Olds 215- Do I need a ballast resistor wired in?
Finally getting my 215 powered Model A going. I ave been wiring it. It seems like the coil might be getting hot, but I'm not sure. Maybe it's normal? Just making sure I didn't forget something. right now I just have a wire from the ignition on positive terminal to the positive on the coil. Is ths wrong?

Remove the coil connections, put a meter across the +/- terminals and check the resistance.
If it's a standard 12V coil you'll see around 3 ohm, and that doesn't need a ballast. But if you see 1 - 1.2 ohm then it requires a ballast. In that case you should also make a direct 12V connection to the coil for starting - take a feed off the starter terminal. Ivor |

Re: Olds 215- Do I need a ballast resistor wired in?
OK. I understand the need for a wire from the starter to the coil. The stock Olds 215 wire diagram shows a resistor wire, so I know I need one. My question is what size? How are the rest of you doing this? Are you running coils with a built in resistor?

This is a ballast.
[www.flyingspares.com] Probably the most expensive you could find. Here's another. [www.ebay.co.uk] I bet they're pretty much the same. What resistance did you see across your coil? Ivor. |

I ended up getting one at O'Reilly Auto. Part number RU6. The price was $6. Maybe this will help other in the future.
