Battery Terminal Color

[Bingster]

I'm making some new battery cables and I assume the red battery terminal is the positive.  I've got a 50/50 chance.

By the way, I did use my hand grinder to cut the cable and it was smooooth. Thanks.

Red for positive .

these older car did not use red battery cable....the size of the battery post dictates which cable goes to which terminal on the battery......red became popular later on with the 12 volt system

All the cable is black but one of the terminal connectors is red.  Should they both be black?

[Plymouthy Adams]

you are using later aftermarket painted terminal that make it very easy for folks never to mix them up......using them painted as such is purely your call and nothing wrong with it whatsoever....

[Bingster]

Thanks.  Although I suppose the length of each cable is a dead giveaway.

[Plymouthy Adams]

as long as you using the correct gauge....not a big whoop there either...

Now, when you show your car, some lookers-on will be surprised to see the red-ended cable fastened to the block, and green going to the region of the starter.   Yep, old Chrysler made his cars positive ground.

I stampted the top of the lead posts on my battey with a + and a -. To help my sons remember what goes where, in the event they are out and need a jump. As mentioned all my cables are black.  With a 6V, positive ground, and all black cables you got lots of opportunity to screw up a boost.
