ABS pump does not charge accumlator

..purch 91 9k T with known ABS prob...light on steady...but braking w/o antilock feature was sure and smooth. I've driven a couple of mil mi w/o
ABS so it wasn't a big deal for an otherwise swell red car. Seller was less than honest when he failed to mention that if the car sat a few days, you'd be treated to a dead battery. Seems there is a constant drain when the car is all alone. I traced the current drain to one of the ABS relays in the box above the master cylinder. I removed them and went on a test drive. Yikes! NO Brakes. Well, OK, no boost and a real hard pedal. That was then. I found a device that would auto disconnect the battery after a voltage drop and auto reconnect when a load was put on. All was well for about 6 mos. However, upon startup recently...back to no boost. Yes the reservoir is brimful indicating that the pump has not charged the accumlator. How shall I proceed to diagnose what may be two problems? I have read dozens of posts but lack the comprehensive knowledge to reason this out. Thanks to all.
