TAD and TAB solenoid voltage issue on 86 GT?
having trouble getting these solenoids to actuate, I checked for vacuum leaks and that is good, checking voltage on these shows 9.9 volts or so, is this too low to activate the solenoids? I am getting a KOER 44 and 94 and the bypass valve is not sending air to the diverter valve which would explain those codes, though I can manipulate the the valve with direct vacuum and send air to the diverter, but i don't think that is switching between sending the air to the the heads and the catalytic converters either? both solenoids hold vacuum and measure out at 72-ish ohms. Any ideas would be appreciated. Thanks!
By the way, I do have the ford racing sensor package with new TAB and TAD solenoids but the connector is different than on my 86, will they still work if I find the correct pigtails?
