Had the alt/bat light come on a couple of times.
Engine running, had a fish around, leads, belt etc. Things looked OK.
Then whilst pressing Alternator Conector, the belt and bearings started to sing, Houston we have connection.
Seemed to come OK. This has happened several times, but alas on Saturday, when washing ready for the Clubs Xmas Luncheon, it went crook and stayed crook.
My diagnoses is either a faulty socket or its internal pins/connections, OR more likely the sockets metal fittings that extend out of the socket and are soldered to the cct board located within the Alternators rear section. For my US readers soldered is your Soddered, not sure why you guys drop the "L".
Anyway I'll remove tomorrow, pull it down, I have some resin core Solder with 2% Cu (copper). Much stronger, tougher.
