Troubleshooting Battery Drain

Fellow C Body owners,

I am trying to track down a parasitic battery drain problem I currently have on my 67 300 w/ 440. If I measure between the battery post and cable end i get a reading of .199 VDC. I have a painless wiring kit installed by the previous owner, if i pull the 50 amp MAXI fuse it drops down to .03VDC. I have tried pulling every fuse out of the box and i can't get below a .16 VDC. My car still has the stock distributor with points, condensor, etc..The battery is a new Optima.

Thank you, 67300
