Hello,

As title states, I have a battery draw on my 71. I lose about a half a volt every 8 hours my battery stays connected. I've searched this forum for ideas, and YouTube. What I've found is that I have a 1.9 amp draw. I'm just curious if I tested my diodes correctly, as I think that's my problem. Multimeter on diode setting, I put my black lead on the battery connection of alternator, red on case and it shows .535. Hook the red lead to the battery connection with black lead grounded, it's showing 1.9. This is without the battery itself connected. Does this mean my diode have gone bad? Did I do this right?
