This is a 74 XJ12L, V12 with 4 strombergs. Whotta oddball, but it is all factory. I am installing a "re opus" kit from New Zeland. It is a new circuit board that replaces the board in the caveman opus box. Uses the same ballast resistor, pick up, ign coil etc.When you order one, you have to tell them how long the wires are, how many etc, so the board is "made to fit the application". I put one in a 76 FI car a couple of years ago, and all was well. In this case, I have never seen the car run. Towed in, some no name coil (that had split open !!), and no spark. New "lucas" coil(made under license...). I have tested it six ways from sunday, and it appears to switch the coil, but still no spark. I took a points distributor, and rigged a circuit to just test the coil, and it has sparks in it.... The guy in NZ sent me a couple of tests I have to run yet, but I had to move the XJ12 out and do some other work. Things are stacked up pretty deep here at the moment. I just sent out a nice 120DHC, I have the XJ12, another similar vintage XJ6, an 89 XJS in for ABS work, a DS 420 l;imo I am in the middle of an engine swap, and some major suspension surgery on a 66 Etype. My plate is overflowing.... Not a bad thing tho.
