Help with Bosch electronic ignition please

Hi,

I'm really hoping someone can help me out here.

At the end of last year I purchased an Alfa Romeo 33 8V racing car. When I bought it it still had the standard wiring loom in it. This seemed like madness to me so I ripped out the old loom and rewired the whole car myself with only the cirsuits that are required for the regulations. eg lights, fuel pump, rain light, wipers, ignition etc. No frills.

After doing this I couldn't get the engine to start. I had no spark. After much head scratching I decided the best bet was to buy a new amplifier. I did this and the engine run. It was tuned up and driven and seemed ok. Sounded like a bit of a misfire but put that down to poor quality fuel and running a bit rich.

On going to restart the car its not working again. The dizzy has been tested and is fine, new HT leads, rotor arm, dizzy cap etc. Then I recalled I hadn't replaced the ballast resistor I had removed when I took the loom out.

What I suppose I'm hoping to hear is that me not running the ballast resisitor has fried the two amplifiers. The only other thing I can think of is the signal cables do go close to an HT lead so I shall use shielded cable and rewire those.

Anyone got any ideas or can confirm/deny my suspicions?

Many thanks,

Sam
