Hello. I see in your post that NAPA installed the battery which I then must assume they hooked up the cables.....just curious but where they aware that the system is positive ground and did they hook up the cables to the correct terminals? Dave's point about the gauge of the cables is very critical......0 at least and 00 is better.......

Dave, is there a voltage drop when the key is turned on, and what would cause the amp meter to show a drop?
I can find no item that is activated by the ignition key accept the coil wire. I have no radio.

Thanks

Bob

When you turn on the ignition the ammeter should indicate the current draw of the ignition coil, typically about 2-3 amps. You shouldn't see a voltage drop, just an amperage draw.

I really can't say how the battery pole burned; however my mechanics did remove the + cable will working on the engine.
Best we not ask about it further.
Cables are all stock and in good shape.

I'm still looking into the starting problem.

Thanks

I think my starter is worn too much and needs to be replaced with a remanufactured item.
I need MAW 4018 Autolite starter which was used on 39 and 40 282s.
I've had mine refurbished brushes etc, no improvement.
Any help would be appreciated.

finally starts good. Went over all connections and grounds which allowed the starter to turn over faster. The voltage regulator stuck and killed the battery, replaced battery all is well.

Had the same problem and I just replaced the starter.

The car runs great once it starts. I just got a Petronix flame thrower coil and it says for 12 volt negative ground. I called Petronix and he said i's okay to use the coil. I an not sure that is correct as the out put depends upon the input based upon my limited knowledge.
Should I return it and forget about trying to get around the OEM system which may be my starting problem. I am seeking any solution to improve the start.
Any thoughts,
Thanks

Conventional point and condenser ignition will be more reliable than Pertronix in a 6-volt system.

Are the hard starting problems associated with a cold start, or a hot start? Or both?
