Help! Timing (electrical?) problem in my 73 bug.

Well, I've almost completed a mechanical overhaul of my 73 standard, but have run into a major problem... I'm trying to run through the standard static timing procedure, but the test light stays on constantly, regardless of how I rotate the distributor (a 009, which appeared to be working properly when the car was last run about a month ago). I switched out the light for a multimeter, and it reads a constant 12 volts no matter what I do (though it does fluctuate a tiny bit if I rotate the distributor or crank). I double-checked the point gap, and observed the points opening and closing as normal, with no effect on the voltage reading. I've double-checked the connections on the coil and they're all right, and I normally have no difficulties performing a simple tune-up. What do you gurus think may be going on here? Thanks in advance! (bad pun alert)

With one lead of the light grounded, touch the other lead to the advance plate with points Closed. The light should NOT light.

Touch it to the side of the points where the Grn wire goes, with the points Open. The light should light.

Hard to put in words, but what I'm saying is- Check that the advance plate is grounded and that the points are good (continuity thru the wire).

Agree w/ Jim. Sounds like there is no continuity between the negative terminal on the coil and ground going thru the points. The reason you can use a test light to set your timing is based on the principle of electricity taking the path of least resistance. When the points are closed there is a (near) zero resistance path to ground. When the points open, the path thru the test light becomes the lowest resistance and electricity flowing thru the light causes it to lights up.

If necessary take the points and condenser out of the distributor and make sure there is continuity thru the entire path. Also make sure the distributor is grounded well.

There was another post somewhere that mentioned ignition problems because of a bad transmission ground strap.
