Need to replace a coil on my Euro 328. Searched the forums to no result - are there aftermarket options or am I looking at an OEM unit? Thanks
Good luck looking for the coil, but I heard that 328 coils are no longer available here in the USA, so you might have to go to Maranello to order one. I saw a 328 in Conn up on 2 milk crates yesterday....is yours red with badges on the front fender? Also, I THINK I saw a bum sleeping in it.
Interesting...my wrench reports that in his tenured experience 99% of the time when a bank goes out it's the coil (but could of course be the pickups). And in fact the last 5 328s he had w.a bank out were due to coil. Are you saying it may be instead the transistor and not the coil itself?
Yes and those are available by themselves for far less money. I know T Rutlands and GT Car parts both sell them. I am not sure about Ricambi.
Can't one of the aftermarket replacement coils from the various ignition manufacturers be used? Or is it a matter of wanting the original equipment (which I certainly understand)?
Rutlands has a part # of 124273M for $154.65 It was not sold by Ferrari seperately so I don't know the origin of the # Its the one spare part I carry when I travel.
If it is just the power module (aka "transistor"), WAI has a generic version: http://www.wai-wetherill.com/products/partimage.cfm?wai_num=XM631
Negative - at $941 for OEM I am not interested in keeping it original. As far as my searches (and to my wrenche's wit) there is no aftermarket alternate - for the coil, that is. This is the transistor, correct? Nice - thanks fellas. So if its determined to be the transistor (and not the coil) either the TRutlands reference or the WAI ref is the component to replace? If we were to simply swap coils from the firing bank to non, and the problem follows the coil - just so I understand - it could be the coil OR this part (transistor); and we'd then need to determine if it's the trans. or the coil, correct? Just last week I dealt w.similar problem on my Ducati, thought it was the coil but after swapping around discovered it was one of the two pickups on the flywheel. Got in there, swapped it out and she's healthy again. I guess when it rains it pours eh? Maybe Italian machines are like women - too long in close proximity and they pick up on eachother's, uh, physiological characteristics
Well, I don't know a thing about the specific coil(s) but if it's a 12V powered coil, why won't any 12v coil work? Seems like since all a coil does is convert 12vdc to around 40kvdc, it wouldn't be an issue at all. I'm NOT trying to be difficult, just trying to understand.
PM sent. That's what I would've thought, but from what I garnered from trying to find alt coils at the very least there's a difference between injected and carb'd animals w.respect to their coils. I'm sure Steve or Brian can speak more to that...?
The 328/Mondial 3.2/TR all use a coil/transistor module combination. The transistor goes bad. Ferrari never offered it by itself. If indeed the coil was bad I supose you could jury rig it, fab a different mounting bracket, reconfigure the wires and supply a seperate mount for the transistor but I have a feeling I would not like the aesthetics of the modification and wouldn't be in a hurry to do it to someone else's car either. All he needs is a $150 transistor module. 4 screws and one plug and its done. Like I said, I keep a spare in the car.
Yes, you've got the right picture in mind here. The coil and power module can also be separated so just swap the power modules, not the coils (or vice-versa) -- if the problem follows the swapped component, that's the bad one; if the problem stays on the same bank, then the bad component is the one that was not swapped. (Of course, this assumes that you are really sure it's something wrong with the coil + power module assembly and not the dist cap, rotor, coil wire, etc..)
*** SOLVED **** Brian and Steve, thank you as always for your input on this. The culprit was in fact the transistor. I went ahead and ordered the WAI unit for $16(!!!) and my wrench swapped it out, now she's back on eight. You guys saved me $750 and $924, respectively! I feel like I owe you guys a beer.
I'll tell you what, Rifledriver and Steve M. are two of the smartest guys here. The two of them have saved my ass many times!
Hey David I forgot to ask,where did you source the replacements from?It might be good to keep spares like Brian suggested.Thanks
You'll have to find a retailer for the WAI part, p/n XM631 Ignition Module. I went through Boston Auto who were very helpful and had it drop shipped over-nighted which I don't think they typically do. http://www.wai-wetherill.com/products/partimage.cfm?wai_num=XM631
The link above for the WAI XM631 Ignition Module isn't working anymore (old posting, perhaps the site is out of business)... does anyone have a current source for this part?
