[QUOTE="KevinDIY, post: 8223436, member: 659609"] hey guys, I am trying to track a heavy amperage draw on my truck that manages to seemingly kill the batteries quick! The batts had a full 100% charge from the batt charger @ 8 amps over a weekend. The batteries were weak enough this morning that the truck was completely dead. Ive got a Shuriken medium battery upfront, and 3 NSB 90's (big) in the back. They have alot of reserve, so to completely drain them to me must be a huge drain. I really dont know how to track a drain, and dont know what setting to use on my meter to do so, I do have a current clamp to but Ive never used it.
