gauge or horn relay.

The non-hot wire becomes hot when the ignition is on and energizes the alternator field so it produces juice.

What would cause a drain on the ignition circuit with the key off? With the alternator unplugged all drain goes away. It appears that the hot wire is feeding through the other wire when hooked up and has something entergized. I have the clock unpluged as well as all interior lights and have zero current when the alternator is unplugged. This has me perplexed....

if your not worried about orginality, you can take your alternator to a alternator shop and have them install a self exciting voltage reugulator, then the 2 wire plug is not needed.
Problem solved

Bad diode(s) in the alternator. These serve as "one-way" valves but can let current flow both directions if internally shorted.

What are you using to check for current draw , hopefully not an LED testlight ?

The auto parts store does not test for shorted diodes, they will tell you it's good and it will put out juice even with a bad diode.
