Ouch!
I suspected late 70's,...well Elvis was still rockin!
There is an accumulator, traced it to the steering and brake unit. Bypassed it to test, no go. Checked for a fuse, or flow control valve, but none was found at base of free lift cyl. Dont know if one should be there?
Blocked free lift cyl to test for bounce, it's gone! sending cyl to rebuilder, possible seal breakage.
I'm wondering about the brake accumulator and motor. Never heard that motor come on, no power to it. We pumped the brake 50 times to deplete the reservoir. Then a warning light came on with buzzer upon re-start.. It went away when i pumped the brakes with engine running. that's normal and Had nothing to do with Hyd cyl, but wondered if the brake unit was not functioning properly because the electric motor never had power.
Will keep you posted on Cyl repair.
Thanks for the tips!
