Triggering Msd MC2 channel box with 1 wire

[sc2dave]

I have a 4 cyl bike with a MSD MC2 bike ignition. dual coil, waste spark. The stock pickup coil has 1 magnet, with 2 wires coming out of it. How can I temporarily wire the pickup coil wire or wires, so that it triggers 1 of the ignition coils? The oem neg coil wire usually goes to 1 of the MSD input wires and the other one goes to the other input wire when it's permanently hooked up. I want to do this just to verify if it can be triggered via magnetic pickup or if I'm going to have to get a Hall Effect trigger setup. Thanks

Hi, I am the mechanic, lol....I am familiar with the stock ignitions used on Japanese 4's, but not what you're using...let me think about, Tony

The output of the magnetic pickup is a weak voltage signal. It needs to be converted to a square wave strong enough to trigger your MC2.

MSD 8509 is designed to do that.

Damn, I'll need 2 of those. any other options?

You could use two OEM replacement ignition modules.

They trigger from magnetic pickup and can drive the coils directly or trigger your MSD.

I just checked rockauto.com for 1980 Ford Fiesta ignition modules as an example

Airtex/Wells 5A8 for $12.23, only 12 remaining.
