Coil Balasted ?
Earlier post asked how to identify if coil balasted.
Suggested I put meter across +/- terminals, if 12v on start then drop when key in normal position then balasted.
Tried yesterday.
Put key in and turn on, engine not running(not to start position) 11.5v.
Start, 11.5 V. Once engine running and key on normal position 5V.
Is that balasted ?

Its a Ford XFlow 1600. Not sure what the loom is out off either Ford Capri (late 1960's as its a 691 block not 711M) or Triumph Dolomite (its a
2nd hand project).
The current coil has no markings on it. But on the top are two terminals marked + and -. I am measuring across those two terminals. The large centre
one goes to the dizzy.

WRONG!!!!!
dont measure across them!
the -ve goes to the contact breaker or the like. It might be open or closed and screw the reading.
the +ve is the feed to which any ballast , or direct 12v, will be connected.
Make all measurents with the black lead of your meter to the battery negative or chassis.
the volts at the +ve will depend on the breakers being open or closed - if engine isnt running.
So, run the engine. If you get near as dammit the same as the battery volts on the +ve terminal, its not ballasted. If its around 9v or so, it is.
check the battery volts against the +ve - cos a 12 v battery is at 13.8v or so with engine running at decent revs. The +ve coil will be close to
battery volts (within a volt) if not ballasted
