Getting close to wrapping up my 10 month nitrous install. I moved some of the wiring and was checking to make sure I had everything wired correctly. I used the master cylinder as a ground for a second. Everything worked, finished the wiring, hooked up the fuel line and go to test the fuel solenoid…once, twice, three times, fourth time power goes out. Pull number 23 from the fuse box under the dash and the 10 amp is blown. For power I am taping into the overhead console for the power switch and purge button, for power for the solenoids and TPS I spliced into the power for the wiper motor.

Any reason why I should have blown a fuse? Do you think it was the ground on the master cylinder?
The ABS light is on and the turn signals do not work (which I guess the #23 fuse is for). Would the #23 fuse cause the ABS light to go on?

 

A Ford tech told me once it's pretty common to see fried abs computers from people not disconnecting there batteries when working on there electrical system. Always disconnect the ground before doing any work or this is more than likely to happen.

The other common reason the abs would go out is the sensor in the diff has gone bad. With your working on the eletrical system and blowing fuses I would say you more than likely fried your abs computer.

 

that sucks!

 

Sorry for HJ.

Where is the diff sensor located ?

Thanks

 

VSS sensor on top of the differential housing ie; rearend.

 

Thanks !

 

my abs light has been off for about a year and a half now... i hate abs in this truck so i never realy tried to hunt for the problem. Probly the rear sensor since the light came on few days after i had the rear end rebuilt

 

it was just a fuse. 10amp believe number 23 on the fuse panel.

 

Interior fuse panel ?

 

yes, i believe it also controls the turning signals??

 

Ok, thanks !
