Alright so the deal is this I just bought this car not too long ago. I haven't been able to plate it yet because i didn't expect my insurance to be so high. While i was waiting to get the money together i would start it every now and then drive it on the temp plate it always sounded like it was trying hard to start but it always started the first crank. I went to start it the other day and it gave one crank and died i still have lights although they are very dim. I don't know if its related but the gas gauge light was always really dim. My car is stock expect for a stereo power acoustik DVD and i believe the battery is like a megatron 2. So with all the details my question is this i am thinking its the alternator but what should i pull to have tested first the alternator, the starter, or the battery?
thank you in advance
