    Wiring the Ballast Resistor to the Magaspark Coil, Help please ????

    Evening all.

    I just received the Lumination Optronic Mega Spark Coil with the Ballast Resistor (recommended by Rimmers for use with the Lumination electronic Ign kit).
    I must say I was none too impressed with receiving the package from Rimmers (who have always come through top notch before)..........
    The coil has obviously been wired before, so had the ballast resistor, The coil mount was second hand & damaged & the pre-used box it came in looked like it had been thrown down a long flight of stairs........ but never mind....... as long as it works........ or it will be going straight back.
    Anyway........
    It came without wiring instructions (although Rimmers said it would) & I have no idea how this ballast resistor is wired in ?
    I assume it simply bolts to the coil mounting bracket ?
    There is a black wire bolted to the blank side (I assume thats the - side), is that an earth wire ?
    So where do I wire the + side to ?
    Does it go to the + or - side to the coil ? or does it get used as a bypass between the coil ?

    Any help would be great.
    Many thanks, Andy.

    Ballast Resistor usually sited on the bulkhead near the coil Andy. It looks like you're right about the earth (white slate) and it also goes to the coil positive (white orange) according to the wiring diagram in the ROM
    Paul - 3 projects, 1 breaker - garage built and housing 2 white Stags. One runs, one doesn't

      Thanks for the reply.
      I take it you mean that the Black wire on the Ballast Resistor I simply earth to the body with a screw.
      And the + side of the Ballast Resistor I wire to the + side on the Coil.
      So the actual wiring on the coil is exactly the same as on my old coil except for an extra wire I connect between the + on the Coil & + on the Ballast Resistor ?
      Is that right ?????

        It looks secondhand?

        Why are you not sending it back anyway?

            The ballast resistor must be wired between your ignition switch and the coil.

            So... you feed the ballast resistor with an ignition live 12 volt feed the other end of the ballast resistor feeds the coil. You should have a wire from the starter solenoid that bypasses the resistor at start up so that wire also goes to the positive side of the coil. DO NOT EARTH OUT THE BALLAST RESISTOR!!

            You need to download a wiring diagram from the internet... just google the lumention system and you will find one. Do not wire this stuff up if you are not 100% sure about what you are doing. You will most likely fry the lumention module and waste all your money. You wont get it back under warranty if the module has been wired incorrectly.

            AKA previous post!!!

              Hi Andy,

              Sorry to learn that the Lumenition Coil was supplied in that condition and without the usual wiring instructions. We will swap it over for a pristine one if you can post it back to us quoting return authoristation number 49858. If you wish to keep the coil you can download the fitting instructions from our website here :- http://www.rimmerbros.co.uk/Item--i-GCL132MS , you only need the ballast resistor if your car is not fitted with one , as far as we know MK1 Stag has an external Lucas 3BR ballast resistor fitted as standard and MK2 Stag has a ballast resistor built into the wiring harnes and not visible to the naked eye.

              Kind regards

              Andrew Mundy

                Thanks for the input everyone.

                I downloaded the wiring instructions from Rimmerbros & I also downloaded the wiring diagram from Google images.

                So that's sorted apart from what Andy from what Rimmerbros typed ^above^ stating that the Mk2 Stag already has a Ballast Resistor built into the original loom & cant be seen.
                I wasn't aware of that ?
                My Mk2 already has Lumination ign fitted but had just a std coil with very loose rivited type terminals that would result in the car not starting sometimes until I wiggle the terminals.
                I thought rather than just buy a new std coil, ill buy the correct Lumination one from Rimmers. I just assumed the Ballast Resistor was an advisable add on to improve spark ?
                So do I not need to wire in the supplied Ballast Resistor, or is there a simple test I can do with a volt meter to check if the cars original built in Ballast Resistor is still there ???
                Or would my car not have actually ran before on the old coil if my cars built in Ballast Resistor wasn't there ???

                Rimmer Bros......
                Thanks for your reply.
                It wasn't a rant but when I opened the damaged second hand box, I did think at first that I had been sent a faulty item that had been returned by mistake.
                But then I found my invoice in there too & thought, well maybe that's the only one you had, but wasn't too happy about it.
                It has obviously been bolted & wired to a car previously.
                But as long as it works ok, ill keep it.
                If it doesnt work I will send it back for a replacement quoting 49858 as you quoted in your post.
                Thanks, Andy.

                    If you have a MK2 with a ballast resistor wire (Pink / White (or Grey) to the positive side of the coil) You dont need the block resistor.

                    If you want to know more about a cars ignition system and remove some of the mystery over the wizardry have a read of this. Its all quite simple really! http://autorepair.about.com/cs/gener.../aa052502a.htm

                      Andy, most of our cars have had many owners, and many 'mechanics' will have had their paws on it. Just in case the ballast wiring has been removed, or bypassed this simple test is always a good idea.

                      TEST: Disonnect all the wires from the coil NEG. Then put a voltmeter on the coil POS. Short the coil NEG to ground and measure the volts; this should read about half battery voltage. Then take off the short and the volts should go up to full battery volts. Its as simple as that. If that works you already have a ballast fitted and wired correctly.

                      Cheers

                        I just finished work & checked the coil wires.
                        They are indeed pink/white & grey but disapear down by the gearbox & has modern insulating tape wrapped round them.
                        So im not taking no chances.
                        I was just about to do your test but my volt meters battery is dead.
                        So Ill get a new 9v battery while shopping in a min.
                        Just one thing though.......
                        Do I do this test with the ign on or off ?
                        Sorry to sound a bit thick but im not too keen on Shocks.

                        Thanks Andy.

                            Did the test & indeed my Mk2 does still have the original Ballast Resistor wired in.
                            Just under 5v when coil shorted & doubles when the short is removed.

                            Thanks everyone for all your input.

                            No more embarasing popping of the bonnet in the petrol garage or outside the shops to wiggle the wires .

                            Andy.
