Question for John Z or anyone who knows

1961 Corvette

I am hooking up a temporary ignition to test and break in my rebuilt motor that sits on my body off chassis. I want to verify that the resistor block is between the positive side of the coil and the battery. Also to shut down I just disconect the positive battery connection? Does anyone know for sure if this is correct? Thanks guys for any and all help. You're the best!

Yes, that's true.

When starting the engine, You MAY need need to use a jumper across the ballast resistor until the engine starts. If so, pull it off when the engine is running.

If you decided not to incorporate a ballast resistor, it would probably take more than the 20-30 minute break in period to damage the points with 12 volts, but the points cost money too.

Thanks magic and c5. By the way c5 illustrations work really well for a guy like me.

Here's how I do mine - 2x4 temporary "dash" mounted on the frame, with components set up just to handle ignition, tach, temperature, temporary electric fan, and oil pressure; the battery is on the floor. The cross-brace has the partial cluster, ballast resistor, coil, 12V and ground junctions on it (all the other "spaghetti" is unused body wiring - this was my Grand Sport "first-fire"). I've used this same type of setup for many projects over the years, works great.

Thanks John, you showed me this once before but I had forgotten the details. Thanks for posting it for me again.
