Dear Bob,

That's actually a recipe for destroying the ignition system in
progressive and mysterious ways (because of over-voltage).  Correct
procedure for the Vanagon is always to short the coil output to ground.

But there's no need to crank the engine -- turn the key on and off,
rinse and repeat until leak is found.

Yours,
D
