Hi all,
New member.
Recently obtained a 1989 SC from good friend a couple months ago.
Was his parents car, garage kept, very well cared for. Almost in mint condition, 53000 original miles.
Drove it home and on a few short trips after that. Shocks felt a little soft in normal mode but besides that, everything worked like new.
Most of the time at my house, it's been under a cover.
Was away from home for a month and the battery completely drained.
Charged it back up but now have the "Hard pedal Amber Anti Lock and Red Brake Light always on" failure.
Read the article by Duffy Floyd, 1989-1992 Thunderbird SC ABS Systems.
Started troubleshooting at the 4 pin connector to the ABS pump motor.
I'm getting 9.9v and 10.3v off those pins.
This tells me the relay and pressure switch are probably working.
The motor is getting voltage but not running.
Only thing I haven't tried is hooking 12v from a good battery directly to the pump via the 4 pin connector. Duffy's write-up says I should be getting "at least 10v".
Not wanting to do the Hydro-Boost Conversion, want to keep this car all original if possible.
Looking for advice / recommendations on a repair.
Regards, Ken
