My New Battery

[2erobrd]

I have no clock, but do have a Retro Radio, either way I have a 67 Dodge A100 and the battery never drains, so I getter get a good tester (no harbor freight units) and see if I can track it down. Once I do I am certain I may still need replacement battery. Question is, how many cold cranking amps do I need for my 2.8L ? is 600 CCA's enough?

I made a simple little test light, with enough wire to see it while I pull fuses under the dash, and wire it between the ground terminal and the ground lead. It then sends all current through the bulb. If you have any current flow, enough to power a light bulb similar in size to a running light, you will drain the battery. A radio memory will not be enough. Do not turn the key ON or try to start it or you'll have a mess of wire or at minimum a blackened light bulb. You then pull a fuse at a time until the light goes out and then you at least know the circuit where the drain is. You'll still have the fun of figuring out where exactly, but if the wiring is stock, it shouldn't be too hard.

As for CCA, 600 should be plenty.
