Draw Test On Battery

[Dego]

My 2002 IS200 is having trouble starting after sitting overnight. It starts fine again after a drive to work and the alternator has had a chance to charge her up, but same problem next morning again. Voltmeter on the dash reads about 13 volts but when I turn the key the needle drops to about 3 volts. The engine will start but only just and the accelerator has to be floored. Called into a local Toyota dealer this morning and he has it booked in for a draw test in the morning. Does anyone know what this involves and what is the likely problem? I did run the Battery flat about a month ago when installing and testing a new head unit, but after jumping and driving again it gave no problems since - until 3 days ago!!! The Battery was fitted new when I bought the car in January.

Think a draw test will just be putting a meter across the Battery and seeing what its drawing when nothings on.

Then checking the Battery is ok (acid etc)

They put in a new Battery today, said my old one was knackered. Fingers crossed it will solve the problem. I'll find out over the next few mornings. Hope you get your's sorted SINGH182, good luck.

if it was a new Battery in january it should be under warranty and free to exchange? all come with one year and you can get 2-3-4 and life time warranty on batterys :winky:

I bought privately mate, so no way of getting a freebie. It's sorted now anyway, cheers. It would be useful to know about the instructions for future use. Could you send them to me please, Thanks
