OK,
On to phase three of the Unilite install. I got the dizzy drive properly indexed and the dizzy set at TDC on #1. I verified by thumb-over-hole and by watching the valves. Now I am getting no spark out of the dizzy. Car ran on 009 dizzy two days ago. Replaced coil with new Bosch blue and installed the Unilite. I have checked and replaced all of the spade terminal ends, so I should have good contacts. From the Unilite, I have the brown wire to engine block ground, the green wire to coil neg (I assume that's the one with the minus sign), and red wire to coil positive (the one marked "15"). I say no spark, because I am getting no flash from a timing light (which worked two days ago, and shows to have power--it's digital). Attached is a pic of the coil. Let me know where to go from here.... |

OK, let me see if I can keep an expensive lesson from getting more expensive:
1)After a crash course in the multimeter, the unilite module is smoked. Used their testing procedure from their website, and there is no voltage drop when the module is blocked. It's reading a full 12 volts off the negative side with the optical window blocked. Should be 2v... So, I'll get a new module ordered post haste.. 2) The yellow fused wire in the photo is the power supply for the fuel pump. No power coming through it. Unplug it with the key on, and the fuel pump goes silent. Is this a good place to have the fuel pump powered from? 3) The two black wires twisted together running to the same side of the coil as the yellow wire are the key-on hot wire for the coil. Good 12v with the key on... 4) How do I verify that the lone black wire on the back side of the coil is the tach wire? No voltage coming through it... 5) Last, and most importantly, am I correct in my assumption from Jake's post that it does not matter which side of the coil you use for positive or negative as long as all of the positive wires are grouped together on one side(key on 12v/fuel pump/mallory red), and the negative (tach wire and mallory green) are on the other? I really don't want to burn up another Benjamin on a Unilite module... I'd be better off taking up a cheap habit like Cocaine... Thanks again for the input!!!! --Jaybird |
