I don't think even alfa have a wiring diagram :lol: ... seriously though I'd do as David C recommends ... the best thing to do is sort out the known problems first and then you can realistically start fully diagnosing the other faults ... (more often than not a single fault can have multiple symptoms ... even if they don't all appear at once)I cannot understand why the battery light came on at the same time as the speedo stopped working, is there a fuse or anything in the same line, does anyone know where I can get a wiring diagram.
Sounds like there is a definite problem there then, it should be 14v when running, how old is your battery?? (worst case alternator???)I have checked the fuses on top of the battery, these are ok and the battery voltage is approx 12v not running and still 12v when running when it should be approx 14v. With my luck they are probably not related.
Yes there is, the engine earth lead, I've seen this once before, the engine earth lead has not completely snapped but enough has gone and the battery has slowly drained, though it still thought it was charging, then the speedo dies because of the low voltage (if you check it with the engine running it should be 14.4V NOT 12V), so there are 3 things you need to check first, Battery is OK, Alternator is OK and the Earth strap, you still need to fix the ABS fault (probably a front wheel sensor), but that wont be the cause of this other trouble.I cannot understand why the battery light came on at the same time as the speedo stopped working, is there a fuse or anything in the same line.
