Hi guys, got a problem with my Kastreet 1.6.

was driving and all of a sudden the abs light, airbag lights came on and a number of other lights and my car just lost all power!

I jump started it using a mates car and jump leads and it held its power till 5 mins later and it ran out of battery again! I only bought this battery 9 months ago!
if i jump start it it runs, leave it for a while to charge, i take the leads off, turn engine off and back on again and the battery again has completly no power!

Someone said it can be the wiring going to the alternator, or the alternator itself or battery.

Also if it is the alternator, what other engines/models can i get this alternator from? as kastreet are quite hard to find in scrap yards

Someone help pleaseeeeeee Thank youuu!
