I have had a problem with this for years, but have totally ignored it. I have done all the obvious i.e. 1/2 watt resistor in wing, cleaned sensors,checked for bent pins and bled brakes. But after a check on all the fuses in the engine compartment, I have found that i have no power going to the abs valve fuse. Anyone ran into this, if so what to do next?

 

After doing some searching I found this website www.bfranker.badz28.com/fbody/abslight.htm. I thought I would give this is a try and it worked just as advertised. Well I figured since I have been driving the car without abs for years, why try and fix it now.. The ABS INOP light now comes on as you start the car and goes off after two-three seconds and stays off. Anyone who has this mysterious light, I recommend doing this one wire fix. Thanks for all the help!!
