Yeah, I've heard this elsewhere too... "cause trouble" is an understatement, more like "destroy the control unit." An easy prophylactic fix is to put an inline fuse in the secondary pump power circuit---3A, I think. Should be standard procedure with any new-to-you 124. Of course this doesn't explain why my ACC just started acting like the pump has failed (hunting cabin temp at idle but working fine at speed), but the fuse is intact. :( Alex Chamberlain '87 300D Turbo '93 Isuzu Trooper
