While working on our Ramcharger I discovered it had the old canister type coil. I happened to have a MSD Blaster 2 coil laying around so I was gonna throw it on. It came with a ballast resistor and while doing some searching and chatting with a fellow RC owner I found out that it needs it. However I can't find the stock one. It's not on the firewall where they normally are. I've read about some "lean burn" setup but I have no idea if I have that or not. Can anyone help me out with this?

 

unless the truck originally came from the factory with the 360-4 barrel engine you won't have one on that truck. Is there a computer in the fender behind the battery? If so then no ballast resistor. If that is the case then hook the wire going to the + side of the coil to the resistor and add a wire from the other side of teh resistor the rest of the way to the + terminal on the new coil,. some coils have the resistor built in, some (apparently like yours) don't.

 

Yes I discovered I have the lean burn setup. I just threw the coil on there without it. Are you saying that's a bad idea?
