no power please help
Here is my problem . 97 7.3 not getting any power to dash. nothing is coming on.
the story behind it
before winter drove it with minimal problems. something was draining batteries ( im assuming all the extra stuff put on by previous owners ). if i let it sit for more than a week batteries would be dead. after one battery lost a cell i purchased new ones and all good. right before winter i drove it home from work and then next day no power at all . so i thought maybe another battery died or cell died. pulled the truck in garage over winter. i have had batteries on a tender all winter . hooked back up and nothing again. took batteries to get checked at 2 different places and and both say good. i replaced all battery cables thinking maybe some were bad and while do so i took off all the extra stuff that someone else put on such as extra lights and etc. so with batteries fully charged and brand new cables all the way around im still not getting any power to dash. can anyone help me out with this. what should i be looking at ? what should i be testing ?

May be a crappy ignition switch, BTDT with these. Only recommend Motorcraft, the aftermarket never seemed to have all positions operational
Alts also can cause a drain, tried a drain test? 20-30mA is about it. Dealt with that for years on an IH Scout2
Also, bought a new batt for the black Burb. Always weak aka bad brand new
