Soft Dash 1994 3.9 petrol
Blink code 2-6 so replaced the Stop Light Switch and cleared but still getting 2-6 fault, probably fuse or bad earth but cannot locate the 5A fuse!
Under the passenger seat (RHD) I have the 3 relays but only 2 30A fuses, all piccies I can find have the 5A here as well but not on mine, being a late soft dash did they re-locate it elsewhere??
 
It may be but was wondering if anyone knew the exact location of the 5a stop light switch fuse on a late soft dash?
 
Hold up!! Are you sure this is a fuse problem? Have you checked the switch is getting power and that the switch is actually working. Don't forget it is a two stage switch.

I had a similar problem with my '91, every now and again I would get an ABS fault that pointed to the brake light switch. The switch just needed adjusting so I would suggest adjust the switch first and see if that sorts it.
HTH
 
I don't have a wiring diagram for a '94 soft dash. Latest I have is for a '92 and the brake light circuit has a 10A fuse, B1 in main fuse box, feeds to brake light switch and brake lights. Also on the same circuit trailer pick up (brake lights), ABS ECU and Cruise Control pick up. Good luck.

Cheers for that, think it may be an earth/power issue as it is a new switch and I have fitted them before so know the set up, all brake lights etc working so probably a bad earth, anyhoo it is off for a pre mot once over so hopefully sorted soon
 
Just because it is a new switch doesn't mean it works!! (I'm not joking either).
If you still have the old switch, test it. As I said earlier, I had a peculiar problem with mine and all that was needed was to reset the brake switch - push the pedal down then pull the plunger out and release the pedal. There are two types of brake switch for the Classic IIRC and the difference is a subtle one, I'm a bit rusty on it now but it was something silly to do with the way the switch is adjusted but also remember it is a two stage switch, I can't remember which way round it is but one set of contacts is only for the brake lights, the other set is connected to the ABS ECU. I believe any ground in the circuit is through the brake lamps as the switching is only for +12v feed rather than being for making or breaking ground.

After a quick review of the ABS schematic, I think I understand your reference to a 5 amp fuse. These fuses are located under the passenger seat. You need to remove the lower side plastic trim from the seat base, this should expose some relays and fuse holders, in here you will find all sorts of potential gremlins so do have a careful look, especially check for corroded wires/connectors and also check for earth wires (normally black), make sure all are clean and secure.

You should see 3 relays - ABS warning light relay, Valve relay and pump relay. 4 fuses - pump relay, stop light switch & diagnostic plug, valve relay and then the big 30A maxi fuse for the pump.

If you're messing about getting blink codes from the ABS ECU make sure you have properly cleared down all stored codes, this can take an annoyingly long time of faffing about!! but also make sure you disconnect the jumper wire and put the relay back.

Let us know how you get on, it could be it was just the brake light switch and a replacement sorts it, but if not I am afraid you'll need to be getting busy with the multi-meter.
