I was having issues keeping points alive in a brand X car and happened upon this site: http://nonlintec.com/sprite/cap_failure/
Sure enough.. every new condenser I had gotten where all junk. Basically fake. Even even name brands you used to be able to trust.

Before that I was drivability problems with another brand X car that uses the bread and butter GM HEI system. Turns out new replacement 4pin modules no longer seem to support expanding dwell with RPM. Ya you can get module for 9 bux now but they are not much better then points.

Then I was reading about the slantsix guys having problems finding usable distributor caps/rotors: http://www.slantsix.org/forum/viewtopic.php?f=19&t=60552

And now I bring you todays chrysler ICM. This box is sold under a few different brands anywhere from 13bux to 50.

I was asked to contribute money to help solve the civil unrest in Egypt, but I suspect it's some sort of pyramid scheme.

Yep the transistor is fake. cry

The little power transistor looks like "ST 981Q Morocco bu911t"
Not sure how long it would have lived barely being pressed up against the tin case for a heatsink even if it wasn't undersized.

And of course its the great guys in the mopar world bringing this junk to us.

Add a 1/10 of a cent sticker and charge $10 more.

I use this on my test run stand, cant say id use it on a car.

That is why I usually look for NOS parts if the cost is not ridiculous.

Its not just 'classic' cars anymore. Get up into the 15-30 year old range now and things are going down the drain quickly. More and more white box off shore garbage is becoming the only option besides used which anymore I have taken a less apprehensive approach to doing.

It has been said before I'm sure and I will say I do often now. Rockauto can be a gold mine for new old retail stock (NORS) on closeout. Last month I bought 20 NORS ball joints for less than $4/each, at one point they were $35+ each but discontinued by the mfg who also got gobbled up by a competitor... NORS drum brake hardware kits for $2.50/each and all good USA made stuff. On and on it goes. The stuff is out there if you dont mind storing it for use later on.

How do you figure these rate?

I bought two of these Standard LX101 units for a decent price. I really dont want to rip one open to see.

I dont know the ins and outs of the mopar icm but if you hook it up and stick a volt meter between the metal case and the ground of the unit there should be some voltage. Maybe something like 400 volts. I remember getting shocked from them before. I am going to go with REAL on your unit because if you look up the datasheet on the BU931 it's a "HIGH VOLTAGE IGNITION COIL DRIVER". Wouldn't make sense to spend the money on that part and then not use it.

I found thread talking about the ICM's but it's from 2014 and most of the pics are broken unfortunately.

Looking at photo's of old ones it seems most aftermarket ones used /\/\otorola or RCA made transistors.
Maybe someone who knows NOS or has a collection can share some more info.

I bought one of these and I am running it on my car now with no issues. Is there something wrong with this product???

AND... did he advertise it fraudulently? Have you taken it up with him before posting this?


The new parts = cheap sh!t topic is an important one, its a troubling reality, and garbage parts and shysters should be called out, but this smells a bit personal...

iagree A lot of aftermarket parts are junk, especially what you get from the chain auto parts places.

A lot of shadetree guys just want the cheapest part they can get, and the market has obliged...

Some of you flakes read too much into things, I was going to post Jegs also sells the same box but didnt see it as important.

Alot of mopar vendors sell cheap china junk. Better? Dont care if ya think so or not.

Either way whoever sells it, cant expect much for $31

Yeah - they have a life span of about a year. Was rehabbing a tin grille truck, bought one "just because" while doing cap / rotor / plugs / wires. A year of so later I ended up putting the 40 yr old original back in because the look alike went poof. Your mileage may vary but built like cheap crap is gonna perform like cheap crap.

BTW, not a recent development - the aftermarket has been building them with fake transistors for close to a decade. Clearly not 100% of them for that long but I think it'd be pretty hard to find a real deal aftermarket one today.

Well, here is my take. To understand what the box is, is to understand that its just a switch. Basically the pick up in the distributor sends a signal when the metal point crosses the magnetic field. This "signal" is processed with some electronic to add in proper timing, dwell, etc. That large transistor is the high current switch to charge the coil based on the low current signal from the pickup.
The new boxes probably make use of more efficient electronic components so it is possible to have a more efficient design. However, I'd still be comfortable with the larger transistor and heat sink for reliability. I think if it were me, and the new boxes are just shells, id go with MDS or Pertronix or others. If originality is a concern, then I am not sure what I would do.

I suspect if they spent the few cents properly heat sinking the little TO-220 transistor inside rather then on the big fake TO3 transistor and heat sink on the outside the box might actually work a long time.
The BU911 I found inside maybe underspec'ed to begin with* but not correctly heat sinking it is just condemning it to death. frown
I found a photo of a different aftermarket ICM. If that rivet in the case is holding the internal TO-220 to the case for heatsink then I see that as an honest design at least.

(*compared to PN#'s in the photo's of real external TO3 transistors I can find)

We source products from China on a regular basis, and have found the Mopar box available for <$4 in quantities of 250 pieces..

Just my $0.02... wink

Isn't this about the time MP's orange box went to crap too? I had an orange box from '91 that lasted hundreds of thousands of miles having been installed on several cars before it went bad. Bought a new replacement about 2006 or so, it didn't last a year. I still have the box from '91. It'll start and idle a car, but extended use.........things get interesting. hop

About 5 years ago, I had a 1988 Town Car and it needed a new starter relay, the thing mounted on the inside fender. Problem was I started it onetime, released the key and the starter stayed engaged, and could not shut off engine. I was lucky the battery cable was not tight and killed it that way. This was a low mileage and clean car.I went to NAPA and bought a relay. It was good for about 6 starts. Then the same problem.I took it back and put on another relay, same issue. I then checked the starter switch in the colum, looked good, I replaced it anyway. I then replaced the relay again, I think. same problem. So I put on a rebuilt starter, still having problems.
I then took off the 3 rd. NAPA relay and got one fromAuto Zone. Never had a problem after that.
Guess Napa relays were made with thinner copper wires or something.
t That lincoln was a very good riding car, rode better than the 97 Town Car I had.

I had six in a row go bad. Took them all to a swap meet, put a sign on them that said 'six for $5, none work, but the orange paint is pretty'. It was a joke. Until some guy came along and happily gave me $5. I said 'you know those dont work right?' He said yup! Off he went...

Its pretty bad when your box ov emergency electrical parts you keep in the trunk is full ov 40 year old pull-off parts from running cars because you dont trust parts counter parts anymore...

I thought I was the only one that did that!

A couple ECUs, a couple ballast resistors, a couple regulators, a rotor, a coil, some scotch brite and enough tools to swap all of it in a small little box tucked inside the spare tire.
