    I hear that the most common reason for battery drain is the regulator? I've done most the rewiring on my cruiser, don't blow fuses, can't find a short or nuthin' but my batt will be dead if I leave it connected for a couple days of not running it. (red to Optima) Is there an easy home brew test for this? btw it's converted to a one wire chevy alt. internal reg.

    Put a test light between the negative terminal and the disconnected negative cable. If there is a drain, it will light the lamp. Disconnect things until the light turns off. Be sure to disconnect the underhood lamp first, if you have one.

    Probably obvious, but maybe not.
    Pull fuses to eliminate systems that are fused.

    I Had to put a relay in the 2nd and 3rd plug in on the alt. to stop the drain relays are excited by ign curcuit. they are the 2 relays on the right, the left one is the glow relay.Oh alt is an ordinary single post chev with plug in.
