Gen1 GS300 Electrical fault?

[Am123]

Hi everyone.

I am having an issue with my 1997 gen 1 GS300 Sport where the engine starts but immediately cuts out. It died on me right after getting my mot done.

I was advised by the AA that it was my alternator that was not charging the Battery. So I got the alternator replaced, put the Battery on charge until it was full.

Put the Battery in but now the dash is not working at all, and the car immediately cuts out. When it died the first time it wouldn't even start, now it starts no problem but only runs for a couple seconds.

I'm at a bit of a loss here as to what it could be. A new Battery maybe? I'm not very adept with the mechanical stuff so any help is much appreciated.

 

Thanks

Check the standing Battery voltage against the chart below.

Check the tightness and cleanliness of both Battery connections, the 'other ends' of those connections and also the engine to body earth strap (sometimes also a gearbox earth strap too).

Hopefully you'll find one of them to be loose.
