Guest rar7775 Posted March 2, 2007 Share Posted March 2, 2007 Hey guys, I have a '72 240 Z. A couple of years ago I put in a msd 6al ignition box along with a pertronix and tach adapter. For some reason now the car won't start. There is no spark from the coil. I've tried connecting the coil straight to the battery (positive to positive), which has worked before cos i had the same problem a few months ago, to no avail. Still no spark out of the coil. I've been messing with this thing for hours. I was reading in the archives and found that someone had a similar problem and it was the condenser. I was wondering if that might also be my problem and if it is, where is the condenser and what does it look like? Any other ideas that it might be??? Thanks for the help in advance!

getZ Posted March 2, 2007 Share Posted March 2, 2007 First of all, be careful about leaving a coil hooked up to 12v. An engine while running, pulses a coil to only fire when needed. A constant 12 for an extended period of time will overheat and blow up an oil filled coil. I know this from first hand experience. It's an oily mess that goes everywhere. This nice thing about an MSD 6 it makes a nice trouble shooting aid. Put the output of the coil to a spark plug and ground the electrode of the plug. The white wire of the MSD is used to trigger a spark and by grounding and ungrounding the white wire you will get an arc across the spark plug gap.
