No spark

[Victorniner]

So figured I,d start a new thread for this one got engine back together found TDC set dist went to start and no spark not even at top of coil have 12v at pos. side of coil when key is in on position what should my ohm reading be between terminals of ballast resistor? Figure might as well start at beginning

What distributor? 12 volts when cranking? Need more info.

 

[Victorniner]

Msd ready to run and 12 v both terminals of ballast resistor when key is in on position haven't tried when cranking meter red 2 ohms when testing between terminals on resistor one side disconnected lol ran great before I pulled manifold I,m sure it's something easy thanks

If you are getting a ohms reading I would say the resistor is good, not common to fail and make more resistance it generally fails to a open.

 

[Victorniner]

Thanks that's what I was wondering so onto next component pulled coil wire and put metal in end and stuck to coil had somebody crank no spark

 

[La Hot Rods]

Do check for voltage when cranking.

MSD ready to run distributors are junk. I had a brand new one on our 409 that sheet the bed on startup, MSD said too bad out of warranty. I had to take the guts out of my SB one and swap it over to get the car running. Just bypass it and use a good 6A box it will work better anyway.

 

[Victorniner]

Ok but before I get to dist. I need to figure out why no spark from coil first

 

[La Hot Rods]

Two wires from distributor to coil? not hooked up backwards

 

[Victorniner]

should have thought of this before i ask question do,es this dist have a control module in it? at work now but will check when I get home

 

[Don Jacks]

Yes it does and it's most often what fails in these units.By pass it and wire the pick up to a 6AL or simular ign. box.

Wait a minute, MSD ready to run besides having a junk module does not use a ballast resistor!

 

[Victorniner]

oh well you know what I get when i assume the style. just saw the external coil and made that assumption will get my glasses on and see tonite when i get home thanks for the heads up btw the ballast resistor is connected

 

[Victorniner]

Ok so I have a MSD 8393 and it's running thru a ballast resistor to coil ran great before I pulled distributor so what do I need to buy to ether re wire or replace ignition module thanks

Everything you could possibly need to hook up any MSD gadget.

There is a pickup coil with two wires, it will be close to the center of the distributor. Hook those up to a MSD 6A or 6AL box.

Use the trigger only instructions. No need to gut any of the wires just route the two wires as James said and make up weather pak connection. After being left stranded along the road with a MSD crap module I bypassed it and use my ready to run distributor as a trigger only.

 

[Victorniner]

Thanks

So without googling which two wires are those black and red? Orange?

The wires you need terminate inside the distributor and are hooked to the module as I remember. You have to cut them at the module, lengthen them by soldering, shrink tube them, bring them out of the distributor and add a male/female connector.
