Exile Posted September 8, 2019 Report Share Posted September 8, 2019 First, the facts: engine starts right up, so long as it turns over. It will start when barely turning over, even after an attempt when it doesn’t turn over, so this is not an engine issue batteries (4) are whatever the seller had laying around, 925, 650, 950, 825 A two batteries showed bad with cheapo tester at rated amps, but showed good at 750a my tester would not test one battery, would just restart the menu when attempted Truck starts after sitting in shop on charger charger says all batteries are 97% individually, and 87% when connected to all truck doesn’t like to start after sitting out for several days not connected, cranks slowly or not at all replaced voltage regulator, get 14 v when driving now starts ok after driving my conclusions: i have a drain somewhere- i can fix that, or disconnect batteries batteries are not great best case would just be to buy all new batteries, or better yet, all new truck, but would prefer to understand the issues at play here my questions will batteries work ok in a group if they are different ratings? will a higher amp not great battery pull the others down even if it tests ok at lower amperage ? what kind of amps do i need for a s60 12.7 to start? Thank you for your patience and assistance. Quote Link to comment Share on other sites More sharing options...
