In preparation for my new "overnight solutions" ignition.   I've decided to replace the original start switch with a normal ign switch, and a Ford type solenoid.  I think I have the wiring figured.  But, as a check, do any of you have any tips?  I know sfa about voltage regulators.

Just make sure the ignition switch is the same as you take out. I just went thru this with a neighbors LT switch. Had to change it to a on / off pushbutton type start / stop for him. Not all switches are the same. I have a True Value Lawn chief now that I need a switch for and there are no numbers or letters on the switch to show which one would replace it. it will work to the run position but will not start the engine. I used a pushbutton between the two studs on the solenoid and it works fine now. Good luck. Roger.

Thanks for the replies.  I could have made it clearer in my post.  The start switch on my SS12 is used to "make" the heavy 12V current to start my tractor.  When the switch is turned "off" it grounds the ign system, that stops the engine.  It's when it is in the "Run" mode that I'm not sure of.  It looks like "B" on the reg needs to be switched to  +12.  Is this true?

My understanding is that you are switching from an unpowered ignition (CDI) to a powered ignition?

I would be VERY sure that is what you are doing before wiring in the switch.

IF that is the case you need a switch with a "I" on it instead of an "M" .

Most switches that were designed for Kohler systems with a coil would work.

Been there, done that.

I need to know if the regulator needs to have a circuit, switched by the ign switch.  I have looked at all the wiring diagrams that I could find..  All show the start switch, but not the internal workings.

Why reinvent the wheel ? A lot easier to just order one from Sears and forget it, cheaper in the long run too.

Do you happen to have the Sears part number handy?  And better yet, the wiring diagram?

Dies this new ignition require power for run or ground for kill?

That is the first question we must answer.

Is there a data sheet, installation manual, anything that came with it?

The new ign system requires +12V to operate.  So I have to change the ign switch or add a toggle switch.  I don't want to have a toggle switch on the dash.  So I am going to change the ign switch for a normal "give +12V to the ign system" one.  At the same time, I will add a Ford starter solenoid to take care of the heavy current needed by the Starter/Generator to start the engine. I'm uncertain about the "L" terminal on the regulator, and how it is handled by the original ign swit.

I think I may have answered my own question.  It was not the "L" terminal on the reg that I was interested in.  It is the" B" terminal.  Using logic, the ign swit in the run position must join  the reg "B" to the positive side of the battery.  

Thanks for your comments.

I'm sorry I didn't get back sooner. If it requires power to the new unit, You can use most of the wiring diagram from an Onan powered machine.

Are you sure Dale's system requires the juice to the new module he builds? I know his is supposed to be drop in replacement for the old SSI modules.
