Crafstman Engine Analyzer..., how to connect? 20% points? Options

[yarin]

I bought this nifty device, last one on the shelf already opened/returned but it doesn't have an insruction manual with it.

I hooked up + and - to the battery, and the green aligator clip to the negative side of the coil.

With the car off it reads 60 on the 4 cyl scale. With the car running it reads 30? I moved the point closer to the rotor and it now reads 20 with the car running.

Is this device messed up or is my dwell angle really messed up.

Thanks for the info. 34 degree dwell for single point on our 914s???

Pelican says 45 degrees?

"You usually hook up the dwell meter by attaching one lead to ground and the other to the negative terminal of the coil. Start the car and measure the initial dwell angle. All 914s should be set to 44°-50° for all RPMs. If your angle is not in this range, remove the distributor cap and loosen the screw shown in Figure 1. Move the small set of points outwards to decrease the angle, or inwards to increase the angle. Replace the distributor cap and start the engine. Check the angle again and repeat the adjustment until it is within the proper range. The dwell meter shown in Figure 2 shows the dwell angle set at 45°."

What gives? (IMG:http://www.914world.com/bbs2/html/emoticons/chatsmiley.gif)

Mike - I'm fairly certain i'm using it correctly. The black/red go to the battery, and green to the negative side of the coil. There is no zero adjustment on this tool.
