2005 dodge magnum 2.7 will not start new battery
I have a 2005 dodge magnum SE 2.7 engine. I was having starting issues where the starter would not kick. the car accessories all have power when the key is in the on position. I check the battery and found the positive terminal was VERY corroded and the battery was bad. replace the battery (810 cold crank amps / 1000 cranking amps) and replaced the positive terminal and negative terminal. I use clean wire on the positive wire and made sure the connection was good. It still will not start UNLESS I have a booster jump pack connected to the jump terminals in the engine bay. I can hear the relay in the back fuse box clicking when I turn the key. the front starter relay does not click thou. I swapped the relay with the same type and no change. the positive wire is a 2 gauge thick wire running the length of the car to the firewall and another 14 gauge wire going to the fuse box in the back. I have check both fuses for the starter and they are good. Any suggestions would be GREATLY appreciated.
