Hello! I'm trying to find the 80 amp fuse for the abs that is located in the engine compartment....it's an 89 740 ti, with a nasty wheel shudder on what seems like the front right wheel.

I pulled the transient surge protector fuse
(10 amp) under the drivers kick panel, but I'm not sure if that would disable the ABS.... cleaned the front wheel sensors, checked the pads and rotors and all seems well, but there's still a pulsing coming from that side, even when I'm not braking. It goes away when turning left, gets worse when turning right.

I just want to completely disable the abs, just to rule it out, and that damn 80 amper is hard to find!

There is two 40 amp fuses in the engine bay, one on either side, one is square, one is rectangular. the ABS control unit is under the kicker panel as well, and the booster(gold)? unit is in the engine bay.

Can anyone tell me where the 80 is? or could some previous mechanic put a 40 in?

I just bought the car 3 days ago, and I know my 700's turbo and NA quite well.

Never had one with ABS before....

Thanks!!!

What makes you say there is an 80 amp fuse for the ABS. I do not see one in the schematic and I have never had to replace one. I have done multiple transient surge protector fuses and other than that I have never seen any 80 or even 40 amp fuses for the ABS.

I'm just going by what the manual says (haynes)...it definitely list's an 80 in the system.....somewhere!

Good God! Could my Haynes be incorrect???!???

Thanks anyways.
