OK...now I'm confused real good....can we / do we use an in-line fuse to the Ing. switch? My uncle says that it will blow when starting? I think I had better ask Mr. Langdon his products are first class but his web site stinks as far as installation instructions and is very technical also BUT he is always ready with an answer and is a great guy...he needs a Web designer. My uncle says all points only draw 6 volts thats why the ballast resistor on the firewall to take it from 12 to 6 and 6 volt electric systems do not need a ballast resistor....learn something everyday from him! Someone wrote on another forum that pinging can deystroy a 235 how long or how many times do we have before we wreck"our" engine if we mess up the timing? Thanks to you all for the continued help and T/C Steve and UNC
