Hi!

I have bought second hand Alfa 75 1.6 (1991) and I have small "problem" with Alfa Rome Control panel. I have read on the net that they are known to light up with no apparent reason so I'm not sure is that the problem.

What happens is that when I push the break paddle the "Brake pad, brake fluid level warning light" and "Stop lights bulbs/switch/fuse/connectors efficiency warning light" light up (simultaneously) and when I tap the paddle again they turn off. I had a mechanic look at the break system (fluid level, break discs etc.) and on that end everything is OK, so I'm guessing some kind of sensor/wiring problem.

Did anyone had similar problems? Dose anyone know how to fix it? I guess it is not big of a deal but it is distracting to the driver (me..lol :) ) to get all those red lights turning on and off so often. Tnx.

start with checking earths.... (if all of those light up) alot of the systems use shared earth points, if one goes bad, it creates a whole host of bizare things and alternative earth sourcing problems...

failing that, you could do what i did.... do away with the useless thing alltogether!

Main earth points are:-

1 each side engine bay (front cross member above rear of headlamps)
1 on bulkhead in seating compartment (behind dash fuse box area) it shares the plate mounted by 2 m6 screws that the block connectors locate into
1 each side of floor pan beneath rear seat (inside of car)
1 by handbrake lever under centre console
1 main from battery to engine
6 (or 4) to engine for injectors

it seems i have a similar gremlin.. BUT mine all flash from the time the key is turned to when its shut off. the control lights just randomly flash... my brakes are fine.. oil, good pressure... and it didnt really sit long enough to have the earth problem or w/e but i mean would that still be the best bet to check out??
thanks! OH
and kinda off topic- but im getting my clutch redone very soon- next week maybe? very excited!!

i'd do the earths as a matter of course just to eliminate them.. lets face it, if everthing else is working when physically checked (ie senders, condition of whats being monitered by senders etc) what else can you do apart from wiring issues which include earths!!

heres a good laugh for you all, when i bought my 75 everthing appeared to be working ie no random lights...
now that ive stripped the car out in prep for conversion and resto, i can see why! some bugger has been in there and grounded a few wires thus eliminating any signal to the ARC!

why are you getting excited about a clutch??!! yours slipping that bad:confused:

THE ARC in my brand new Alfa75 used to do this back in 1989..but onyl after it had been in for a service and had the brake pads out for cleaning. It was a common problem, solved by cleaning the wire contacts on the brake pad wear sensors and reassembling them with some grease to keep water out.

Also well worth checking is the float on the cap of the brake fluid reservoir. The float gets 'fluid logged' (as opposed to water logged..bur similar idea) and sinks and sets off the low fluid warning and the ARC of course. Its a simple fix. Some replaced the float with cork, some get a new float assembly..which is difficult to find now.

I suggest you check this out before chasing earth problems. You might also speak to Alfa specialists like BLS who are very familiar with the 75. They may have a 'fix' for you or point you in the right direction.

Hi! Well the problem has magically disappeared (at least for now). I'm guessing since the last owner did not drive it much the problem was in earthing. Since I drive it fairly regular I'm assuming the problem (maybe moisture or something) has corrected it self. I'm glad I didn't start to chase those earth wires :).
