1988 3.2 Cabriolet with ABS Had been sitting for a while with electrical issues. I replaced the main board with a nice repro from G.T. Car Parts and most all was well... Decided to replace all the fluids before driving it again, and bled both the clutch slave and four brake calipers with fresh DOT4 fluid. Upon starting the car & pulling out of the garage, a great cloud of smoke came from under the front hood, along with an acrid metallic smell. Looks like I smoked something. How do I diagnose this? Don't want to install a new part & smoke it as well. Also looks like my only option here is to replace the entire "Hydraulic Control Unit" as I'm not seeing any part # in the schematics for just a reservoir. Would love to hear if there are any other options.
