is it a short???

I completed the turbo swap and runs great...almost.

My amperage has always been low and now I hooked up a air fule ratio gauge. It gets aa wierd signal. Half the lights light up. instead of one or two. When I hit the brakes it said the the mixture goes very lean. The blinkers also afect the gauge.

Before with the carbs it wasnt a big deal. But now i fear i will blow the computer. The car cuts out at random. The volt meter in the car bounces around with the blinkers and brakes also.

The onle place I can find non factory wires is behind the tach. Wich does not work. I am going to detatch it. Any other suggestions would be apreciated.

Is something grounded to a power suply?

what would cause this?

I knoe the air fuel gauge works it came with the engine and I used it on my toyota.
