Thanks Dennis that does answer my question why I should I use my extra battery instead of the Westy battery since the leads on the new light wouldn't reach. I was working at being careful with the electrics not wanting to shorten and burn wires etc.
I will use the alternator red lead + and the body or engine for the ground for the timing light and will recheck timing.

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.
