Shaun P Posted July 27, 2010 Report Share Posted July 27, 2010 Help, I recently bought a 1973 CR TR6 (KHR 999P)and can not stop smiling or driving it. On Sunday after a run out the car died on me just before I reached home. On investigation it seems that the HT lead from the coil to the distributor cap had a high impedance (18500 ohms for a less than a foot length). The coil was producing a spark however it was not beefy enough to operate the spark plugs. After refering to the forums I have ordered a set of magnercor ignition leads as a replacement. To check my diagnostics I have borrowed a replacement HT lead to make certain that the high impedance was in fact my problem. I have a lumenation electronic ignition fitted ( I belive to be a FK116 model)and after some internet research proved the system is operating correctly. In my haste to prove that the lead was indeed the problem I replaced the distributor cap incorrectly and have manged to destoy my rotor arm and snapped 3 spokes off the electronic ignition'chopper'. Can anyone tell me were I can get a replacement rotor and chopper Yours Aye Shaun Quote Link to post Share on other sites

Shaun P Posted July 27, 2010 Author Report Share Posted July 27, 2010 Cheers, I will contact both Shaun Quote Link to post Share on other sites
silvertop_john Posted July 27, 2010 Report Share Posted July 27, 2010 Shaun, Been there, done that.... If Rimmers don't have the chopper wheels, the Lumenition fitting kits are available from other suppliers. I ended up getting one of these kits from Moss, and they were about £16. You get both 6cyl and 4cyl choppers plus some other fittings that you will never need, so if anyone needs a 4cyl chopper wheel, let me know! John Quote Link to post Share on other sites

Shaun P Posted August 10, 2010 Author Report Share Posted August 10, 2010 Hi All, Got a new rotor arm from the Dizzy Doc and she fired up with the old high impedance HT lead. Looks like my rotor arm was tracking to earth. Thanks Quote Link to post Share on other sites
