Any updates?
My new ICE Ignition is in and the car is up and running for the first time in months. We found the old coil had very little spark coming from it and thought the leads were a little too small, so I decided to bite the bullet, go with ICE, and replace the entire system - leads, dizzy, coil and CDI box. Car fires up better than ever, and now all it needs is a shot on the dyno for some fine tuning.
After reading the info regarding the ammeter bypass, he decided to leave it as is, but also run a wire from the ALT directly to the battery to reduce the load through the ammeter.
