Part of the spark plug circuit includes the current goes from the center electrode to the outer ground electrode. Ground or eventually chassis being a key. As such the timing light should be connected to the vehicle power supply so that it is also connected to the same common as the ignition system, including the spark plugs. You can easily connect the timing light to a chassis ground somewhere and get power off the alternator terminal. The degree delay function only works by time delay versus speed and is a very crud indication or measurement. Someday I will figure out why some folks think it is better this way than to follow the Bentley. The Digifant modifies the timing curve based on coolant temp so part of the procedure is to disconnect the temp 2 sensor to go into a default and set the timing at idle speed.

My old timing light was D.O.D. , Had to purchase a Craftsman Sears timing light Hopefully I used it correctly!
Here is what I did
GOWESTY has a template to mark the pulley at 35 degrees which I used.
I used an extra 12v battery connect to the timing light Warmed engine to running temp.
Set the new "Advance Timing Light" to zero Used the onboard tach to read 3000 rpm Adjusted timing to line up with the new 35 mark on the pulley.
My concern is that I didn't adjust the timing to far advanced so I ruin my 2.2 Westy engine Any thoughts or suggestion before I drive it out for a test run?
At 3000 rpm timing is set at 35 degrees this is what GOWESTY suggests with the "Advance Timing Light"
