Evening All, TL/DR: What's this dizzy? A few weeks back I drove the Scout about an hour away to visit a friend's farm so the kids could go pumpkin picking. It was a great day and I had been working on the Scout all summer and wanted to get it out with the top off. It had been running great for the past few months and I had just finished an engine rewire project. At the beginning of the season I replaced my MSD 82023 coil with an MSD 8222 because it would crank but not start and that resolved the issue. Also, the 8222 can be mounted horizontally where the 82023 should be mounted vertically. During this drive, truck ran great, then about 1/2 a mile from my destination the engine up and died while cruising at about 20 mph. Initial troubleshooting looked like I had air + fuel but no spark. The coil was extremely hot, unable to touch for any length of time. With the air cleaner off I could pump the accelerator and gas would spray into the carb so I was pretty sure it was a coil issue. So sent wifey back out into town to grab any universal coil she could find at the local chain store. Ended up getting towed to the farm by friend's Wrangler, which I shall never live down. Wife took the long way, so after about an hour I tried cranking it again and it fired right up. I thought, alright maybe it's vapor lock but installed the new Accel 8140 when she brought it back just to be sure. I've since mitigated against vapor lock by insulating the carb and fuel lines, but the coil issue has me concerned so was looking into that again as I reinstalled the MSD coil today. Per the instructions for the 8222 coil, a ballast is likely required for a "stock or points distributor" (exact wording below) and the MSD PN recommended is 8214 or a 0.8 ohm resistor. I replaced my dizzy back in 2006 with a part from NAPA but am unable to identify it. I see transistors under the cap, so it's an electronic ignition, but probably not an HEI of any sorts. I want to say it's a Prestolite, but NAPA's website today only shows points distributors available. Been searching for a matching image on the forums, but no joy. Can anyone help me ID this dizzy so I can pull specs? I feel the ballast is probably warranted, can anyone confirm? Never had one before and have had the previous MSD coil for at least 10 years which also recommends the ballast. Other Info I'm seeing some pitting/corrosion on the rotor tip, but it is 14 years old. The coil is wired per the diagram and is wired to an MSD 6AL. The coil's negative terminal is grounded to the aluminum intake with 0.7 ohms resistance to the battery negative. Edit: Coil is NOT grounded to intake - my mistake! It's connected to the MSD 6AL black wire. Engine temps range between 180-195. Ballast/Resistor Instruction in the MSD 8222 Manual When using the Blaster Coil with a points or stock style distributor, a 0.8 Ohm ballast resistor must be installed in-line of the positive wire. Failure to use a ballast resistor could result in personal injury or component failure. Thanks as always, seems every time I get something fixed on this thing something else wants to start acting up. In all the years I've had this thing the engine has never died while I was actually moving.
