Hi Hamish Should have put ACA is Automotive Computers Australia and their part number is IM113 . Also found another of my many books ... this one is TRIDON ( 1999 print ) ...... back then they had a Gold standard Modules with Lifetime warranty .... this book agrees with the previous , ACA info that the same module is in all those vehicles . Their part # is TIM016 TRIDON book offers some info on the Pick up coil . A failed pick up coil can cause hard starting , hesitation , no starting , rough idle and misfires . The pick up coil tell the module when to do its stuff . They have or back then had a branch in NZ 11 Waipareira Avenue Henderson PH (09) 836 5653 Fax (09) 836 5521 AUS 1300 362 263 Email... mail@tridon.com.au Don`t know if any of these will be any good still . Cheers , Peter --Previous Message-- : Thanks Peter : : I have not been able to find any info : about the modules other than a US : website for aftermarket modules that : seemed to offer only one module for all : HEI. : : The module is as you say, a flat box, : qwith angled ends, almost banana shaped : and with 2 pins at each end. So unless : I have struck two dud modules, that is : not it. : : The wires to the dizzy cap are on a : separate component which has a : condensor attached. : : I replaced that at one point so that : should not be an issue. : : The only part that I've not replaced is : the coil that goes around the shaft to : pick up the firing signal. It does : involve wires, so maybe I will replace : that. : : After that, maybe the coil which was : supposed to be brand new & looks it : is a dud. I've had new and near new : coils go belly up before. : : Thanks for your thoughts - always good : to have someone look at a problem from : another angle. : : Cheers : : Hamish : : : --Previous Message-- : Hi Hamish : : Thinking on it and yep i reckon module : or its wires but guessing . : : The first fried because of the lack of : heat sink and the reason it stopped : after warming up . : : Maybe try refitting the first module : and if it runs on all cylinders before : it stops , it may be telling where the : problem is ? : : The second running with a lack of : cylinders says to me module also ...... : the timing bit could be because it : triggers the coil and it is failing : internal but again guessing . : : I have ACA parts manual that with other : componets has ignition modules which : also has a sub cat which covers NZ only : . : : As i say i know very little about these : dissys ...... : : In the listing for CHEV it give 196 CID : through 454 CID 1974 through 1989 : ...inline 6 and V6 and V8 as all using : the same module . : : Same for BUICK 173 CID through 455 CID : inline 6 , V6 and V8 , same module . : : Same for Pontiac which is similar to : Buick capacities , etc . : : Some Alfas , Fiats , Jaguars , Jeeps , : Lancias ,Peugots , Renaults and 3500 : Vitesse Rovers . : : The same module is used in all the : above . : : It is rectangular with curls or angled : ends , it has two mounting holes . : : On one end there are to male spade type : , same size . : : On the other end there are two male : spade type , one smaller than the other : and the larger of the two is shorter : than the two on the other end . : : Interestingly and a different module : than above but .....for 3.5 ltr it give : a listing for NZ RR 85 on as being : different to AU RR 87 on as in : different part number and the pics show : them as different . : : The AU RR 85 and 86 are different to AU : RR 87 but that`s because they don`t : have the module on the dissy . : : The NZ 85 RR must have the module on : the dissy because of the shape of the : module . : : Cheers , Peter . : : : : :
