What components control activating the supercharger:
Fuse-13
charger pump
clutch
pulse module

Pls complete this list my supercharger is not kicking on. I replaced the pump and now I have 2 good pumps.

If it did not kick in with the engine cold you should have realized it was not a pump problem.
I would say you have to check that the SC clutch gets power or not first. Then work back, I am certainly no expert and have not got a clue what tells it to kick in, sorry. Maybe I should start to learn.
I would suppose if you checked for power at the fuse 2 in RCM ? you would know if the power was getting to the SC clutch. That is the fuse that would appear to me to control the SC clutch.

 

Thank u very much for sharing your supercharger knowledge with me.

 

Rip it,
how do you know the S/C isn't kicking on?
Is it just a total lack of speed and power?
You are aware that the car has to be actually moving for the S/C to kick on don't you?

 

Supercharger testing on an SRT-6 - YouTube

An old Woody vid.

 

I finally kicked back and started studying the manuals. Very good details in there on TS things such as the SC. I pulled the RCM and discovered the relay that controls the air pump is defective. When that relay picks-up the contact that the wiper would mate with is no longer there...vaporized. I am surprised F4 (40 amp fuse) was not blown. The air pump motor is probably faulty, haven't got there yet.
Yes I know the SC is not kicking on mainly because I don't hear the whirl noise, the car is quick without it. It's kinda like being catapulted off an aircraft carrier when it kicks in.
What I originally was asking, not very clearly, was info such as SC on = coolant temp ok + intake air temp ok + manifold pressure ok + etc...You probably would have to speak German in get that info.
I'll keep all posted as I progress. Thanks

 

From Woodies video, I would say :
1. Not in Park, Reverse or Neutral
2. RPM > 1200

Das ist was ich denke

Having had the pump fail on mine, i would certainly not describe the car as 'quick without it', in fact it felt like the car was starting out in top gear, and certainly not as quick as a NA would be. The supercharger whine is VERY subdued with the stock intake. I cannot hear it on my vert (stock with K & N filters) ...........compared to the needswings on the coupe. If you have a stock intake, maybe it is working and you just can't hear it ............only way to tell for sure is to wire an LED like Woody did .............

 

Make sure the shifter isn't in "Wet" mode. I've made that error.

 

I think I have a RCM lying around if you need one.

If you think it is not working unplug the wire to the clutch and try it again. It will be really slow if it does not work at all. if you feel no diference it has not been working.

 

Not in "wet" mode....lol..... that's a new one.... S/C will not kick in if the Intake Temperature Sensor says it's too hot. So, if the pump wasn't bad, maybe the ITS is bad. Sensors go bad too... So, no fuses blown, no bad pump, I would look at the sensor...

 

No it's not. Someone who's not familiar with the switch could easily have it in the wrong position...and I wasn't the first.

Having it in "W" (wet) could explain what the OP's experiencing.

 

Thanks for the offer Billy22Bob. I ordered a new one this morning ~ $165 shipped. Not in "winter mode". Maybe I am having a "senior moment" and the SC is fine. Unplugging the clutch is a good idea to be sure. I metered the air pump wiring is ok and motor reads ~ 0.2 ohms. Air pumps are ~ $750 new. I jumpered the air pump direct from the battery via a 40 amp fuse and ran it for 30 seconds. At this point I am concluding the RCM relay was a piece of junk from day one. If I smoke the new one at least I will have 4 spare relays to make repairs.
Semlinger would the SC work with the air pump not working? It probably would, I don't know? The CEL has never came on and I have driven at least 200 miles like this. When I install the new RCM I will post the results........Thanks for the help

 

Geeezzz....WET MODE.... winter mode/summer mode....not 'wet' mode... just sayin' but that wouldn't be it anyway I can haul *** in either mode.... whatever...I think I will tear into my RCM and take a look... it looked fine last year...but who knows...

 

Happy to argue with ya. Look in the OM. "W"= wet.

 

If w is wet then S is .......woody

 

Where is that diod wired in?? Is it at the plug in front of the S/C? Is one side hot and the other ground? Thanks

 

You are BOTH correct :
And I was thinking all along that it was (S)uper and (W)impy

Winter? Who's talking about winter? This is Houston. It's going to be 77F this weekend and these cars don't belong in snow anyway.

The OP stated he has the shifter in standard (or not wet) mode. That's all I was asking and it's a valid question.
