Does anyone know if the coil on a 1989 V* uses a 1.5V ballast resistor,
or not?

Dunno about the V*, but the V8 of that age ought to have a straight 12volt
coil. Easy to confirm by sticking a voltmeter between coil + and a good
earth, with the engine running.

Coil is FUBAR'd I think, it's arcing to earth, so was trying to find out
if the one on my mech's shelf was a useable replacement, but evidently
not, as all his are marked for use with a 1.5Volt ballast resistor...

As a short term measure, stick a 12v coil on and see if it runs ok, you
won't do any damage. If you put a ballast coil on and feed it 12v, you
'could' burn it out. Measure the voltage as I suggested with it running and
if 12v, then leave the coil fitted. If 6v to 9v, then fit the correct coil,
they are normally marked on the base, eg lucas 12C6 is a 6v coil, for use on
a 12v system with the correct ballast resistor (early carb rangerover, in
this case). BTW, the ballast resistor will have its value measured in ohms,
not volts.

You can run a ballast coil without a ballast for ages without any
problem - I ran one on my hybrid for 5 years and AFAIK it's still going
strong !

Just make sure the coil is a V8 one though, a 4 cylinder coil has a
slower recharge time so will tick over beautifully but will then the
engine will run like a dog at higher revs.

I found that out the hard way after swapping my 2.25 for a V8 !

more to the point, don't put a "points" coil on an electronic dizzy or vice
versa. The first combo will give you poor running, the other way around
will overheat the coil PDQ.

I'd add that it probably depends where the coil is mounted and how much
free air cooling it gets ...

Ah, can you get coils rated to run at 6 volts, because I have an old truck
with a 6 cylinder engine which is 6 volts, can any one out there suggest a
coil ???

Thanks guys, having read all the possibilities, I'll go to the Lucas
place on MOnday and just buy a new one, seems easier :0)

Use a ballasted coil without a ballast - it'll be pretty close to right.

Lucas 12C6, without the ballast.

Ok I will try that coil thanks for the help
