Call MSD I'm assuming your bypassing the magneto so it is completely out of the ignition circuit except for distributing spark Via the rotor, yes or no?

Electrimotion makes a switch so that you can change the inputs. You can start it on the mag, then once it's running you can switch it over to the grid. I usually likes to have the timing really low, like 15-20 so that it can start really easy, then have the Grid have the correct timing, like 28 or so, depending on the combo. Then the Grid can control all the down track stuff
And 16v should be able to spin it up no problem. But I would definitely install the switch

Every blower car I have been around has one, and I have never, personally, seen one fail. Not that it can't or won't happen! But that is why you set the timing on the mag low. If the switch does die and you can only run the mag, the timing will be low enough that you probably be able to go up and down the track. Maybe not as quick as you would like, but you can make a hit and come back and fix it. I would rather have the switch, and the chance of it failing, than have it 24v. It's a complete pain to wire a car up both ways, with 24v and 12v.

I started all my mag engines off 24 volts. I don't fully understand what you are doing but doing a 24 starting system is easy with a series/parallel switch. It doesn't require much more wiring and it will start on 24 volts and run everything else on 12 volt.

Trigger made it run dead on. The trigger will fire it at 15 degrees and run but not at 21 where I need it to be??????

It doesn't require much more wiring and it will start on 24 volts and run everything else on 12 volt. I have a few old (new) series parallel switches at work on the shelf but I really don't think this would need one. I'm pretty sure I can ground one side of battery "a" and run a tap off the other side to run all 12V items, series battery "B" to it and run a tap off the other side to power 24V to the main power stud on the starter. Series parallel would be handy to charge the batteries but I have no alternator
