Someone here was kind enough to lead me to a schematic for the controller on my 6.5 KW with an L600 engine. My original choke is rusty, and so I bought a similar one on Ebay (Sisson 700 series). But, the Ebay chokes are always 6 volt, with only one connection for the 6 volt hot wire. On my unit the original choke had two leads running to it, one is hot all if the time, and one grounds when you hit the starter switch. I would like to use my Ebay 6 volt choke. I noticed on the schematic that the L654 had one wire running to the choke that becomes hot when the engine cranks. Why did they do that, and can I use the L654 wiring along with a resister (I have an old ignition wire in ceramic resister)?
