2.1 idle relay Experts

[Bassyaks]

I keep burning up the voltage regulator in the idle control relay, it there an upgrade for the replacement part. every time I turn on the a/c it burns the Voltage regulator. Is there one that will tolerate the a/c being turned on.
hy is that a/c popping the relay??

Thanks

something funny going on, the idle controller does get a signal when the ac is on, so that idle speed can be increased to allow for the extra load of the ac, kind of like it get a singal form teh power steering pump when the pressure is high (pump working hard).

I'd look to see what signal the AC is actually sending to the idle controller, I am not sure what the signal should be, but It maybe is supposed to be a gorund being made?

anyway see what the ac signal wires is sending when the ac is switched on.

How much current can the Amplifier handle? is there a replacement part which can handle the current? right now I'm using a NTE185 it's rated 80-80-5volts 4A, PD 40W would the NTE36 work at 140 a 12v ??
Where does the A/C signal come from?? I think the signal is not grounded, it is a positive signal.
What else is sending signals to the relay besides the A/C and P/S and Temp sensor?
Sorry for all of the questions

I think I'm going to try the NTE36, I have no idea what the results will be, if someone knows please stop me if I'm wrong!!

How electronic experts will swapping the Amp work??

You mean the output transistor? The large transistor is not a "voltage regulator" per se, although it does look like one.

I suspect that there is something wrong with the idle stabilizer valve itself. Maybe it has an internal short. Does the Bentley have a resistance specification for this component?

Try this: Unplug the idle stabilizer valve, and then turn on the A/C. Does the transistor get hot? It shouldn't.

The NTE185 is a PNP transistor. The NTE36 is NPN. These are not compatible. I don't recall what transistor I used when I repaired mine 7 years ago, and I don't have a stock engine anymore.

You are correct on the part description
I'll try your suggestion this afternoon if I have time

Thanks

Have you pinned the A/C and fuel injection harnesses and made sure each terminal is in the proper location in the plastic connectors?

Frying ECUs and now ICMs

Are you using all D series parts including the wiring??

What year is your van again???

Sounds to me like one of the grounds is hot and backfeeding when you turn on the AC.

I am throwing away a complete rear AC unit with column wires...you want it?
I also have a complete AC unit still in a van. You can have it if you pull everything, I have no interest in it or time to part it.

What is the difference between the "B" idle control unit and the "D" version? I just replaced my "B" with a "D". The valve hums/vibrates and the engine idles fine now.
