Guest Matty Posted May 11, 2004 Report Share Posted May 11, 2004 Hello, Can someone tell me which Aldon Ignitor to choose for my 1981 FHC TR7? There are Delco, Bosch, Ducellier & Lucas. I thought it was a Lucas dizzy but the man at Aldon said it was a Delco, can someone clarify for me please. Many thanks, Matt Quote Link to post Share on other sites
rayjones Posted May 11, 2004 Report Share Posted May 11, 2004 Hi Matty, Mine is a Delco, I'm fairly sure, without looking, certainly not Lucas anyway Ray Quote Link to post Share on other sites
malcolm Posted May 11, 2004 Report Share Posted May 11, 2004 Matty. You need to take a look to be sure. On a later car like yours (and Ray's) it probably IS a Delco. Malcolm. Quote Link to post Share on other sites
mikehardwick Posted May 12, 2004 Report Share Posted May 12, 2004 Hi Matty As Malcolm says, your car probably has a Delco unit fitted - my '81 DHC certainly has. Just pop out the heater plenum and all will be revealed. By the way, I fitted an Aldon Igniter to my car last year, also an Aldon Flamethrower coil. The difference in response and revvability (is there such a word?) was notable and immediate. Mike Quote Link to post Share on other sites
robgeev Posted May 12, 2004 Report Share Posted May 12, 2004 Can someone tell me which Aldon Ignitor to choose for my 1981 FHC TR7? There are Delco, Bosch, Ducellier & Lucas. Aldon Ignitor? Zippo Lighter? Quote Link to post Share on other sites
TRishaTR Posted May 12, 2004 Report Share Posted May 12, 2004 also an Aldon Flamethrower coil Mike did you try the Ignitor without the Aldon Coil? Just wondering how much of a difference using the flamethrower makes... as I'm only running the Ignitor. Quote Link to post Share on other sites
mikehardwick Posted May 12, 2004 Report Share Posted May 12, 2004 TRishaTR- Hi - I fitted the Flamethrower some time after the Igniter (in the mistaken belief I could use it to blast MGBs out of my path) Only joking, I really quite like MGBs - wonder what one looks like with the hood down? Seriously, of the two units I think the coil made the greater difference - but I was advised that they work better in tandem. Hope that helps Mike Quote Link to post Share on other sites
malcolm Posted May 12, 2004 Report Share Posted May 12, 2004 What's the coil voltage? On a standard TR7 12v is sent to the coil when starting then a resistor cuts the supply down to 6v for running. Are you changing this when fitting uprated coils? Malcolm. Quote Link to post Share on other sites
mikehardwick Posted May 13, 2004 Report Share Posted May 13, 2004 I have to admit, Malcolm, I never gave the pesky ballast wire a thought. The nice man at Aldon said he was sending me a TR& compatible coil, so I just fitted it - and it worked. Just for the record, my voltmeter shows 11.75 volts across the coil LT terminals with the ignition switched on . Previous (1st) owner of the car made no mention of having deleted ballast wire when I bought the car, but he had an immobiliser wired in - where would I look for the ballast wire to check?

Guest BLBoy Posted May 13, 2004 Report Share Posted May 13, 2004 Out of intrest would the Lucas sports coil be as good a performer as the ALdon? Its just a little cheaper Quote Link to post Share on other sites
marvmul Posted May 13, 2004 Report Share Posted May 13, 2004 On two occasions, I fitted a new ballast resistor with the Lucas sports coil, in combination with a Lumenition electronic ignition. The ballast resistor, fitted in series with the coil, got very hot and was smoking after a few seconds. Did someone had any problems with these resistors? I deleted the resistor and the ignition is still working without any problem. Quote Link to post Share on other sites
