[V8] ABS problem fixed! (finally)

[kyle leatherwood]

Well,  my ABS problems got fixed over the weekend.  My problem was an ABS 
warning light on all of the time.  Well, to begin I ohm'ed out all four 
wheel sensors.  Ah ha! I found one sensor that the ohm reading on was so 
erratic it was impossible to get a constant reading.  Well, in my tracing 
down the system I realized that it is a WABCO ABS system on it, which is the 
same system that Freightliner trucks (the dealership where I work) use.  In 
a search through the ABS sensors for the A series WABCO ABS system that we 
have on the shelf, I found one with the same plug.  A quick ohm check proved 
my thought, it is the same ABS sensor.  $32.00 later I had a new sensor.  
However, the sensor didn't fix the problem.  My las thought was to check all 
of the ABS relays in the system.  Both relays onder the hood checked fine, 
but then I ran across the one under the passenger floorboard cover.  Voila!  
This relay has a 10 amp fuse in the top of it and the fuse is blown.  My 
guess is that the bad wheel sensor blew the fuse.  A new fuse and ABS sensor 
on and now the ABS system works like a dream again.  Thanks for everyone's 
thoughts and help.
