which coil???
hi guys firstly i need a coil for my 1300 xflow with points dizzy
does anyone know whether i need a 9v or 12v? ballasted or not?
and secondly iv got a few kicking around the garage but no markings , is there a way of testing a coil to find out what type iv got?
cheers in advance
chris
ps if all goes well and iv got a coil that will work i might well have her started tomorrow

As for the first question regarding ballast or non ballast coil do you have a ballast resistor wired in ? IIRC it may be a grey cable in the positive
feed for the coil . Easy way to check , measure the voltage at the coil positive terminal , non resistor should be near as damn it battery voltage.
With a resistor it should be approx 9volts As regrds tseting the coil its been year since I did that and my memory isn't what it was , however
if you fit the resistor coil to a non resistor circuit the engine will start but will burn the points out due to condensor failure after just a few
miles . Any coil should get you up and running but would suggest getting the correct type.

thanks for your reply rusty but iv no wiring in just yet, so quick answer is no i havent got a resistor wired in, was hoping of just getting the
engine to turn over more than anything , one step at a time right reason for the question really was because iv a few kickin about and wanted to
use one of those to crack it up, but really wanted the correct one if needed

Unless you have a ballast resistor fitted you need a 12v coil.
If your existing coil has round terminals or has a white insulator top or says Fomoco or Autolite or Ford Motor Company anywhere on it is about
99% certain to be a ballasted coil.
If in doubt buy new in the oldays it was simple only about 3 kinds of coil but with so many different electronic ignition coils around any of thje
coils you have kicking around are unlikely to be suitable unless they say "Joseph Lucas 12V) on the up.
The coil for an earlyish (1970s) BL Mini or MGB or 1960/70s Series Land Rover is what you require.
