My Holden barina keeps stalling and then cuts out when baterry light appears on dashboard. My mechanic changed, fuel pump, fuel filter, carburetor. Had a new baterry fitted by RAC in Perth, Australia not long before problem started. Sent to auto electrician and they suggested change alternator, but it may not fix the problem. My mechanic has tested alternator and says it does charge the battery, so it can't be that. My mechanic can't seem to find the problem or reasons why this keeps happening on occasion. It's a safety risk to drive since I don't know when it may stall on the road or in traffic.
