A random thought to explain another "fix" for dying IMRC's: On NECO people have reported pulling the cover and giving the motor a spin will help resolve the pulsing problem (this is the case when the IMRC opens, but "flutters" causing a surging feeling during acceleration).
It's likely that the motor will always open and stop at the same spot as it pulls the cable till it can't pull any more. I'm curious if all that time sitting on a particular spot on the brush/stator whatever can lead to a bad contact, so the motor loses tq, unwinds a bit till it hits a new contact spot and then winds back up? Just random thoughts with no data to support it though

I dought that happends man , once the motor does that "spin" it spint well more then 360 degrees , go outside and take the cover off the IMRC and rev your engine holding down the motor, youll see for yourself that this trick of " spinning the motor around " is a complete joke and totaly useless. If you cant do that then i will be more then happy to make a video of it .

And it hasnt failed me yet, not ounce(thanks Scott). Its prob. been close to a year since i relocated it. And to think I dont have a degree in anything

Yes, of course it spins more than 360 - but it will always stop and hold at the same spot (after it's pulled the cable in all the way). If that winding is weak from bad contacts or burnt insulations on a winding, it could pose a problem. Again I'll admin it seems far fetched, but how would you explain the failure mode of an IMRC that always opens, but fails to hold position and surges partly closed back to open repeatedly, escpecially when hot???
As for you'r IMRC reloc fix Harley, just shows sometimes we could all use a degree of common sense more than anything else!

Dude honestly i think its more of a Transistor issue , My friends died, i took it and changed the transistor and it worked perfect , and the same issue happened with mine.
I'm not trying to start a war with you , but im mostly saying that people need to be aware that the transistor has a huge role to play in this.

ok, either way it has to do with heat....obviously the engine heat does not help...as for the transistor issue...Eh  need more concreat proof and testimonials besides yourself....this was brought up before a while ago, but no one supplied proof or could prove it to my knowledge, so its still a theroy. either way its not going to help bickering about it...heatsink won;t help, and niter will a fan...relocation is a proven way by a few people.

Was your's totally dead?
I'm no expert, but from most of the posts I've seen it seems to be more common to get the soft failure of "fluttering" that can be temporaily fixed or masked by moving the box to a cooler location, and I don't really know enough about how transistors fail to even guess if it could cause that so maybe you are right.

Mine hasnt died, and I havnt had any problems with it (didnt have any problems on my 150k+ 96 contour either...btw why do the two boxes look diff?) Even so, I think I will add a heatsink or something just to see if it looks cool, and to be different! Pictures to come, and for [censored] and giggles ill get a temp reading b4 and after and whatnot like that. Mmmm ghetto mod.

Just a note I found broken soldier connections where the right angle pins from the connector go thru the circuit board. I did test the transistor but just basic diode type test and voltage drop. While I was at I isolated the IMRC box with nylon washers I had laying around. 3/8 thick just enough to help as thermal break from the valve cover. It hasn't miss a beat since. Paul I would have hope the engineers designed the components for that high heat area? Of course I forgot about the bean-counters!

Transistor takes voltage and multiplies it ,same was as a car amp works , doing such a thing makes it hot , VERY HOT ..so like i said ...doing anthing with the IMRC is really worthless IF you know electronics at all .
How do transistors multiply voltage?
