Hoping someone can tell me how to test the tci module on my mk3 Its got no spark, redone/checked all conections then ran for 5mins then cut out now stuck with no spark, the module should be bolted to some kind of heat sink which its not so thinking its overheat ? Should i have it bolted to something to keep it cool ? Its running bike carbs so it was fitted with a mk2 golf ignition system set up The ignition module part no is 211 905 351 D
