Trunk Mount Batt. Opinions needed

Unless that thing is 14:1,if it slow cranks with only 8* of initial timing, check the main ground wire REALLY good. Check positive cable as well for deterioration. There are all sorts of issues that arise from that one ground cable being loose or not having a great connection with your engine. Friend just went through weeks of charging issues, then checked ground cable, yep loose. Tightened up... engine cranks a bunch better and the charging issues resolved.

I like to do this if the engine cranks slowly. Take a jumper cable, attach at battery neg and the other end to the engine. Same as making the neg cable a BUNCH bigger. Does it crank easier? If so, you have a cable/ground issue.
