The Stovebolt Site Forums The Shop Area The Electrical Bay Battery Load Test

So my battery made me buy a starter I think. It showed 12.6V then sometimes 15V. Seemed odd but I blew it off. So new starter drags also. I only have a multitester. i know a battery can take 250 AMPs and up when starting motor. I can't measure that under load. I did watch the voltage and it went tp 6.3V. But I don't know what voltage does during start. Never had to do that. Has someone seen or know what the voltage does?? The good old FLAPS guy didn't know how to test for sure or if his tester will give a load to battery. He said charge the battery and come back. No thanks. So I write tonight hoping to get help.
