12v coil or do I need 6v coil
 

Reference previous post from a couple days ago "Oil Pan Gasket Replacement", now I am ready to start that 59A motor on a stand on the garage floor.

I am a little uncertain about wiring in the basic circuit. It's a stock '46 -47 distributor with single wire bale clip cap, and the stock style condenser next to the vacuum break piston.
My plan is to run the positive battery terminal to ground, neg battery term to the coil and bump the starter post with the negative battery terminal. Just want to make sure it fires on all 8.

All I have is a 12v late style coil. Can I get way with using this for testing purposes, or do I need to get a 6v coil? Do I need anything else in line (other condenser) to provide the correct juice to the dizzy? Thanks, guys.

The coil you have should work just fine......
No resistor needed for this testing etc........

Think about stopping the engine. Unless your going to rip the wire off the coil a switch would be good.

Bubba, thanks.
Terry, switch was in the plan :).

This is NOT me.

When you hook up the 12v coil to your engine will it be wired with the + coil terminal to the battery + and the - terminal to the dist.

Lowrider, reading you reply, I thouight you were making a statement regarding the wire hookup from battery to coil. I see from your later thread, you have that as a question. My understanding, is the negative battery terminal goes to the BAT terminal (through an on-off switch) on the coil, and to the post on the starter to engage the starter. Positive battery terminal to the ground. If this info is incorrect, maybe someone can chime in and set us straight.
Thanks.

My answer for your situation was for a 12v system. The question I asked was for a 6v system. I'm more than a bit rusty on 6v systems. Haven't touched one since the mid 60's and you rarely saw one by then.

When you get it running, bring it up to 12=1500 rpm after checking oil pressure run till hot. Shut down re-torque heads when cold. Then put it in the car and drive it hard. Do-not leave it on the run stand to impress your friends, this can lead to an oil burner and low compression.

Follow up:
- New fuel pump
- rebuilt carb (ant colony set up residence in bowl)
- cleaned and reset points per the "scale" method
- primed the fuel system by cranking a while without plugs
- 12v coil (wired per my post #6 above)

If the vehicle system is 12 volts, use a twelve volt coil. If it is six volts, use a six volt coil. Original type coils need the resistor in series to reduce coil input voltage to just over 3 volts. If you are using a modern round 6 volt coil, most have a built in resistor, and don't need the one on the firewall. Just check the coil input voltage with the points closed to see if it is correct. If you check with the points open, you will just see battery voltage. Maintaining the correct coil voltage is essential to prevent burning the points and cooking the coil.
