Hi all,
Going through the motions of trying to get my '73 240Z started.
I bought it without an engine but the car had previously been running (before I got it) with a 280ZX distributor so all of the modifications required have been done I think.
The car also came with a MSD coil (MSD blaster).
I'm getting no spark at the moment so I have a few questions.
1. When should I be seeing 12V at the coil? When the key is turned to 'start' only, or when the key as turned to 'on' as well?
2. At the moment the only wires I have going to the distributor are the ones from the coil to the 'B' and 'C' posts on the ignition module. In some posts/ guides on upgrading from stock to 280ZX, the dizzy mount is also grounded with a single wire. Is this necessary?
3. So I can check some things, is this definitely a correct schematic? Any key differences between a 71 - 72 and a 73 240 that I should know about?
I still need to do some proper diagnosis with a multimeter but I thought I'd ask in advance of me going and doing some further investigation.
Thanks and as always, advice is appreciated!
