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, thanks to the advice of Jake and Rhody, I'm up and running again. Called my FLAPS yesterday and they got me a new Unilite module overnight and they price matched amazon.com for $89. Got it installed, everything wired up PROPERLY (including wiring in the relay for the fuel pump--thanks Jake!!!). Hit the key, and she fired right off. Now I'm trying to make sure it's all good. Set the advance to 12 deg BTDC @ 700 rpm warmed up, and it idles really smooth--no more 009 flat spot.
However, on my afternoon test run, she now lacks a noticeable bit of top end. Max speed is now about 70mph. I can see the spark advancing using a timing light when I rev the engine (haven't done so over about 1750rpm yet). I installed the grey/grey springs (Here is a curious point... there were two sets in the kit that 'could' have been grey. One set looked "more" grey and was a smaller diameter spring with a lesser spring rate--these are the one's I used) and used the 16 degree plastic key in the kit to set the max advance to 16 degrees. Didn't mess any with bending the spring perches. Any thoughts as to where my top end went? Also, what plug gap is recommended for the Mallory using NGK plugs from aircooled.net? (running .040" now--old plugs were .030" with the 009) From what everyone else with a Mallory says, it should run like a scalded pig. I'm sure we'll get to the bottom of it. As always, thanks tons!!! --Jaybird |
