Title: Alternator light flashing when on full lock
Post by: fish on January 17, 2006, 22:42:29: Anyone know what this might be, seen it several times now only flashes for a second or two. I have checked alternator wires and belt tension, all seem ok, any pointers?

If the belt seems tight enough, it might be worth checking that the PAS pump isn't on it's way out, check to see if the pulley is wobbly. If it is, then it's a sign that it's probably going to fail at some point, and leave you with no alternator, and very heavy steering.

The PAS pump belt is very hard to get tight enough to stop this IMHO, I slacken the pulley bolts to alloy the pulley to slew, then tighten the pump adjusting bolts. Tightening the pulley puts an extra bit of tension on the belts. I have know people using a jack to tighten the belt :shock:
